We will not need the jumper from W1 to Y.If there was a thermostat wire from air handler to W1,tape it off. Wire as follows:

OLD-------------------------------------NEW

R------------------------------R with jumper to RC

O ------------------------------O/B

Y--------------------------------Y

G-------------------------------G

C---------------------------------C

W1---(If it had a wire from furnace, tape off)

W2-------------------------------AUX

E----------------------------------E

After wiring we will need to match thermostat to your system, Select the following:

Then you will need to go to the setup menu and set as follows:

0170 - 7

0180- 1

0190- 0

0240- 9

0270- 9

Any other functions are at your discretion.

If any functions listed do not show available, this means thermostat has setup based on a previous selection.
