Hello,
I just installed google nest learning thermostat, thermostat is successfully connected to heat link, and when I turn thermostat it self I hear click in heat link. The boiler is around 1 year old called EcoTec pro VC 246/5-3 E. There was a 5 wired cable from old thermostat to boiler, I cut it in half to fit heat link in between, grey and black wires I connected like shown in the instruction, and gave a power to heat link. Another half of 5 wired cable that goes into boiler is connected to heat link as shown in instruction. So when I turn this system on and the temperature hits asked temperature, boiler is not turning off, but continues to heat. I assume that the problem is on this 5 wired cable that is going to boiler it self, because only 2 wires of this cable are connected (in heat link). But in boiler these 5 wires are used. I did a normal trouble shooting, restarting system, resetting thermostat, changing different pro modes in thermostat it self, googled for known solution but nothing ever helped. Can someone help me trouble shoot this problem?
Kind regard, Ilya
