Step-by-step fix guide | Honeywell Home heating controls
This guide is for evohome owners whose Honeywell Home HR92 radiator controller won’t bind. The steps follow the evohome installation guides and wireless binding guide from Resideo, which makes Honeywell Home products.
What This Problem Means
The HR92 works through continuous 2-way communication with the evohome controller, so it has to be bound to it first. Resideo says a successful bind shows a SUCCESS message on both the evohome controller and the radiator controller.
Common Symptoms
- No SUCCESS message on the evohome controller or the HR92
- The HR92 shows UNBOUND
- The zone name doesn’t appear when you press the HR92 button
- A low result in the RF check
Safe Checks You Can Try
1. Set up the controller side, then bind the HR92
First set up the controller side. For a new zone, Resideo’s evohome installation guide says to press and hold Settings for 3 seconds, press the green tick, press ADD ZONE, type a name for the zone and press the green tick, then press RADIATOR VALVE on the evohome Controller. To add a radiator controller to an existing zone, it says to press and hold Settings for 3 seconds, press the green tick, press ZONE CONFIGURATION, select the zone and press RF DEVICE BINDING. Then, on the HR92, press the button once; it should say UNBOUND. Press and hold the button for a further 5 seconds until it says BIND. Press the button once; it should say BINDING. Resideo’s evohome installation guide has the full binding sequence.
2. Look for SUCCESS on both units
You should receive a SUCCESS message on both the evohome controller and the radiator controller. If not, go back and re-bind.
3. Check the zone name
After binding, press the HR92 button: Resideo says the name of the allocated zone should appear on its display.
4. Repeat for each radiator controller
Resideo says you must repeat these steps for each radiator controller.
5. Test the signal
Resideo’s guides give two signal checks: RF COMMS CHECK in the evohome controller’s installer menu, and RF CHECK on the HR92 (turn the dial to display RF CHECK). Results run from 1 (poor) to 5 (excellent); 0 means the radiator controller has not received a test signal from the evohome controller. The HR92 test exits automatically after 10 minutes.
6. Allow a few minutes
Resideo says battery devices only communicate with the evohome controller every four minutes to save power.
7. Check your evohome controller
Resideo’s UK installation guide lists the HR92 for the evohome Controller (ATC928). Its guide for the newer evohome R3 controller, published for EMEA, says the older HR92 and HR91 controllers will not work with that version of evohome controller.
