Two Zone heating
I am a bit stuck with a setup and wonder if anyone can help please.
We have a house which is divided for heating in two, main house and basement. The heating is served by one boiler with two zones, each zone controlled by a motorised valve. The main house has a basic tado installation configured for the heating only. The hot water is on a separate controller and boiler. The basement wasn't ready for heating until now so we have purchased a tado wireless extension kit (a thermostat) for the basement.
Can you anyone help with the wiring setup? When the controller in the main house calls for heat we want the valve to open for the house which it is doing now, when the basement controller calls for heat we want the valve to open for the basement. Finally when both main house and basement are calling for heat both valves would open.
I have attached a couple of pics showing the current setup...
Any help would greatly be welcome
