INSTALLATION

When installing this product

1. Read these instructions carefully. Failure to follow these instructions can damage the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.
3. Installer must be a trained, experienced service technician.
4. After completing installation, use these instructions to check out the product operation.

CAUTION: Electrical Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before beginning installation.

Select Thermostat Location
Select a location for the thermostat about 5ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 1.

• Do not install the thermostat where it can be affected by: — Drafts or dead spots behind doors and in corners.
• Hot or cold air from ducts.
• Radiant heat from sun or appliances.
• Concealed pipes and chimneys.
• Unheated (uncooled) areas such as an outside wall behind the thermostat.

Separate Wallplate from Thermostat

1. Separate the wallplate from the thermostat. See Fig. 2.

Install Wallplate (See Fig. 3.)
Mount the thermostat horizontally on the wall:

1. Pull the wires through the wire hole on the wallplate.
2. Position the wallplate on the wall with the arrow pointing up. Level the wallplate for appearance only.
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and drill two 3/16-in. holes in the wall (if drywall) as marked. For firmer material such as plaster, drill two 7/32-in. holes. Tap the wall anchors (provided) into the drilled holes until flush with the wall.
5. Pull the wires through the wire hole on the wallplate and position the wallplate over the wall anchors.
6. Insert the mounting screws into the wall anchors and tighten.

WIRING

All wiring must comply with local electrical codes and ordinances. Refer to Table 2 for descriptions of terminal designations. See Fig. 6-13 for wiring diagrams for specific equipment applications.

CAUTION Electrical Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before wiring.

IMPORTANT Use 18-22 gauge thermostat wire. Shielded cable is not required.

1. Loosen the screw terminals that are used for the application. Insert the wires into the terminal block and tighten each screw terminal. See Fig. 4.
2. Push excess wire back into the wall opening and restrict wires to the shaded area. See Fig. 5.
3. Plug the wall opening with nonflammable insulation to prevent drafts from affecting the thermostat.

Table 2. Terminal designation descriptions.

Terminal Designation	Description
Rc (see Note 1)	Power for cooling-connect to secondary side of cooling system transformer
R (see Note 1)	Power for heating-connect to secondary side of heating system transformer
y	Compressor contactor
C (see Note 2)	Common wire from secondary side of cooling system transformer
O/B W (see Note 3)	Heat relay or changeover valve terminal for heat pumps
G	Fan relay

NOTES:

1. When used in a single-transformer system, leave metal jumper in place between Rc and R. If used on a two-transformer system, remove metal jumper between Rc and R.
2. Common wire is optional when thermostat is used with batteries.
3. If thermostat is configured for a heat pump in the Installer Setup, configure changeover valve for cool (O-factory setting) or heat (B).

WIRING DIAGRAMS

POWER THE THERMOSTAT

You can choose from three methods to power the thermostat:

• Batteries only (AAA alkaline).
• 24 Vac common wire only.
• 24 Vac common wire with battery backup (AAA alkaline).
  NOTE: Battery backup prevents blank displays during power interruptions.

Wiring 24 Vac Common

• Single-Transformer System—Connect the common side of the transformer to the C screw terminal of the thermostat wallplate. Leave the metal jumper in place between Rc and R.
• Two-Transformer System—Connect the common side of the cooling transformer to the C screw terminal of the thermostat wallplate. Remove the metal jumper between Rc and R.

Installing Batteries
Install two AAA alkaline batteries on the back of the thermostat as marked on the battery holder. See Fig. 14.
NOTE: After the thermostat is mounted on the wallplate, the thermostat does not require removal from the wallplate to replace the batteries. Refer to the enclosed Operating Instructions, 69-1713, for more information on the removable battery holder.

Mount Thermostat to Wallplate

1. Align the four tabs on the wallplate with the four slots on the back of the thermostat. Push the thermostat straight onto the wallplate until it snaps into place. See Fig 15.

INSTALLER SETUP

Configure Installer Setup

1. Enter Installer Setup by pressing and holding the Up and Fan buttons, at the same time, for approximately five seconds, until the screen changes. See Fig. 16.
2. Release the Up and Fan buttons when the display on the thermostat matches the display in Fig. 17.
3. See Fig. 18 to review how the thermostat buttons are used during Installer Setup. See Table 3 for the Installer Setup Numbers and Settings.

THERMOSTAT OPERATION

Thermostat Buttons and Battery Holder
See Fig. 21 for description of thermostat buttons and battery holder.

Display

See Fig. 22 for description of display.

System and Fan Settings

System

• Heat: Thermostat controls the heating system.
• Off: Both heating and cooling systems are off.
• Cool: Thermostat controls the cooling system.
• Auto: Thermostat automatically changes between heating and cooling operation, depending on indoor temperature.

Fan

• Auto: Fan runs only when the heating or cooling system is on.
• On: Fan runs continuously.

Minimum-Off Timer Compressor

Protection
The TH5110 has an adjustable Minimum-Off Timer that can be set from zero to five minutes (Factory Setting— five minutes). The Minimum-Off Timer can be bypassed through the Installer System Test or it can be bypassed permanently by setting the Minimum-Off Timer to 0 minutes in the Installer Setup.
The Minimum-Off Timer is activated after the compressor turns off.
If the thermostat is system powered (common wire), the Minimum-Off Timer is also activated upon initial startup and after power interruptions.
If there is a call for cooling or heating during the Minimum-Off Time, the thermostat flashes ”Cool On” or “Heat On”a. When the Minimum Off Timer expires, ”Cool On” or “Heat On” a appears solid in the display and the compressor and fan turn on.
