Thermann heat pump fault-code guide

The Integrated R290 guide says the model and serial number are on the compliance plate on the outside of the water heater. Copy the full 200THC25 or 300THC25 identity, including P and -H where present. The cover explains that -H has a model meaning and that plug-in availability differs, so those characters should survive lookup even when the same app codes are shared. Keep the plate readable and photograph it with proof of installation. Thermann also has other heat-pump ranges; an Integrated R290 plate is the evidence required before using this specific Smart Life namespace.

Thermann documents a physical controller display with automatic locking, operating symbols, temperature and timer behavior. It also explains pairing the water heater with the Smart Life app, which can surface device information and errors remotely. When reporting a problem, say whether the message appeared on the appliance or in the app and capture both if available. A flashing fault symbol on the controller supplies context even where the app carries the actual error text. Wi-Fi configuration is an owner feature, but removing controller covers, accessing wiring or servicing refrigeration remains work for authorised trades.

The six publishable Thermann error rows appear in the Smart Life app material on PDF page 32 of the captured Integrated R290 guide. They are stored as an APP namespace rather than being represented as generic controller-display codes. That preserves where an owner actually encounters the message and prevents confusion with normal icons or timer text on the appliance. Copy the app value exactly and pair it with the compliance-plate model. The source’s troubleshooting and refrigeration sections contain technician material, so this guide limits owner advice to evidence capture, safety and the official support handoff.

The source explicitly names eight Integrated R290 combinations across 200THC25 and 300THC25, including P and H forms. Those units share the documented controller and Smart Life error set. Thermann’s current range also includes a Split Heat Pump, and historical Thermann X products have separate product and safety documentation. No captured statement maps those other controllers to page 32 of the Integrated guide. The site therefore treats the Integrated family as one exact source scope while leaving other Thermann registry models unmapped until their own public code evidence is captured. Brand ownership through Reece does not establish electronic compatibility.

Thermann’s official contact page accepts product enquiries and links owners to Reece stores for in-person assistance. The Integrated guide’s warranty process asks for the serial and model from the outside compliance plate, contact information and proof of installation date, and warns that non-covered work can result in service costs. Begin with the installer or Reece/Thermann channel shown on the purchase paperwork, carrying the plate image, app screenshot, installation evidence and symptom description. Let that channel identify the authorised agent and applicable terms instead of booking unapproved internal work on the assumption that an app error guarantees coverage.

The captured Reece Group publication gives the Integrated R290 family strong public coverage: exact model scope, outside compliance-plate location, controller lock behavior, Smart Life setup, six app error rows and warranty steps. Thermann’s live site supplies current brand and contact routes. The record does not show that Thermann Split, recalled Thermann X equipment, gas products or other storage ranges use these app meanings. It also does not convert installer and refrigeration sections into DIY guidance. Public pages stay limited to the eight named models, while other Thermann owners receive honest coverage status and the Reece-backed support route.
