ꢁOTICE! Do not disconnect the wires

from the existing thermostat before

reading these instructions. The wires

must be labeled prior to removal to

ensure proper reconnection.

UꢁIꢁSTAꢂꢂIꢁG THE EꢃISTIꢁG UꢁIT

. Turn the system power OFF from the existing

thermostat. Turn the power to the HVAC

system OFF at the main power panel or at the

furnace.

2. ꢀemove 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.)

. ꢂocate, 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.)

If your existing

thermostat is marked...

label the wire

with this sticker:

. Using the provided stickers, label each wire

according to the chart.

standards, so wire color should be ignored.

efer to the existing terminal designation for

ꢀ

proper identiﬁcation.

If a wire marked C is present, C may be a

Common wire and should not be used. If you have

a wire marked C, do not connect it to any terminal.

This wire is used only for non-battery powered

thermostats.

. 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.

2. Position the new wall plate on the wall and pull

the labeled wires through the opening.

. If the existing holes do not match those on the

Hunter wall plate, or if there are no existing

holes, level the wall plate and mark the wall for

two holes.

. ꢀemove the wall plate and drill two 3/16” holes

where marked.

. Tap the plastic anchors into the holes until they

are ﬂush with the wall.

. ꢀeposition the wall plate on the wall, pulling the

wires through the opening. Insert the mounting

screws through the mounting holes and into the

anchors. Verify that the thermostat is visually

level and securely tighten both screws.

screws.

ꢁ

ote: A jumper wire has been provided, connecting the

C and ꢀH terminals for systems that do not provide both

ꢀ

an ꢀH and ꢀC wire. If you have both an ꢀH and ꢀC wire,

remove this jumper. If you do not have both an ꢀH and ꢀC

wire, leave the jumper in place.

. Match and connect the wires from the wall

to the terminals as shown. Wires should be

inserted behind the black terminal shields.

Tighten each screw after the connection has

been made.

(The ends of any extra wires should be wrapped in

electrical tape and carefully pushed back into the wall.)

. Push any excess wire length back into the wall

to prevent interference.

. ꢂocate the HE/HG s w it c H on the back of the

thermostat. Set the switch to HG for a gas

furnace or oil burner. Set the switch to HE for

electric furnaces.

(The switch has no effect when the system is set to

cooling mode.)

5. Insert two fresh AA alkaline batteries.

6. Align the thermostat with the the wall plate,

. The Ba t t E r y in d ic a t o r displays two stages of

battery conditions. The ﬁrst warning is the

wE a k Ba t t E r y wa r n in G , indicated by the Ba t t E r y

in d ic a t o r ﬂashing once approximately every

second. When this warning appears, install

two fresh AA alkaline batteries at your earliest

convenience.

. The second warning is the sH u t -d o w n in d ic a t o r ,

indicated by the Ba t t E r y in d ic a t o r ﬂashing

approximately twice every second. When this

warning appears, the thermostat is shut down

and will turn your system OFF. Your system

will remain shut-off until you install two fresh

AA alkaline batteries.

Your thermostat is preset to cycle your system

off and on at 1 F above and below the Set

Temperature. For maximum system efﬁciency and

a sustained comfortable temperature your system

should cycle 3 - 5 times per hour. If your system is

cycling either too often or not often enough, then

use a small Phillips-head screwdriver to turn the

sp a n ad j u s t left or right to change the cycle time.

1. ꢀemove the top cover from the thermostat.

. To make your system run ꢂOꢁGEꢀ, turn the

sp a n ad j u s t clockwise.

. To make your system run SHOꢀTEꢀ, turn the

sp a n ad j u s t counter clockwise.

4. ꢀeattach the top cover to the thermostat.

ꢁ

ote: The Span range is 0.6 F - 3 F. The Span setting remains

the same in both the Heat and Cool modes and can be

changed regardless of what position the System Switch is in.

1. My heating or cooling will not turn on or off.

a. Check the HE/HG switch to ensure it is set to the correct

position.

b. Wait. There may be as much as a 4-minute delay before

the system turns on or off to protect the compressor.

c. Check the circuit breakers and switches to ensure there is

enough power to the system.

d. ꢀeplace the batteries with fresh AA alkaline batteries.

e. If applicable, make sure the furnace blower door is closed

properly.

f. If your system has 4 wires, ensure the jumper wire is

installed between the ꢀC and ꢀH terminals.
