I have more than 30 year old gas furnace made by "Day & Night". I need to replace the old Robertshaw thermostat, which controls gas furnace and air conditioner.
I ordered Honeywell digital thermostat "Focuspro 5000 Non-Programmable Thermostat", and I want to use C wire to power the thermostat instead of the battery.
On the gas furnace control panel, I have terminals like
C/X R/4 W G Y.
My question is Can I use the C/X terminal on the gas furnace for C line to the thermostat to power the thermostat? I do not know yet if there is a C line on the old Robertshaw thermostat. If there is no C line, I can run a cable myself from the this C/X to the thermostat if this can be used for C line.
Thank you very much.
