2 zone heating again
I have bought a V3 wireless starter kit. I am having to wire it into a Danfoss two port valve system that has 3 motorised valves- Zone 1, Zone 2 and HW. (see photo)
I can see my way to connecting to Zone 1 and HW, (replacing existing Danfoss wired controllers).
If I want to have remote control of Zone 2, what additional kit would I need?
If I just add a wired Tado controller to replace the zone 2 existing controller (battery, so just 2 switch leads running to it), would that work?
If I put in another wireless Tado controller, would I then need a second Tado receiver, as the first only has one heating zone capability? If that is the case, I have seen on this forum mentions of conflicts.

Hi, I have a similar setup, where I was going to loose Zone 2, in my case Zone 2 was the Bedroom areas. This zone 2 valve was connected to a wired thermostat in the main bedroom, so I replaced the wired thermostat with a Tado wired thermostat and added it to the app and called it "Zone 2".
This gave me remote access to Zone 2 via the app. When I want to turn on Zone 2 Bedrooms, I setup Zone 2 to come on which opens the Zone valve in the attic, and simultaneously setup one or all? bedrooms in the app, that you want on at any given time.
That's working fine for me over the past two years.1 -
@AllenB Hello. There are two options to control the second CH zone valve.
- Use a wired thermostat for CH zone 2. It will act as a 'zone controller' for your TRVs (and wireless temperature sensor) that run from the Zone 2 pipework.
- Rewire (in the Danfoss box or at the replaced programmer wiring) and link both zone valves to open at the same time from the CH NO (ON) at the Tado wireless receiver. Use the TRVs (and wireless tempertaure sensor) to control which rooms/rads are heated.

Thank you both for the helpful replies. I will (hopefully) get the system up and running on Zone 1, then maybe consider expanding to zone 2.
