 |  "Changing Honeywell Chrono ThermIII to RTH7400"
, posted Thu 31 Jul 18:07  
Hi,
I need to change out my old thermostat (Honeywell Chronotherm III to a RTH7400). Not sure whether to follow the Coventional or Heat Pump wiring instructions. My current system is a Heat/Cooling system (Gas Heat, Electric cooling), with an auxillary or emergency heat (electric). The wires I have are as follows:
R
C
O
Y1 & W1 ( one wire connected to both with a bridge)
E
W2
G
It seems like the instructions are telling me to follow the Conventional, but all the wires don't match.
Thanks in advance for the help!
