Honeywell RTH221 thermostat is set @ 74 degrees at night, but only goes to 72.
I have a honeywell RTH221, I run the schedule wake, sleep and leave. I want my temp set at all around 73 degrees and for some reason dips to 62 degrees in the middle of the night before turning on again, during the day it drops from 73 degree dipping to 67 degree before turning on again! Is that how it's programed??

I just installed a Honeywell RTH221 Thermostat. The old one had a red, green, yellow, and black wires. I installed the black one to the yellow connection. Now the unit runs backwards... heat instead of cooling... cooling instead heating. How should I have connected the wires?
