Wallplate installation

Remove the wallplate from the thermostat as shown at left, then follow the directions below for mounting.

1.  Pull wires through wire holes.
2.  Position wallplate on the wall, level, and mark hole positions with a pencil.
3.  Drill holes at marked positions as shown below, then tap in supplied wall anchors.
4.  Place wallplate over anchors, insert and tighten mounting screws.

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

Fan operation settings

TH2110DH/TH1110E1/ TH1110DH 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 pump 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.)

Set fan operation switch.

Thermostat mounting
Align the 2 tabs at the top of the wallplate with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place.

Settings are the same on
TH1110E1 & TH1110DH models.
TH1110E1 has a larger display.

Installer setup

Follow the procedure below to configure the thermostat to match the installed heating/cooling system, and customize feature operation as
desired.
To begin, press and hold the   and buttons until the display changes.

Press the or button to change the setting.
Press the and buttons simultaneously for one second to advance to the next function.
Press and hold the and buttons to exit and save settings.
NOTE : If you do not press any button for 60 seconds while you are in the setup menu, the thermostat automatically saves any changes
made and exits the menu.

CAUTION: EQUIPMENT DAMAGE HAZARD
Compressor protection is bypassed during testing. To prevent equipment damage, avoid cycling the compressor quickly.

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.

Accessories & replacement parts
Please contact your distributor to order replacement parts.
**Cover plate assembly** ……………………………………….. Part Number 50002883-001
Use to cover marks left by old thermostats.
