Hello Coldincanada,
I understand that you're having trouble activating you're heating system. I'm here to help. I've got a few quick questions for you. First off, how many wires are plugged into your Nest thermostat? Which model of Nest thermostat do you have? Oh, and have you tried unplugging the wires and plugging them back in to make sure they're all nice and secure?
I’d look forward to your response.
Best,
Edmond
