Sorry....yet another diy install thread for evohome. I think I have been thinking too much about it and have got myself confused so any help is much appreciated.
We have moved to a victorian house which currently has 2 single zone Honeywell wireless thermostats installed linked to 2 BDR relay box which control the 2 zone valves (upstairs and downstairs).
Our hot water is provided by a Vitodens 100W 26kw boiler and an unvented system. There is a zone valve for the hot water which is controlled by a Channel H37XL controller (2 CH and 1 HW).
We have some rooms which are being heated during the day - and do not need to be - so I wanted to install some TRV's to do this - hence evohome.
I have ordered an essential kit (Evohome controller, BDR1 and 6 TRV's alongside a hot water kit). I will get more TRV's over time.
When I install evohome I assume I can replace the Channel H37XL with the BDR1 relay, and then reprogram the 2 CH zones BDR relays to be controlled by the Evohome controller?
Or does the BDR1 evohome relay control the HW and both CH zones?
Where does the HW kit fit into this - I was going to install the thermostat in place of the current one on the boiler, and then wire the controller and valve into the system.
Is this correct or should I just leave the Channel H37XL in place, turn it to be permanently on, and then ignore the BDR1 that comes with the evohome kit and just install the hot water kit?
When/if I remove the current Channel H37XL controller, which wires (L,N etc) do I connect as I believe I would need to make this be permanently on?
As you can see I have really confused myself.....
Thanks in advance
