Wiring conventional and heat pump systems

2H/1C Heat Pump System TH3210D

NOTES

Wire specifications:
Use 18- to 22-gauge thermostat wire. Shielded cable is not required.

Fan operation settings (TH3110D 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.)

Thermostat mounting

Align the 4 tabs on the wallplate with corresponding slots on the back of the thermostat.
Push gently until the thermostat snaps in place.
Push excess wire back into the wall opening.
Plug wall opening with nonflammable insulation.

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 to change settings.
Press to advance to next function.
Press and hold to exit and save settings.

Setup function	Settings & options (factory settings in bold)
1 System type TH3110D only	1	Gas, oil or electric heat with air conditioning Heat pump (5 minute compressor off time in heating and cooling)
5 Heating cycle rate (CPH: cycles/hour) TH3110D only	5 1 3 9	For gas or oil furnaces of less than 90% efficiency For steam or gravity systems For hot water systems & furnaces of over 90% efficiency For electric furnaces [Other cycle rate options: 2, 4, 6, 7, 8, 10, 11 or 12 CPH]
6 Auxiliary heat cycle rate (CPH) TH3210D only	5 1 3 9	For gas or oil furnaces of less than 90% efficiency For steam or gravity systems For hot water systems & furnaces of over 90% efficiency For electric furnaces [Other cycle rate options: 2, 4, 6, 7, 8, 10, 11 or 12 CPH]
8 Emergency heat cycle rate (CPH) TH3210D only	9 1 3 5	For electric emergency heat For steam or gravity systems For hot water systems & furnaces of over 90% efficiency For gas or oil furnaces of less than 90% efficiency [Other cycle rate options: 2, 4, 6, 7, 8, 10, 11 or 12 CPH]
9 Compressor cycle rate (CPH)	3	Recommended for most compressors [Other cycle rate options: 1, 2, 4, 5, or 6 CPH]
14 Temperature display	1	Fahrenheit Celsius
15 Compressor protection	5	Five-minute compressor off time [Other options: 0, 1, 2, 3 or 4-minute off time]

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.

Troubleshooting

If you have difficulty with your thermostat, please try the following suggestions. Most problems can be corrected quickly and easily.

Display is blank	Check circuit breaker and reset if necessary. Make sure power switch at heating & cooling system is on. Make sure furnace door is closed securely. Make sure fresh AA alkaline batteries are correctly installed.
Heating or cooling system does not respond	Set system switch to Heat. Make sure the temperature is set higher than the Inside temperature. Set system switch to Cool. Make sure the temperature is set lower than the Inside temperature. Wait 5 minutes for the system to respond.
Temperature settings do not change	Make sure heating and cooling temperatures are set to acceptable ranges: Heat: 40° to 90°F (4.5° to 32°C). Cool: 50° to 99°F (10° to 37°C).
"Cool On" or "Heat On" is flashing	Compressor protection feature is engaged. Wait 5 minutes for the system to restart safely, without damage to the compressor.
"Heat On" is not displayed	Set the System switch to Heat, and set the temperature level above the current room temperature.
"Cool On" is not displayed	Set the System switch to Cool, and set the temperature level below the current room temperature.
