Apricus Australia heat pump fault-code guide

The official installation manual cover and specification table identify APHP-R290-260, an all-in-one air-source water heat pump with a 260-litre tank. Record the complete APHP string, serial, installation date and controller photograph. The register also includes APHP-R290-270 and APHP-R290-N-300, but neither is named by this publication, so they do not inherit its fault display. A common R290 refrigerant label or similar Apricus cabinet is product context rather than evidence of controller equivalence.

The specification table describes a built-in touchscreen controller with Wi-Fi, and the controller chapters cover modes, timers, query screens and Smart Life setup. A fault label may therefore be read from the appliance display in a broader interface that also shows ordinary settings. Capture the exact wording and screen state before changing modes. The seven verified entries are descriptive phrases rather than short E codes, so a complete phrase such as Return Air Temperature Fault matters more than trying to invent an abbreviation.

PDF page 37 labels its column Fault Code but displays seven phrases: high-pressure protection, exhaust-gas over-temperature protection, coil temperature fault, ambient temperature fault, hot-water tank temperature fault, exhaust temperature fault and return-air temperature fault. The same table gives possible causes. This catalogue stores the literal line-broken display wording and a stable Fault 1 through Fault 7 route key; it does not fabricate compact codes. Cause summaries remain attributed to the manual, and internal sensor, refrigerant, fan, valve and mainboard diagnosis belongs to a service provider.

Only APHP-R290-260 appears on the Issue 12 cover and specification page. APHP-R290-270 and APHP-R290-N-300 are separate registry identities, and the current product material does not explicitly state that their display firmware and fault table are identical. They remain searchable model pages without borrowed meanings. This boundary also distinguishes the water-heater controller from Apricus pool heat pumps and older solar-hot-water products. Match the plate to a named publication rather than using the Apricus brand or R290 refrigerant as a compatibility shortcut.

Apricus’s Australian site provides service and warranty-request channels, while the current all-in-one product page advertises six years of parts-and-labour coverage subject to its terms. The manual asks owners to contact the service provider if fault guidance does not resolve the issue and limits internal work to authorised people. Before requesting assessment, assemble the model, serial, installation and purchase documents, the complete fault phrase and a photograph of the screen. Warranty duration is product-specific and does not establish that an observed condition is covered.

Issue 12 provides a strong chain from exact cover identity to controller specification and a fault table with possible causes. Each published label was checked against the extracted page twice, and only APHP-R290-260 was mapped. The table sometimes says a later sensor fault has the same causes as fault three; the catalogue preserves that relationship without expanding it into repair instructions. Public evidence does not reveal diagnostic test values, replacement decisions or compatibility for other APHP models, so those matters remain with qualified service and future official sources.
