I'm trying to install a TempRite digital thermostat, replacing a 20-some-year-old mercury one. The house runs on a heat pump in the attic, with an A/C unit outside.
Attached is a picture of the old themostat...my problem is, from this picture I'm not sure which wires are supposed to go where on the new stat. I've also attached a page in the new stat's manual which assigns labels to the functions of the old stat's wires (these labels I tag on the wires with stickers).
Based on both pictures, can anyone please take a stab at what labels I might attach to the old stat's wires? Thanks in advance.
