We've put our heating back on full schedule due to the increasingly colder temperatures. Last season I didn't have our boiler relay set up, however this was successfully set up in Spring and has been working fine since (Apart from one blip where it had to be restarted).
I've increasing noticed that when walking into the garage where the boiler is (Along with the heating relay for the MV) that the boiler is firing (Boiler relay - green light on) when no other BDR91s are open, if I stand and watch it can take anywhere from 30 seconds to 4 minutes perhaps before another relay opens and the heat is released. Whilst this isn't an issue as we have a bypass and a radiator in the garage which is usually open it seems a bit daft that the Evohome controller demands a heat source before opening a zone valve for instance.
I wanted to know if 1) this is normal operation, and 2) whether anyone else has noticed this on their own system.
System set up is:
Boiler Relay
Heating ZV Relay - HR92s on all rads. (Yes I know I technically don't need the ZV however if we ever sell it's easier to revert back)
How Water ZV Relay
Towel Rail ZV Relay
Bypass valve fitted and garage radiator installed before all zone valves.
