Hello, I'm trying to replace my old DICO Manual Thermostat with a new
Programmable HoneyWell RTH230B. There doesn't seem to be a model,
part, or serial number on the old thermostat, so I can't locate any
information on it via the Web (If you remove the fact place the
following numbers are stamped on the wall plate: 8639 E6 4). At any
rate, there are 4 wires going into the unit from the wall...they are
red, blue, green and white. Can anyone help me figure out which wire
goes to what? Thanks in advance...
Note that color coding assumes that the installer followed the
standards. Many don't. If you aren't sure then check the thermostat
wiring where it connects to the air handler / furnace to be sure.
