Question About Honeywell Thermostat Electronic Programmable Thermostat
New Home- programming?...

We just moved into a new home and we don't have an instruction guide. We've tried to figure it out and think we've programmed it wrong. It is now the middle of the summer and the thermostat is always in the 80's. We are cooking. Please help us. We don't have a manuel. It's number is RTH221B100
