Ideal Exclusive boiler and OT Tado wired.
I have just purchased the Tado and connected to the opentherm connection on my boiler, but it doesn't fire up the boiler, like there is no communication.
My boiler: Ideal Exclusive 2 35kW Combination Boiler Natural Gas ErP - 220480
I have attached diagram or opentherm on the boiler.
I removed the purple jumper cable and connected the wire + and - from Tado to + and - on the boiler.
My old thermostat is a Honeywell one, so right now I have had to connect Tado to just turn on and off the boiler, but I only purchased Tado because of the Opentherm compatibility.
Where am I going wrong pls, pulling my hair out, so your help is much appreciated. Thanks in advance.
