The existing room thermostat can be left in place and set to maximum to prevent it interfering with the Tado, or you can remove it and insert a link to join the terminals on the control PCB where the two live switching wires have been removed from.
Do i still need to insert a link as you have...
Thank you very much for helping out, i have a good understanding of what i need to do to get the Tado working now
The whole system is
Elite Cyl Pre-Plumbed Twin Zone 170 L indirect (esppt0170)
im only using 1 zone and its a 2 port valve on it
the 3 channel programmer is a TQX0027, there seems to be only 4 wires coming out off it and wired into the PCB,
It think its basically the same unit as the Esi one
i don't have a frost thermostat fitted
I am only using heating zone 1
My only question would be, where is the fifth wire from the 3...
Advice needed to replace existing 3 Channel WIRED Programmer and Wired Thermostat with a wireless Tado V3+
