Any milivolt thermostat will work. The stove you have is made by Heatilator.
There are lots of Honeywells, Lux's, Hunters, etc that will fit the bill. Also some remote options. Skytech makes a good t-stat (remote) The one thing to look for in a good unit, is a "Swing". An adjustable swing is very important with a Heatilator/Quadrafire stove.
Example : A standard stat may have a 1° swing (if set at 70°, it will kick on at 69° and shut off at 71°) But a good stat will have an adjustable swing up to 3°-4°… or if set at 70°, it will kick on at 68° and off at 72° / 2° swing.
So choose wisely. A small swing will cause short cycles. And that is not good on the unit.[/quote
I use the one that came with the stove, Lux mechanical, $10 online. PSM30SA
Yes on cycle
What is your anticipator set at on your thermostat that you got with the stove? Wondering if I need to adjust it.
