Hi, I bought a home. Had no thermostat. Putting in Honeywell CT3500 Programmable. Have Red, Green, Yellow, Blue, White. AC works but no heat.
Thermostat came with R jumpered to Rc. How do I wire this to get AC and heat? Thank you.
I need to also explain that I did put the appropriate wires to their respective
Color coding. My impression is that I am missing a jumper some place.
