Hello. The problem goes like this. The call light (I believe it is called the Thermocouple Light in the literature) doesn’t come on when the room temperature drops to the set point on the thermostat. The stove remains down, as if it has no power. When I disconnect the stove from the power source and then reconnect the power the stove comes up and runs properly, however the call light still doesn’t come on. I replaced the Control Box (The process controller) at the start of the heating season. I have no idea why the Controller was bad, the stove had been setting idle for the summer, but the stove has been operating properly until now
