NOTICE OF CAUTION! DO NOT disconnect  
the wires from the existing thermostat  
before reading these instructions. The  
wires must be labeled prior to removal  
to ensure proper connection.

UNINSTALLING THE EXISTING UNIT  
. Turn the system power OFF at the existing thermostat. Turn the power to the  
1
HVAC system OFF at the main power panel or at the furnace.  
(
Failure to turn off the power to the existing thermostat before removal could damage your  
system.)  
2
. Remove the existing thermostat cover to access the wires from the wall. (Some  
thermostats may have multiple covers, screws or other locking devices that must  
be removed or disengaged.)  
3. Locate, but do not disconnect the wires.  
(
If wires are not visible, they may be connected to the back of the wall plate. Some models may  
have doors that open to expose the wires and mounting screws.)  
4
. Do not let the wires slip back into the wall during disconnection. You may want to  
secure the wires to the wall as you disconnect them. After all wires are labeled,  
disconnect each wire and remove the existing wall plate. (Any unused wires  
should be capped with an approved electrical connector, such as electrical tape.)  
4

44002-01 r051807

5. Using the provided stickers, label each wire according to the chart.  
If the terminals are not labeled, contact a qualified HVAC technician.  
NOTE: Wire colors do not always comply with standards; therefore, wire color should be ignored.  
Refer to the existing terminal designation for proper identification.  
If wires marked “Y” or “C” are both present, “C” may be a Common wire and provides 24 VAC  
power to the unit. Connecting it greatly extends battery life. If there is no "C" wire, the thermostat  
will run on battery power.

from the back of the thermostat.  
2. Position the new wall plate on the wall horizontally and pull the labeled wires  
through the opening.  
3
. If the existing holes do not match those on the Hunter thermostat wall plate or, if  
there are no existing holes, visually level the wall plate and mark the wall for two  
holes.

NOTE: A jumper wire is provided, connecting the RH and RC terminals for systems that do not have  
both an RH and RC wire. If you have both an RH and RC wire, remove this jumper; otherwise, leave  
the jumper in place.  
2
. Complete wiring diagrams for Conventional HVAC Systems and Heat Pump  
Systems are provided on pages 72-74. Match and connect the wires from the wall  
to the terminals as shown. Insert wires behind the black terminal shield. Tighten  
each screw after the connection is made.  
3
. Wrap the ends of any extra wires individually in electrical tape and carefully push  
them into the wall. Push any excess wire length back into the wall to prevent  
interference.

2. Place the thermostat over the wall plate, aligning it over the terminal and battery  
openings. Press the thermostat to the wall plate and it will snap into place.  
NOTE: Do not force the thermostat onto the wall plate as this may damage the terminal pins. If the  
thermostat does not snap into place easily, the unit may not work.  
3. Restore power at the electrical panel and/or furnace.

GENERAL OPERATING INSTRUCTIONS  
Your new Hunter thermostat is easy to program and use. The front of the thermostat  
is a touch screen that responds to the pressure of a finger.  
You can program the thermostat to automatically readjust the temperature and  
airflow to settings that you choose or you can use the pre-programmed default  
settings. You can also operate the thermostat manually.

SETTING ThE SPAN  
The SPAN setting mode in the SYSTEM SETTINGS MENU allows you to adjust the  
system ON/OFF cycle rate. The default setting is 2F. The system cycles ON or OFF  
when the temperature is within 2°F (1°C) above and below the set temperature. The  
span setting can be adjusted if your system is cycling too fast or too slowly.  
Setting a higher SPAN number increases your cycle time by allowing the system to run  
longer; a lower number will decrease your cycle time by causing the system to run for  
a shorter length of time. With the STAGE TIMER (Option 10) set to 0, stages 2 and 3  
will be controlled by the SPAN setting only. If the stage timer is set to 30, the system  
will turn on the next stage based on the SPAN setting or 30 minutes, which ever  
comes first.  
Span settings remain the same for Heating and Cooling.

CHANGE BATTERIES  
The CHANGE BATTERIES warning indicates two stages of battery power shortage.  
When the batteries are weak, the CHANGE BATTERIES warning flashes until three  
new AA alkaline batteries are installed. If the batteries become too weak for normal  
operation, the thermostat enters the second battery power shortage mode.  
When no battery power is left, the BATTERIES USED UP warning flashes on the  
display and the system turns off. The system remains off until new batteries are  
installed. The thermostat resumes normal operation after new batteries are installed.
