How to install two thermostats to control one furnace?


Currently I have a programmable thermostat on living room, need one more on upstairs bedroom to control in the night. Can two thermostats control one furnace?



Please advice.

you can however whichever one is set higher than its buddy will take priority over the other one. and I wouldn't recommend using two programmable stats together. the honeywell round stats would work just fine
