I need help replacing my existing thermostat with the Honeywell T8611G
Chronotherm IV thermostat.
Here is my existing system:
Heatpump system with 2 heat/1 cool.
2 1/2 tons Philco (Nordyne) heatpump, 10 SEER
thermostat Robertshaw 300-208 with auto changeover but not
Here is the existing wire connection with the Robertshaw including the
color for anyone familiar with the color code:
White wire connects to the Rorbertshaw's W1
Yellow wire connects to Y1
Green wire connects to G
Orange wire connects to O
Brown wire connects to 24v common
Red wire connects to 24v hot wire and connects to R
Now, here are the connecting points I can find in the Honeywell T8611:
C, Y1, G, O/B, E, W2, W1, R, X1, X2, L, OT, OT.
I'm thinking of connecting the Honeywell as follow:
white = Honeywell's W1
yellow = Y1
green = G
orange = O/B
brown = C and X1 (??)
Red = R
Please let me know if this is the right connection before I try and
fry my thermostat :). If there is a change, please let me know as
Please send me a copy of the reply as well as I don't read this
often, at email@example.com
Thank you very much.
