New Honeywell Thermostat Installation
We have Concord heat pump in our new home. There was a LuxPro thermostat connected to the system. I purchased a Honeywell RTH7600D in order to have a programmable thermostat.
I replace the old thermostat with the new Honeywell (following the directions of the Honeywell Tstat). When I started it up, the heat only blew cold air.
Here are wires that are present.
Old LuxPro Tstat
E - Black wire that is connected to the W2 terminal
Y - Yellow wire
B - empty
O - Blue wire
W2 - White wire and other end the black wire from E terminal
R - Red wire
G - Green wire
C - Brown wire
The new Honeywell terminals are as follows:
C
G
Y
O/B
RC
R (with a bridge going to RC)
Aux
E
L
The connections I made by following the instructions on the new Honeywell Tstat:
Old Thermostat New Thermostat
E (black wire)--------------------- E (with other end connected to Aux)
Y (Yellow wire)--------------------- Y
O (blue wire)---------------------- O/B
W2 (white wire)------------------- Aux (along with other end of E wire)
R (red wire)------------------------ R
G (green wire)--------------------- G
C (brown wire)--------------------- C
I let the hat pump run all afternoon to see if it would start blowing out warm air but no such luck
Any ideas?
Your help is much appreciated!
