Context is below. Thanks in advance for any suggestions.
The problem I'm trying to solve is the radiators heating up when only the hot water has been requested. The circulation pump kicks in either during or at the end of the boiler running to heat the hot water.
The attached photos show that there are two BDR91's and a hot water thermostat transceiver (CS92) installed all pretty close together. I have read they are meant to be spaced further apart to avoid comms problems.
The first move I propose is to completely reset the system and rebind all the elements and see if that solves the problem. If it doesn't, then I'd use my very basic DIY skills to move one of the BDR's along by 30cms in case it's comms interference causing the issue.
Questions
1) Does this sound like the best two steps to take first?
2) Is there an obvious / easy way to tell which BDR is which when I am re-binding them?
3) Do I need to space all the boxes out equally or can I leave the CS92 near one of the BDR's if I go to step 2?
Cheers loads!
Context:
- User (me) is computer tech savvy, DIY basic and heating / boiler numtpy
- Boiler is ~ 20 year old oil fired boiler which has an integral hot water tank and heats the radiators for a fairly big old house in rural France
- Honeywell Evohome was installed ~ 3 years ago by a well meaning heating engineer who was fairly new to connected stuff
- System is very basic - just the old style controller non-wifi (also working as the single room thermostat), hot water controller and tank probe thermostat plus the internet connection from RFG100
- Comms check reports strong signals between all 4 bits of kit (but the DHW comms check reports finding 2 Actuators - see second photo!)
- The engineer left the sticker on one of the BDR's with the wiring option crossed out (no idea if that helps!)
