Heating not working on 2 zones & classed as 1 zone.
I have just installed my Tado this morning but it is not working as expected.
I have the hot water extension kit & 2 Thermostats. 1 upstairs and 1 downstairs, however when ever I turn heating on downstairs, upstairs come on too. Why would this be?
The Tado walk through set them both up as wireless thermostats, I think this has something to do with it.
Any advise/suggestions would be great.
