I've lived in my house for going on 3 years and the pellet stove that came with the house is a Leyden pellet stove by Lopi. I'd like to upgrade the thermostat to a programmable one so it will come on before I get up in the morning. The previous owner had a Robertshaw 9204V simple mechanical thermostat (https://www.amazon.com/ROBERTSHAW-T...s=Robertshaw+9204V&qid=1568699327&s=hi&sr=1-2) that when the temperature reaches below the set temp it would start the stove and it would turn off again once temp was reached. I purchased a Robertshaw 7-day digital programmable thermostat (RS6110- https://www.amazon.com/gp/product/B001DZZNXU/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1). My set up for the old thermostat is just 2 wires, a red RH wire, and a white W wire. When I tried to install those wires on the new thermostat in the same positions, it does not turn on my stove. I put the switches on the back to Non-Heat Pump (vs Heat Pump), and Electric (vs Gas). There was a jumper to the RC slot that I took out, but tried it both ways. Am I missing something? Will this thermostat not work with my pellet stove? The old one is a heat only model. Does the fact that the other one has much more capability mean it won't work? Do I need another wire or some other connection? When I try to increase the temperature so it will kick the stove on, I hear the little click like it should be coming on, but nothing happens. I hooked up the old one and it still works fine, just would love to have this figured out before the weather gets too cold. Answers and advice would be MUCH appreciated on how to install a programmable thermostat to my pellet stove. Attached is a picture of the box of my new thermostat. I'm happy to return it and get something else that works based on suggestions. I chose this one because people mentioned that it had a nice customizable range of the differential temp setting.
