I have a natural gas boiler and a pellet stove. I have a Honeywell programmable thermostat (2 AAA Batteries) that I have used independently with both of these systems. Switching from one system to the other requires rewiring the tstat. Can a buy some kind of switch, preferably from Lowes or Radio Shack, that I can use to switch which system is being controlled? Preferably something I could put inside of a wall remodel electrical box.
Why? There are a number of variables. I sometimes have lots of pellets or none at all. When it is very cold, I prefer to use both (pellet stove always on), but when it's warmer, just use the stove on the Tstat. Being able to switch without rewiring would be nice!
