ꢂ

44002-01 r051807

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

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.)

. 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.)

. 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.)

ꢆ

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.

MOUNTING THE WALL PLATE

. Remove the wall plate from the Hunter thermostat by gently pulling the wall plate

from the back of the thermostat.

2. Position the new wall plate on the wall horizontally and pull the labeled wires

through the opening.

. 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.

. Remove the wall plate from the wall and drill two 3/16” holes where marked.

. Tap the plastic anchors into the holes until they are flush with the wall.

. Reposition the wall plate on the wall, pulling the wires through the wall plate

opening. Insert the mounting screws through the wall plate and into the anchors.

Verify that the wall plate is level. Securely tighten both screws.

CONNECTING THE WIRES

. Loosen, but do not remove the terminal screws.

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.

. 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.

. 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.

ATTACHING THE THERMOSTAT

. Insert three AA alkaline batteries into the back of the thermostat.

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.

The PERIODS PER DAY (Option 1) can be set to 0, 2 or 4. When set to 0, the

thermostat operates as a digital non-programmable thermostat.

The FILTER CHANGE INDICATOR (Option 2) runs in calendar days and can be set from

0-360 days in 15-day increments (the default is 90).

The REFRESH FAN ON (Option 3) function runs only the fan during heating or cooling

off cycles. This balances the indoor air and improves air quality by cycling the air

through the filter.
