Hi John and welcome to the forum. Some things you can try is to cut the wall control wire ends off that hook to the stove. They are week and do not allow signal sometimes. Or, you can just gently lift up on those wires, and it helps sometimes. There is also a wire tie on the wires on the inside of the stove, across from the wall control wires that can be snipped off, as some of them are too tight. Scroll down the forum further, and post on the quad site. Stay in touch. kap

is it safe because stove was running when the therostat was blank house got up to 79 and i had tstat at 74 i dont know if it would ever shut down if i didnt catch it soon as i removed tstat and replaced it back on wall it went into shutdown mode i did what you said with wire conections on stove and wall unit i will have to wait and see if it does again do you think i should call quad and expain how it stayed running i was under the impression it should not run without the wall tstat working thank you for your responce i burn about 4 to 5 ton a year pellets and i already had my fair share of problems i dont want to replace the tstat they change it last year or year before because autoclean door codes

You can tell quad, esp. if you are under warranty. You may need to calibrate the temps on the wall control. They could be off. kap
