    Hello all, this is my first post.

    I have a triangle tube boiler that I keep at the appropriate pressure, and most of the time operates well.

    Once in a while like this February day it seems to ignore calls for space heating. Domestic water is fine, just space heating, from the code it appears to believe there is no demand.

    Here in Toronto, there is clearly demand. I believe the wires connected to the thermostat are ok, but if there are any tips to help me determine if that assumption are true or not, or any other tips to force/nudge space heating mode back on I'd greatly appreciate it.

    Thank you
