Hi there,
I need to have a second (just heat) thermostat connected to my Armstrong SX-80 furnace.
There is a basement suite tenant living in my house, so we need to be able to have her turn on the furnace when she arrives home independently of the main thermostat upstairs.
The house is A/Ced so the thermostat upstairs is integrated with the A/C.
The one for the basement.....I tried bypassing just the 2 wires leading from the furnace and connecting them to fire it up, but it would not work that way....
What is the way to do this please?
Thanks,
Gordon
