Typical Home Thermostats  
Connect Wires and Mount Thermostat to Wallplate  
Match and connect the labeled wires to the appropriate coded terminal screws on  
the wallplate. (See Figure 4, 5.) Ignore any wires which may be present, but which  
were not connected to the old thermostat.

Refer to the Wiring Diagrams below to be sure your system is wired correctly.  
Be sure to tighten the terminal screws securely, otherwise a loose wire could cause  
operational problems with your system or thermostat.  
Push excess wire back into the hole to prevent interference when installing the  
thermostat to the wallplate.  
Make sure the System Switch is set to OFF, and the Fan Switch is set to AUTO.  
Insert the bottom tab on the thermostat body into the slot at the bottom of the  
wallplate. Press the top of the thermostat body to snap it into the wallplate. Refer to  
Figure 6. (NOTE: Do not force the thermostat onto the wallplate, as the  
terminal pins may be damaged. If it does not snap properly, the thermostat  
may not work.)

Wire Labeling  
Each wire coming from the wall to the existing thermostat is connected to a  
terminal point on that thermostat. Each of these terminal points is usually marked  
with a code letter as shown in Table A below.  
Owners Manual  
Model 44110B  
Note that this thermostat has multiple function terminals that allow Single-Stage  
Heat Pump capability. Standard systems use: Rh, Rc, G, Y, W. [Single-Stage Heat  
Pumps use: Rc, Y1, G, and O or B.] Table A below shows the multiple functions of  
the terminals. Use the terminals that match your system.  
The number of wires in your system can be as few as two (for heat only systems),  
as many as eight, or any number in between. If you follow the labeling procedures  
correctly, you do not have to be concerned about how many wires there are.  
Congratulations!  
Your new Hunter thermostat will provide years of reliable service. By saving energy, your  
thermostat will pay for itself during its first season of use. Thank you for buying a Climate  
Technology product!  
Please read this manual for complete instructions on installing and operating your  
thermostat. If you require further assistance, call Hunter Technical Support at  
1-901-745-9222 from 8am to 5pm Central Time.  
There is often no terminal marking on the existing thermostat of

IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY  
THE SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS  
SHOWN IN TABLE A BELOW. (For example, attach the label  
Figure 5  
Figure 4  
marked W to the wire that goes to the W or H terminal on your existing  
thermostat.) IGNORE THE COLOR OF THE WIRES since these do not always  
comply with the standard.  
After labeling wires, disconnect them from the existing thermostat terminals.  
Remove existing wallplate. To make sure wires do not fall back into wall opening,  
you may want to tape them to the wall.  
Air Purifiers  
CeilingFans  
Humidifiers  
If hole in wall is larger than necessary for wires, seal this hole with insulating  
material so that no hot or cold air can enter the back of the thermostat from the  
wall. This air could cause a false thermostat reading.  
IMPORTANT INFORMATION

2. Temperature Range  
This thermostat can be programmed between 45°F and 95°F (7°C and 35°C).  
However, it will display room temperatures from 30°F to 99°F (0°C and 37°C). “HI”  
will be displayed if the temperature is higher than 99°F (37°C), and “LO” will be  
displayed if the temperature is lower than 30°F (0°C).

Heating  
This thermostat provides a 3.5 minute delay after shutting off the cooling system  
before it can be restarted. This feature will prevent damage to your compressor  
caused by rapid cycling. It does not prevent a rapid compressor restart due to short  
power outages.

4. Battery Warning  
Two fresh AA alkaline batteries should provide well over one year of service.  
However, when the batteries become drained, the Low Battery Indicator will flash on  
the display. When this message occurs, install new alkaline batteries. You have  
approximately 1 minute to change the batteries and keep thermostat’s clock and  
program settings. Once the batteries have become too low to ensure proper  
operation, your system will be turned Off, and the display will be cleared except for  
flashing Low Battery Indicator on the LCD display.

Mount Wallplate and Thermostat  
Remove the wallplate from your thermostat by pressing the release tab on the  
bottom of the thermostat. See Figure 2.  
5-wire Heat/Cool System  
CAUTION: When ONLY the battery icon flashes on the display, the

CAUTION: Do not remove any wiring from existing thermostat before reading  
the instructions carefully. Wires must be labeled prior to removal.

– No Connection  
IMPORTANT! Turn off the power to the furnace at the main power panel or at the  
furnace.  
Figure 3  
Remove existing thermostat cover and thermostat. See Figure 1. Some  
thermostats will have screws or other locking devices that must first be removed.  
Once the wall mounting plate is exposed, look for wires.  
If wires are not visible, they may be connected to the back of the wallplate. Again,  
look for screws, tabs, etc. Some models have doors that open to expose wires and  
mounting screws. See Figure 1.  
NOTE: 5-wire Systems  
If your thermostat has one wire marked R or RH (2, 3, or 4-wire system), then leave  
the jumper wire between the RH and RC terminals on the wallplate. Otherwise, if you  
have separate RH and RC wires (5-wire system), then remove the jumper wire  
between the RH and RC terminals.
