Common Questions & Answers About The Honeywell Evohome System
The Honeywell Evohome system can control up to 12 heating zones and 1 hot water zone. This allows you to manage the temperature in different areas of your home independently, providing customised comfort and energy efficiency.
What should I do if I encounter a “COMMS FAULT” error on my Evohome system?
A “COMMS FAULT” error indicates a loss of signal between devices in the Evohome system. To resolve this, check the placement of your devices to verify they’re within the typical RF range of 30 metres from the controller.
If necessary, relocate devices closer to the controller. It’s also useful to perform RF signal strength testing, especially in larger properties, to identify areas with weak signal strength.
Can I extend the wireless range of the Evohome system with extenders?
No, the Honeywell Evohome system doesn’t support wireless range extenders. The components communicate using an 868MHz RF signal with a typical range of 30 metres.
If you’re experiencing signal issues, consider repositioning your devices or the controller to verify effective communication within the property.
Is the Evohome system compatible with all types of heating systems?
The Evohome system is compatible with most wet central heating systems, including combi boilers, system boilers, and heat pumps.
It can control both radiators and underfloor heating, making it versatile for various heating configurations.
How can I control the Evohome system remotely?
You can control the Evohome system remotely using the Total Connect Comfort (TCC) app. This app provides access to your heating controls from anywhere, allowing you to adjust settings, view system status, and receive alerts.
Additionally, the system can integrate with voice assistants like Google Home and Amazon Alexa for hands-free control.
For optimal performance and safety, all installations are completed by our Gas Safe registered engineers with extensive experience in smart heating systems.

- Verify that the Thermostatic Radiator Valves (TRVs) are opening and calling for heat properly.
- Make sure the boiler itself is functioning and has an adequate power and fuel supply.
Problem 3: Incorrect Temperature Readings
Solution:
- Calibrate the internal temperature sensors in the Evohome controller to make sure accurate readings.
- Relocate the controller away from any heat sources that may affect temperature readings.
- Regularly clean dust and debris from the sensors on the radiator controllers.
- Replace any faulty temperature sensors in the radiator controllers if needed.
- Consider the heat from nearby electronics when placing sensors to avoid skewed readings.
Problem 4: WiFi Connectivity Issues
Solution:
- Update your Evohome controller to the latest firmware version to make sure peak performance.
- Move your WiFi router closer to the Evohome controller to improve signal strength.
- Double-check that the correct WiFi network name and password are entered in the system.
- Reset the network settings on the controller and attempt to reconnect to the WiFi.
- If necessary, use a WiFi extender to boost the signal to the controller’s location.
Problem 5: Radiator Controller Problems
Solution:
- Replace the batteries in the radiator controllers when they’re low to maintain functionality.
- Re-bind the controllers to the Evohome system if the connection is lost.
- Clean the valve pins and make sure they operate smoothly for effective control.
