Need help with V3 Wired Thermostat - can't get to work with underfloor heating system
Hi,
We are trying to replace a old wired thermostat with this wired tado thermostat. The boiler and underfloor heating is in a single room (and only heating this room).
Old thermostat: ZL-2056
Boiler: Valiant Ecotec plus 825
Waterline control centre ZL-3347-03
We've used the app for instructions to wire the tado thermostat using the existing wires from the old thermostat but it just doesn't turn the pump on. Will the tado thermostat even work with this current system? Any guidance on this would be massively appreciated.
Below is a diagram we've used for the current system:
