I have recently gone up the Automated Heating Route, and have upgraded my old Danfoss System to the Honeywell Evohome.
I have set this up with following the Sundial Y-Plan guidelines.
Evotouch Controller running:
Two BDR91 Relays in the airing cupboard (DHW and CH)
CS92A Wireless Sensor on the Hot Water Cylinder
Three Way Valve wired into the relays
8 HR80 Radiator TRVs (in 7 Zones)
- one of these uses a HCF82 Room Sensor (since the Radiator is behind a large sofa)
- one uses the sensor in the evotouch controller, as it is wall mounted in the hall where the old thermostat used to be
- the others use the sensors in the HR80s as the radiators are out in the open so give a pretty fair reading
The above works perfectly.
Boiler fires up when the sensors call for heat.
Using the optimisation on the controller, I am noticing that the boiler is firing significantly less, so am looking forward to a low heating bill this year!
The quandary is with Zone 8 - the conservatory.
I have a HCF82 Room Sensor which is bound to the Zone with no problems
Then I had wired a BDR91 relay module into the pump and valve which are mounted under the conservatory floor.
This replaces a Drayton wireless thermostat and relay which used to be there.
However, I am unable to bind the BDR91 as an Actuator for that Zone.
What am I missing?
I have tried a different BDR91, thinking it was a faulty relay, but that isn't it.
I have also tried an old HC60NG I had - but that also won't bind as an Actuator.
I have tried the reset procedure (holding the bind button for 15 secs) then re-binding but to no avail - the Evotouch Controller just doesn't see it as an Actuator.
I am at a loss on the one, so an advice or recommendations would be much appreciated.
Thanks!
