Common Questions & Answers About The Honeywell Evohome System
The Honeywell Evohome system uses wireless radiator controllers (TRVs) to manage the temperature in each room or zone. These TRVs are installed on radiators and communicate wirelessly with the central controller, which allows users to set specific temperatures for different areas of the home. The system can be further enhanced with optional room sensors for more accurate temperature monitoring.
Our Gas Safe registered engineers can professionally install and maintain your Evohome system to ensure optimal performance and safety.
Can I control the Honeywell Evohome system remotely?
Yes, the Honeywell Evohome system includes a mobile app that allows users to access and control their heating system remotely. This means you can adjust temperatures, change schedules, and monitor your system from anywhere using your smartphone or tablet, as long as you have an internet connection.
What should I do if my Evohome system isn't responding to schedule changes?
If your Evohome system isn't responding to schedule changes, first check the communication between devices, as this could be due to communication faults.
Verify that all devices are properly bound to the central controller and that there are no low battery warnings on the TRVs or sensors.
You may also need to check the internet connection if using the mobile app to make changes.
Is the Honeywell Evohome system compatible with my current heating setup?
The Honeywell Evohome system is designed to be compatible with most gas and oil boilers, underfloor heating systems, and can integrate with existing zone valves.
It also supports heat pumps and district heating, making it a versatile choice for various heating setups.
Additionally, it supports the OpenTherm boiler control protocol for advanced integrations.
How often do I need to perform maintenance on the Evohome system?
Regular maintenance for the Evohome system includes replacing the TRV batteries every 2-3 years, cleaning the TRV heads annually, and checking the wireless signal strength periodically.
It's also important to update the controller firmware when available, recalibrate temperature sensors if needed, and check the boiler connection annually to guarantee efficient operation.

Common Honeywell Evohome Problems In Sidcup and How To Fix Them

If you're having issues with your Honeywell Evohome smart thermostat, you've come to the right place. Smart thermostats are fantastic for managing your home's heating efficiently, but like all technology, they can sometimes run into problems.
For safety and legal compliance, always ensure work is performed by Gas Safe registered engineers who are qualified to handle gas appliances and controls.
Don't worry, though—we're here to help you troubleshoot and fix these issues with ease. Whether it's a connectivity problem or a device malfunction, we've got the solutions you need. Let's explore some common problems and how to resolve them.
Problem 1: Communication Faults
Solution:
- Check the 'COMMS FAULT' indication on your controller. This means there's a lost signal between the controller and your devices.
- Verify the devices and controller are properly bound. Refer to your Installation Guide for instructions on binding.
- Test the RF signal strength using the 'System test' feature. If the signal is weak, consider relocating the controller or the devices for better reception.
- If interference is the issue, try to identify and remove any sources that may be causing RF interference.
- As a last resort, unbind and rebind the affected devices to restore communication.
Problem 2: Boiler Firing Despite 0% Demand
Solution:
- Check the HR92 TRV valves; they may be slightly open (1-15%) even if the demand shows 0%.
- Manually adjust the valve positions to confirm they're fully closed when heating isn't required.
- Look into firmware updates for your system, which might help address issues with fractional demand display.
Problem 3: Battery and Power Problems
Solution:
- If your evohome Controller has a short battery life when off the charging base, consider replacing the batteries with AA 1.2V Ni-MH 2000-2400mAh.
- For HR91/HR92 Radiator Controllers, replace batteries as needed and watch for low battery warnings on the Controller display.
- Verify the Controller is properly charged using a powered Table Stand or Wall Bracket to maintain peak battery health.
Problem 4: Heating Zone Control Errors
Solution:
- If zones aren't responding to temperature changes or schedules, check the binding between the Controller and zone devices like HR91, HR92, or T87RF.
- Verify that each zone has the correct Heating Type settings configured in the Controller.
- Confirm no accidental pairing of radiator valves to the BDR91 relay has occurred.
- If problems persist, perform a factory reset on the devices and re-pair them with the Controller.
Problem 5: WiFi and App Connectivity Issues
Solution:
- If the evohome app fails to connect or shows maintenance messages, verify your Controller's WiFi settings and network connectivity.
- Check the status of Honeywell's servers, as outages can affect connectivity.
- SSL certificate issues can cause failures; confirm your app and Controller firmware are updated to the latest versions to resolve this.
We hope these solutions help you get your Honeywell Evohome system back on track.
