Wallplate installation

1. Separate wallplate from thermostat.
2. Mount wallplate as shown below

CAUTION: ELECTRICAL HAZARD
Can cause electrical shock or equipment damage. Disconnect power before beginning installation.

MERCURY NOTICE
If this product is replacing a control that contains mercury in a sealed tube, do not place the old control in the trash. Contact your local waste management authority for instructions regarding recycling and proper disposal

Wiring

Terminal designations
Thermostat Terminals (connect to network zone panel or EIM)

1. Data communication
2. Power
3. Common

This thermostat does not use batteries. Installing batteries could lead to corrosion of the batteries and damage the thermostat

Thermostat mounting
Once the wallplate is securely mounted on the wall:

1. Push excess wire back into the wall opening.
2.  Plug the wall opening with non-flammable insulation.
3. Align the 4 tabs on the wallplate with the slots on the back of the thermostat.
4. Gently push the thermostat onto the wallplate; the thermostat will snap into place.

Installer setup

Follow the procedure below to configure the thermostat to match the installed heating/cooling system, and customize feature operation as desired

Special function

Auxiliary heat control (Setup Function 26):

• Comfort Setting: The thermostat will prioritize comfort over economy depending on heat pump performance, load conditions and whether the thermostat is calling for the heat pump. Raising the temperature just a few degrees will often activate the auxiliary heat.
• Economy Setting: The thermostat will attempt to reach the temperature setting without activating the auxiliary heat. The thermostat will wait to activate the auxiliary heat depending on heat pump performance, load conditions and how many degrees the temperature setting is changed.

Diagnostic Codes (Setup Function 19):
When Error Codes are present the home screen of the thermostat will display “SERVICE NEEDED” and scroll through all active error codes. Setup Function 19 will display a list of the 10 most recent error codes, both active and inactive. The number on the right of the thermostat will show the number of active and inactive error codes saved in the thermostat. To view the error codes press the up arrow. To clear the list, press and hold both the up and down arrow keys. Active errors can not be cleared; the source of the error must be resolved prior to clearing from the list.
