Tado X Wireless Install - hot water works, but not heating

RajR34

Hello all,

I have just installed a Tado X wireless thermostat and only the hot water function seems to be working - I have no heating working.

I have a conventional Bosch Greenstar 24i System mkIV boiler with a hot water tank in the loft.

I have had/have Horstmann Centaurplus C27 series 2 programmer, and a horstmann thermostat.

Not sure if it makes a difference, but I have a wired thermostat currently and going to wireless (see below, I've bridged some wires as I believe this is what I have to do?)

Ive attached some images of how I've wired the programmer,

Old wiring

New wiring

and also the existing thermostat (I have bridged the black wire and the grey wire).

Any help would be greatly appreciated - it feels like I'm almost there??

Also, I have a 4 month old baby in the house so no heating is far from ideal (don't worry we have an electric heater the heats bedroom!)

I think I've fixed it! I think I bridged the incorrect wires on the existing thermostat.

I've since changed the bridged wires to the brown and grey wires and I can feel the radiators getting hot at the bottom :)
