Good morning,
I was wondering if anyone may be able to assist me- My current system is an S Plan design with two Honeywell valves, hot water cylinder and Viessman 100 boiler. Current controls is a Salut IT500 wireless thermostat
Am going to convert to the full Evohome system- Hot water kit, HR92s on all rads, Opentherm Bridge. I am going to manually lock open my CH valve and keep my two towel rails with standard TRVS to allow them to heat up when the hot water is on (The wife will be pleased).
Couple of questions.
Can the BDR for the hot water be swapped over with the wiring in my current controller? But currently valve opens first on the current setup then boiler/Pump- does this need to be re-configured to get the boiler to fire?
Opentherm- This is where i am most confused- will it call for the boiler to fire up? As in the product description it says:
"Wireless OpenTherm Bridge (R8810) is a replacement of the BDR91 Wireless Relay Box".
Therefore to get my boiler on for CH do i need a BGR91 or will the Opentherm do the job?
The online course gives no mention of the Opentherm Bridge in the setup
Any help would be much appreciated
