I have seen several people tell people that they need a millivolt thermostat. A millivolt thermostat works with a standing pilot gas valve system. Several thermocoulpes in series generate a voltage while sitting in a pilot flame. It works like the thermocoulpe in some stoves work to prove a fire is established. They usually make .75 volts. So a milivolt thermostat is designed for millivolts not 24 volts ac like my quad uses in its control circuit. I have never seen a pellet stove with a standing pilot light. Are there any stoves that the manual specificly requires a millivolt thermostat?
