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.
Fig. 1. Select thermostat location.
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.
Fig. 2. Separate wallplate from thermostat.
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.
Fig. 4. Insert wires into terminal block.
2. Push excess wire back into the wall opening and
restrict wires to the shaded area. See Fig. 5.
Fig. 5. Restrict wires to shaded area of wire hole.
3. Plug the wall opening with nonflammable insulation
to prevent drafts from affecting the thermostat.
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).

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.
Fig. 14. Installing batteries.
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.

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.
