Posts Tagged ‘ Replacing ’

I’d like to know if I can replace my 2 wire non digital (hot water baseboard heat, oil fired) thermostat with a 7 day programmable thermostat from Honeywell. I’ve tried looking at the www.yourhome.honeywell.com site but they don’t actually show you how many wires are on the back of the unit I want to install (RTH8500D). I want to buy the item from ebay because I can save myself about half the cost, but I also cannot return it if I buy the wrong thing. Anyone have any suggestions?
