I'll try to keep it short..Girl friend buys stove from dude 3 hours away. When we were there dude had it running in driveway(Slick move..) lookede great, tossed it back back of truck. Installed it and:

1) Wont light itself. Replaced Ignitor, still not heating up. Replaced control board
2) Started up and got to temperature, blower kicked in. Seemed good.
3) Setup Wifi thermostat and here is where my issues started.
a) Set jumpers on J9 to Hi/Low mode - Stove ran until I shut it off with room temp at 74 with Stove Thermostat set at 66.
Control Bd never responded to thermostat tell it too goto low mode.
b) Set J9 to On/Off mode. Stove started and went to thermostat temp before cooling off and going into wait mode.

PROBLEM IS - Stove never restarted. Green light flashing on control bd. Thermostat set at 67, Room was 54 and stove did not startup????

Anyone have any ideas - would appreciate thoughts...

In short, right now stove only lights when you press ON button. Gets to thermastat temperature, then cools itself down before it shuts down - Never to restart again unless you press ON????
 
What kind of thermostat is installed?
One wire or 2 wires?
Sounds like the stat is Bad
 
) Setup Wifi thermostat and here is where my issues started.
If my memory serves that stove is not equipped
For a wyfi stat needs a hard-wired stat of 12 or 24 volts

  • Original System: The pre-2006 Enviro Windsor stoves are likely designed for a simple, millivolt two-wire thermostat system, which acts as a basic on/off switch and does not provide power to the thermostat itself.
  • WiFi Thermostat Requirements: Most WiFi or smart thermostats are low-voltage (24-volt) and require a constant power supply, usually provided by a "C-wire" (common wire). Since your stove doesn't inherently provide this, a direct plug-and-play connection won't work.
