Hi, hoping someone can help with another question on a Nest Installation. My son has a Baxi Duo Tec boiler with a wireless thermostat receiver unit next to the mains supply. The mains supply to the boiler passed through the connector plate for the wireless thermostat receiver and supplies the boiler through the LNE wires of a 5 core cable. The two remaining wires went to the COM and CALL terminals of the wireless thermostat receiver.
This has all been removed and the mains supply and boiler supply joined in the L and N terminals of the Heatlink. The switched COM and CALL wires are connected to 2 and 3 in the Heatlink unit. The earth for the boiler is connected externally.
The Nest thermostat is talking to the heatlink and is switching on the heating circulation but the boiler is not heating the water first. Any suggestions why that would be?
Cheers
