Installing Tado Wireless Thermostat into a 2-zone heating system
I have searched through the forums to see if a previous post exists regarding my set-up, but to no avail. Apologies in advance if I have missed it though!
I recently purchased a Tado Smart Thermostat Starter Kit V3 and am looking at the option of self-installing this but I was hoping for some advice on the best way to achieve this.
My Current Set Up is as follows:
Boiler: Valliant Home Combi 35 (no separate hot water cylinder)
Thermostat: 2 x Honeywell CM907 Thermostats, one currently located on the Ground Floor hallway (wired) and the second in the master bedroom, again wired. Each thermostat is linked to a zone valve so we have two heating zones
Wiring Box: Danfoss WB12, the thermostat cabling, zone valves and boiler wiring are hooked up to this wiring box in the airing cupboard.
I wish to replace my downstairs thermostat with the Tado wireless thermostat to control the downstairs zone. At this moment in time, I wish to retain the upstairs CM907 and eventually replace this with a wired Tado thermostat to control the upstairs zone.
In saying this, I am happy to temporarily compromise and run the whole system off the wireless thermostat and override the zone valves if needed.
I was hoping if anyone could provide advice on the best way to install this. I have attached photos of the wiring of the WB12.
Many thanks in advance.
