Thermor Appliance Repair in Exwick

What does error code W.29 mean on a Thermor heat pump water heater?

Error W.29 indicates the compressor discharge temperature is too high, exceeding 110°C. This can be caused by a sensor drift, lack of refrigerant, compressor issues, or installation problems. Contact a qualified heating engineer to check the evaporator cleanliness, refrigerant charge, and air circulation.

What does error code 3 or W.23 mean on a Thermor electric water heater?

Error 3, W.3 or W.23 indicates a water temperature control fault related to a temperature sensor anomaly. This stops heating to prevent abnormal temperature rises. Restart by cutting power for 30 seconds. If the error persists, a qualified engineer needs to inspect the temperature sensor.

What does error code Err10 mean on a Thermor electric radiator?

Error Err10 indicates a communication fault between the motherboard and thermostat control. Cut power for 2 minutes, then restart. If the error persists, contact your installer or a qualified engineer as this indicates an internal electronic fault.

What does error code W.30.3 mean on a Thermor heat pump water heater?

Error W.30.3 indicates a component is in auto-conduction, showing high intensity on the electrical line. This relates to internal electronics. Switch off the unit and contact a qualified engineer immediately. Do not attempt to repair electrical components yourself.

What does error code W.21 mean on a Thermor heat pump water heater?

Error W.21 indicates the outdoor or air inlet temperature sensor is reading abnormally. Check the connections and positioning of the air temperature sensor and verify its ohmic value. If the error persists, a qualified engineer will need to replace the sensor.

What temperature should I set my Thermor electric radiator to?

The recommended temperature for living areas is 19°C, and for baby rooms 18°C. The Comfort temperature can be set from 12°C to 28°C on most models. For bedrooms, a slightly lower temperature of 16-17°C is often more comfortable for sleeping.

What should I do if my device won't connect to Cozytouch?

Check that your network is functioning correctly and that you are using 2.4GHz Wi-Fi (5GHz is not compatible). Ensure there are no firewall restrictions, check the distance from your router, and verify there are no physical obstructions blocking the signal.

Is the Cozytouch app free to use?

Yes, the Cozytouch application is completely free to download and use. There are no subscription fees.

What is the difference between inertia radiator heating body materials?

Aluminium heating bodies are highly reactive, ideal for irregular schedules with variable occupancy times. Cast iron bodies offer both inertia and reactivity, suitable for mixed routines. Heat transfer fluid bodies provide steady, sustained warmth best suited for regular schedules with consistent presence times.

What is the pilot wire on Thermor electric radiators?

The pilot wire (fil pilote) allows centralised control of multiple radiators from a single programmer or energy manager. It transmits operating commands including Comfort, Eco, Frost Protection, and Off modes. All radiators with pilot wire capability follow the same protocol, enabling whole-home heating management from one controller.
