Read these instructions carefully. Failure to follow these instructions can damage the product or cause a hazardous condition.
Wallplate installation
Remove the wallplate from the thermostat as shown on the left, then follow the directions below for mounting.
- Pull wires through the wire hole.
- Position the wallplate on the wall, level, and mark hole positions with a pencil.
- Drill holes at marked positions as shown below, then tap in supplied wall anchors.
- Place the wallplate over the anchors, and insert and tighten the mounting screws.
CAUTION: ELECTRICAL HAZARD
Can cause electrical shock or equipment damage. Disconnect power before beginning installation. Drill 3/16″ holes for drywall. Drill 7/32″ holes for plaster.
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 the Thermostat Recycling Corporation at www.thermostat–recycle.org or 800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.

Wiring guide — conventional and heat pump systems
NOTES
Wire specifications:
Use 18- to 22-gauge thermostat wire. A shielded cable is not required.
- Power supply. Provide disconnect means and overload protection as required.
- Remove jumper for 2-transformer systems.
- Optional 24 Vac common connection
- The common connection must come from the cooling transformer.
- Use either O or B terminals for the changeover valve.
- Use a small piece of wire (not supplied) to connect W and Y terminals.
- Set the fan operation switch to Heat Pump (see page 5).
Fan operation settings
TH2110DV/TH1110DV only:
- Gas or Oil: For gas or oil heating systems, leave the fan operation switch in this factory-set position. (This setting is for systems that control the fan in a call for heat.)
- Electric or Heat Pump: Change the switch to this setting for heat pumps or electric heat systems. (This setting is for systems that allow the thermostat to control the fan in a call for heat if a fan wire is connected to the G terminal.)
Thermostat mounting
Installer setup
Follow the procedure below to configure the thermostat to match the installed heating/cooling system, and customize feature operation as desired. Function number
Setting To begin, press and hold the 
AND 
buttons until the display changes.
- Press the or button to change the setting.

Special functions
Early Start (Setup Function 13): Early start allows the heating or cooling to turn on before the program start time, so the temperature is reached at the time you set. Compressor Protection (Setup Function 15): Forces the compressor to wait a few minutes before restarting, to prevent damage. During the wait time, the message Cool On or Heat On (heat pumps only) will flash on the display.
