NOTICE! 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.

UNINSTALLING THE EXISTING UNIT

1. 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. 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. 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, so wire color should be ignored. Refer to the existing terminal designation for proper identiﬁcation.

*If wires marked Y & C are both 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.

5. 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.

INSTALLING THE WALL PLATE

2. Position the new thermostat on the wall and pull the labeled wires through the opening.

3. If the existing holes do not match those on the Hunter wall plate, or if there are no existing holes, level the thermostat and mark the wall for two holes.

4. Remove the thermostat and drill two 3/16” holes where marked.

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

6. Reposition the thermostat 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.

CONNECTING THE WIRES

1. Loosen, but do not remove, the terminal screws.

Note: A jumper wire has been provided, connecting the RC and RH terminals for systems that do not provide both an RH and RC wire. If you have both an RH and RC wire, remove this jumper. If you do not have both an RH and RC wire, leave the jumper in place.

2. 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.)

3. Push any excess wire length back into the wall to prevent interference.

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.)

2. Locate the HP/STD switch on the wall plate. Set the switch to HP for Single-stage heat pump systems. Set the switch to STD for conventional systems.

INDICATORS AND ADJUSTMENTS, CONT.

Your thermostat is preset to cycle your system off and on at 1oF 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 and the Span Adjust to change the cycle time.

1. Remove the top cover from the thermostat.

2. To make your system run LONGER, turn the

Span

Adjust clockwise.

3. To make your system run SHORTER, turn the Span

Adjust counter clockwise.

4. Reattach the top cover to the thermostat.

Note: The Span range is 0.6oF - 3oF. remains the same in both the Heat and Cool modes and can be changed regardless of what position the System Switch is in.

1 a. Check the HE/HG switch to ensure it is set to the correct position. 1 b. Wait. There may be as much as a 4-minute delay before the system

turns on or off to protect the compressor.

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

power to the system. 1 d. Replace the batteries with fresh AA alkaline batteries. 1 e. If applicable, make sure the furnace blower door is closed properly. 1 f. If your system has 4 wires, ensure the jumper wire is installed

between the RC and RH terminals.
