I received the wrong thermostat. Your customer service did a great job of correcting the error and sent the correct thermostat for next day delivery with a prepaid return pouch.

Ive been using this thermostat with a gas heater because it continues to work during a power failure. When I added a second stove I equipped it with the same thermostat,..good price,,,good service...prompt delivery, and an improved design. Well done!
