Title: Wiring can be tricky
Review: I bought this after our county started giving $25 rebates toward programmable thermostats. My old digital (carrier) non-programmable thermostat had 5 wires. I hooked this one up with all 5 wires but found the A/C would not turn on, even after the 5 minute warm up. After reading an Amazon reviewer having a similar problem, I reinserted the RC/Rh jumper and disconnected the blue wire, taping it off with electrical tape. Works perfectly now! This is day two and I am experimenting with the default program mode, which is working fine.I was also worried because the package said it does not work for multi-stage systems. I have a high efficiency gas furnace that is two stage, and it is working normally with this thermostat.
Is the review positive or negative?
