Thermostat Wiring Issue
Hi Guys,
I am replacing an old Honeywell round thermostat with a Honeywell programmable RH221B. The wires coming from the wall are two sets of red and white wires. One set turns on the heat (fan) when connected together, the other set obviously controls the AC. Nothing happens when touching these two wires together. What would be the correct wiring for these two sets of wires with the same colors? |
