    2 zone thermostat
    I am looking for a compatible digital thermostat for my system. It is a trol a temp system from 1989. One blue one white one red wire. It is a power on and power off system. I need power to open the damper using red and white while opening it kicks on the furnace. Power then goes from white to blue to close damper while closing the furnace is kicked off. Have thought about using a relay to make this happen but would like a thermostat that could take care of the problem. Wires were labeled 4 5 and 6 honeywell told me they represented r w y but they were wrong.

Programming 3 zone thermostat [ 3 Answers ]

I have a multi level home, and it's set up in 3 zones so I can set my thermostat for each zone, up to 4 periods per day, for the whole week(HVAC tech says they now claim this method really doesn't save $). We are comfy at 68 for heat, so if other zones aren't being used for a period, what is...
