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

You will have to start your own Post, it is against site rules to Hi-Jack and you wont get the correct information
 
just go into this forum and on the top left there is an orange box saying create thread or something like that , and be more precise about what you mean about "not heating the water first" not sure what you are meaning by that

That is all correct what do you mean by not heating the HW first ?
 
As @ianmcd asks, why are you asking about not heating hot water 1st? It sounds like a combi boiler, so heat on demand.
