"No call for heat" message Smith GV100

Hi all, just trying to get some clarification on an error message i am seeing on my gas boiler. It is a Smith GV100, 3 zoned system. The burner will ignite for anywhere between 15 and 45 seconds and recycle, sometimes throwing a 2 flash error on the controller, "no call for heat".
I've had a tech come out and check it out and they determined it was a issue with the regulator, so out comes the gas company, nope regulators fine, pressure is fine. So now I'm in a he said/he said situation. From reading other posts here it seems it may be an electrical issue with the TStat, but I am unsure how to verify. Any recomendations?
