At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Apricus Australia’s current product, downloads, warranty and service pages plus all three registry identifiers without a login. The official Issue 12 all-in-one installation manual was captured; its cover and specification page name APHP-R290-260 and PDF page 37 publishes seven descriptive entries in the Fault Code column with possible causes. Those literal display labels were dual-pass extracted as status indications. APHP-R290-270 and APHP-R290-N-300 remain unmapped because the publication does not name them.
Official public support material was checked, but it did not provide a fault-code dictionary we can publish.
Searched Aquatech Solar Technologies’ public product, engineering, FAQ and support material without a login. Aquatech does not publish a separate code dictionary, but the Hydrotherm DYNAMIC/X8 manual names Aquatech Solar Technologies as the warranty and service company and the CER snapshot lists the identical DYNAMIC/X8 model under both brands. That exact twin alone inherits the Hydrotherm codeset; older Dynamic, Flexi, Micra, Rapid, Volt and RS twins remain unmapped because shared ownership and matching registry text do not prove controller compatibility.
Official public support material was checked, but it did not provide a fault-code dictionary we can publish.
Searched exact Aquatherm registry models Dynamic-SS/X8, Flexi-SS/X4, Micra-SS/X2, Rapid-SS/X4, Volt-SS/X6 and RS identifiers across public brand, manual and distributor results without a login. No current official Aquatherm support site, publisher-identifiable manual, or public fault table was located. Similar names and duplicate model strings under Aquatech, Hydrotherm and Ecotherm were reviewed through the duplicate-brand pipeline, but no official ownership or controller statement connects Aquatherm, so no table was borrowed.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Bosch Home Comfort’s public Australian and regional manual libraries without a login. Official Compress 3000 manuals for HP 270-2E 0 FOOV/S and HP 270-1E 0 FOV/S contain 19 actual fault/protection indications across PDF pages 40–41 and 48–49; both manuals were captured, extracted and mapped only to the exact model named by each manual. Codes explicitly marked not used, held-key indications and normal operating states were excluded. A model-by-model mapping review covered all 2 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Chromagen’s public Australian hot-water resource library without a login. The official HP170 V1.3 and HP280 V2.2 manuals contain display-code tables on PDF pages 22 and 20 respectively; 25 fault/protection rows were captured and extracted for HP170 and HP280 and for the exact Midea RSJ model identifiers printed beside those names. LA was excluded from both tables because each manual explicitly describes it as normal and says repair is unnecessary. A model-by-model mapping review covered all 14 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Dux’s public Australian product manuals without a login. The official Ecosmart DHC H4149 Rev. B manual contains six Smart Life app error rows on PDF page 31, and the official Ecosmart Pro-Series H4950 Rev. C manual at https://www.dux.com.au/wp-content/uploads/2024/09/H4950-B-Ecosmart-Pro-Series-270L-manual-2.pdf contains 13 display-code rows on PDF page 40. Both tables were captured, extracted and mapped only to the models named on each manual’s cover. A model-by-model mapping review covered all 37 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Eco Alliance’s current Australian support and warranty pages, public installer libraries, LE-series manuals and exact registry identifiers without a login. A publisher-identifiable Eco Alliance LE-series instruction manual was captured; its cover names ECO-215LEB and ECO-260LS among the covered products and PDF page 13 publishes seven A-series errors. The table was dual-pass extracted only for those two exact registry models. LU models were not mapped because the located manual does not name them.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Ecogenica’s public product, service and indexed manual material without a login. The two original official manual URLs returned 404 on 30 August 2026, so the sources are marked source_moved and their byte-for-byte archived evidence copies remain referenced above with stored SHA-256 fingerprints. The FRE/FREC owner’s-manual snapshot contains 19 text-backed codes on PDF pages 19 and 32, captured and extracted for the six exact EG-215/290/330 FRE/FREC split models and the EG-260FR/FRC all-in-one models it names. The 260/300 W-series manual contains 19 additional alarms as a raster-only table on page 16; its bytes and dual-pass candidates were preserved for EG-260RW and EG-300RW, but every row remains quarantined because PDF.js exposes no literal row anchors. No mappings were inferred for visually similar suffix variants. A model-by-model mapping review covered all 47 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
Official public support material was checked, but it did not provide a fault-code dictionary we can publish.
Searched Edson, Edson Global and every EGS-AIO and EG-AIOHP registry identifier with error-code, fault-code, controller, installation manual and owner manual terms without a login. No maintained official Australian support surface or publisher-identifiable public fault table was located. Marketplace sheets and visually similar generic all-in-one controllers did not document an Edson model scope and were rejected; all six registry models therefore remain identification records without borrowed meanings.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Emerald Energy’s public product-guide and installer libraries without a login. Four official manuals were captured for All-In-One Pro, All-In-One Select, Split System and Split System Pro controllers; 136 fault/protection rows were extracted from PDF pages 22–27, 23 and 46 and mapped to 27 exact registry models or suffix variants explicitly named in those manuals. Reserved driver values, EEPROM-refresh completion and codes expressly labelled not an error were excluded. Emerald’s All-In-One Select data sheet also establishes common app control across the S220, S270 and S320 pairs, supporting HPA1-S320 and HPA1-S320E as compatible mappings. A model-by-model mapping review covered all 46 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
Official public support material was checked, but it did not provide a fault-code dictionary we can publish.
Searched Enviroheat’s public Australian manuals, service pages and exact 200EH1-14, 250EH1-15, EH200M9 and EH330M9 identifiers without a login. The official 2023 EH1 owner manual was captured and reviewed: PDF page 15 says a fault code will appear and tells owners to record it for service, but it publishes no code dictionary. No other official public table was located, so the manual is retained as negative evidence and no codeset was created.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Everhot and Rheem Australian owner, warranty and service material plus exact 251E280 identifiers without a login. The current publisher-identifiable Everhot 251E280 owner and installation guide was captured from Reece’s public document store. PDF page 1 names only 251E280 and page 21 groups thirteen F-series faults by which heating systems remain available. Fd was excluded because it is the normal freeze-protection indication. No older Everhot model inherited the table.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched EvoHeat’s public manuals library without a login. The official Evo 270-1 manual at https://evoheat.com.au/wp-content/uploads/2025/11/MANUAL-Evo-270-1.pdf contains a 14-row P-series and E-series fault table on PDF page 15; it was captured and extracted only for model EVO270-1. The official EVO150-1 manual independently publishes the same 14-entry controller table as EVO270-1, supporting EVO150-1 as a compatible mapping. A model-by-model mapping review covered all 10 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Haier Australia’s public product/manual assets without a login. Official split HP300S2-F7 and monoblock HP200M1-U1, HP250M1-U1, HP200M1U1P, HP250M1U1P and HP330M1U1 manuals contain 55 fault/protection rows on PDF pages 38–39 and 46–47. Both tables were captured, extracted and mapped only to the exact models listed on their covers; similarly named registry variants were not inferred. A model-by-model mapping review covered all 16 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Hydrotherm’s public Australian download library without a login. The official DYNAMIC/X8 GEN6 owner’s manual contains eight display fault/protection rows on PDF page 33; they were captured, extracted and mapped only to DYNAMIC/X8, the exact model named on page 1. Overlapping Aquatech registry labels were not mapped because no located document explicitly identifies controller reuse. A model-by-model mapping review covered all 18 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
Official public support material was checked, but it did not provide a fault-code dictionary we can publish.
Searched iStore’s public downloads and support material without a login. The official 270L R290 Owner’s Manual V1.4 at https://heatpumps.istore.net.au/wp-content/uploads/2025/12/iStore-owners-manual-270-R29-1.3-Jan25.pdf contains symptom-based troubleshooting but no public display-code dictionary; the manual directs users to this official FAQ for further assistance.
Official public support material was checked, but it did not provide a fault-code dictionary we can publish.
Searched Kelvinator Australia’s public user-manual finder, support pages, product identifiers KHPE270362 and KHPE340362, quoted model suffixes, and combinations of error, fault, service and controller without a login. Public material located for the legacy heat-pump range provides owner symptoms and service contact guidance but no manufacturer code-to-meaning table. Search results that reused unrelated air-conditioner codes were rejected, and no code mapping was inferred across A–D or OP2 suffixes.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Midea Australia’s public E-Boost product material and public manuals without a login; the current product page describes an error-code display but did not expose a code table. Official Australian distributor Chromagen publishes HP170 V1.3 and HP280 V2.2 manuals that name Midea models RSJ-15/190RDN3-C, RSJ-23/300RDN3-B and RSJ-23/300RDN3-C on PDF page 5 and contain 25 fault/protection rows. Those Tier-B manuals were captured, extracted and mapped only to those exact Midea model identifiers; LA was excluded because the manuals explicitly call it normal. A model-by-model mapping review covered all 41 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Neopower’s public product and manual pages without a login. Official NA31/NA32 and NA37 manuals contain 16 text-backed display-code rows on PDF page 29, captured and extracted for NA31-210A, NA32-260A and NA37-315A. The official Black Shield manual for NA43-210B, NA44-270B and NA45-320B was also captured and all 47 fault/protection candidates were retained, but its scanned pages expose no PDF.js literal anchors, so those rows remain quarantined and do not render as public codes. A model-by-model mapping review covered all 18 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Priority search of Quantum’s current Australian product, downloads, support and historical manual surfaces was completed without a login. A publisher-identifiable Quantum Energy Technologies owner manual was located in a public manual archive, captured byte-for-byte, and checked on two extraction passes. PDF page 1 names four exact registry models and page 26 publishes seven E-series errors; only those four models were mapped. Later R290, split and other legacy suffixes remain unmapped because family resemblance does not establish the QDC0030PD-11 controller.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Reclaim Energy’s public manual material without a login. The official V2 Installation Manual, Issue 15 contains the controller and PCB error-code table on PDF pages 23–24; its 16 codes were captured and extracted for the 13 V2 models named by the manual. A model-by-model mapping review covered all 73 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Rheem’s public product downloads without a login. The official Ambiheat 571D270 Owner’s Guide and Installation Instructions, Revision 06 lists nine fault codes and source-backed service behaviour on PDF page 28, but no per-code technical causes. Those nine partial rows were captured and extracted only for model 571D270; E09 was excluded because the guide explicitly says it is not a fault code. A model-by-model mapping review covered all 20 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Rinnai Australia’s complete public heat-pump error-code library without a login. Seven official current guides were captured for Enviroflo S 5.0kW, Enviroflo S 7.0kW, Enviroflo AR/GR, Enviroflo A Series, Enviroflo 215L/265L, Hotflo Plus 250L and commercial CHP020/CHP040 products. Their 203 actual fault rows were extracted and mapped only to exact models named in the guides or in the captured S-Series operation manuals; two explicitly reserved 215L/265L values and three commercial maintenance-only alarms that state operation is unaffected were not published as faults. Rinnai’s official GR family page also lists EHPG265VM and directs the GR family to the same AR/GR guide, supporting that compatible mapping. A model-by-model mapping review covered all 66 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
Official public support material was checked, but it did not provide a fault-code dictionary we can publish.
Searched Sanden Hot Water’s public FAQ and Wi-Fi controller support page at https://www.sanden-hot-water.com.au/wifi-controller/ without a login. The controller page describes error alerts and remote fault-finding by authorised installers, but neither official page publishes a code dictionary.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched the former Siddons Solarstream domain, public manual indexes, distributor libraries and exact registry identifiers without a login. A publisher-identifiable MK4068-02B bolt-on owner manual was captured from a public distributor archive. Its cover names four exact registry variants and PDF page 25 publishes PP and EE fault rows; eleven actual faults were dual-pass extracted. EE3 is marked not applicable and the defrost indication is a normal status, so neither was published.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Solahart’s Australian product, warranty and downloadable owner-guide pages without a login. The official 270HAV owner and installation guide was captured; PDF page 1 limits scope to 270HAV and page 27 lists nine fault values. The public guide gives a special reset note for E01 and an operating consequence for P02 but no component dictionary for the remaining values, so their meanings stay deliberately generic. E09 was excluded because the guide explicitly calls it a normal freeze-protection indication.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Stiebel Eltron Australia’s public product and service material without a login. The official WWK 222–302 operation and installation manual names WWK 222, WWK 222 H, WWK 302 and WWK 302 H on PDF page 1 and publishes numeric and E-series fault tables on pages 15–16. Sixteen actual fault rows were captured, extracted and mapped to those four registry models; the manually activated 256 emergency-mode status and additive example values were not treated as independent faults. SHP-O app installer credentials remain restricted and were not inferred. A model-by-model mapping review covered all 11 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
At least one fault-code set has been captured from official public documentation and mapped only to evidenced models.
Searched Thermann and owner Reece’s public Australian product assets without a login. The official current Integrated R290 Installer’s and Owner’s Guide names the 200THC25/P and 300THC25/P families, including -H variants, on PDF page 1 and contains six Smart Life app error rows on PDF page 32. The guide was captured, extracted and mapped only to those eight registry models. A model-by-model mapping review covered all 40 registry models for this sourced brand; every mapping, no-evidence result and controller mismatch is recorded separately.
