Relay Not working?

Hi Folks,

I have Tado Room Thermostat and Extension Kit. When I turn on heating on my app, the extension kit sends current and activates both heating and hot water valves. Where it should only activate heating valve. I checked with my old IdealStandard controller and it works properly activating hot water and heating valves separately. So wiring is OK.


Tado extension kit when in app asked for hot water acts OK, activating only hot water valve. Don't know why heating triggers both ... either app is at fault or relay inside extension kit sends current to two channels instead one...
