To Remove Existing Thermostat

1. Turn off power to the heating system by removing the fuse or switching off the appropriate circuit breaker.
2. Remove cover of old thermostat. This should expose the wires.
3. Label the existing wires with the enclosed wire labels before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following sections for instructions on how to install this thermostat.

Replacing Wiring Labels 
Replace the old labels with the enclosed new labels.

Old	New	Type
F, G	G	Fan control relay
H, W, 4	W	Heating control
M, 4, RH, RS, R	R	Transformer, hot side
N/A	S1, S2	Optional remote sensor

To Install Thermostat

Note: Mount thermostat about five feet above the floor. Do not mount the thermostat on an outside wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.

1. Turn off power to the heating system by removing the fuse or switching off the appropriate circuit breaker.
2. Move the Fan Auto/On switch into Auto position.
3. To remove cover, insert and twist a coin or screwdriver in the slots on the sides of the thermostat.
4. Put thermostat base against the wall where you plan to mount it (Be sure wires will feed through the wire opening in the base of the thermostat).
5. Mark the placement of the mounting holes.
6. Set thermostat base and cover away from working area.
7. Using a 3/16” drill bit, drill holes in the places you have marked for mounting.
8. Use a hammer to tap supplied anchors in mounting holes.
9. Align thermostat base with mounting holes and feed the control wires through wire opening.
10. Use supplied screws to mount thermostat base to wall.
11. Insert stripped, labeled wires in matching wire terminals. See “Wiring Diagrams” section of this manual.
    CAUTION! Be sure exposed portion of wires does not touch other wires.
12. Tighten screws on terminal block. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper terminal.
13. Set the GAS/ELEC jumper to Electric or Gas/Oil
14. Insert two fresh “AA” alkaline batteries into thermostat, oriented in the direction shown on the battery compartment.
15. Replace cover on thermostat by snapping it in place.
16. Turn on power to the system at the main service panel.

Installing and Changing Batteries 
If your LCD is blank or displaying LO BAT, the batteries are not installed or need to be changed. We suggest you change the batteries at least once a year, or whenever the LO BAT warning displays.
Note: After installing new batteries, you have to reset the room temperature setting and the differential setting.

1. Move the Off/Heat switch into the Off position.
2. Move the Fan Auto/On switch into Auto position.
3. Remove the cover, and install the two “AA” alkaline batteries. Proper battery installation is important! Make sure the positive ends of the batteries match the positive terminals in the battery compartment.
   If the display is on, the batteries are installed properly.

Remote Sensor Installation (Optional)

1. Remove cover from remote sensor housing.
2. Select an appropriate location for mounting the remote sensor.
3. Mount remote sensor unit using hardware provided.
4. Install two conductor shielded wires between remote sensor and thermostat. Shielded wire must be used. Do not run remote sensor wire in conduit with other wires.
   Wire 1 should run between the S1 terminal on the thermostat and the S1 terminal on the remote sensor
   Wire 2 should run between the S2 terminal on the thermostat and the S2 terminal on the remote sensor
   Connect the shielding of the wire to the S2 terminal on the thermostat
5. Disable the main sensor on the thermostat by cutting it from the circuit board.

Heating Only

Zone Valve/Damper Motor System

Setting the Setpoint Temperature

1. Place Off/Heat switch in the Heat position.
2. Press the down or up button a single time to see the current temperature setting.
3. Press the down or up button until the desired temperature setpoint displays.
4. The new temperature setpoint is automatically saved in memory. After 5 seconds, the display returns to showing the current room temperature.

Setting the Temperature Differential 
The default temperature differential is 1°. When your room temperature varies by 1°F, the thermostat turns on your system. If you notice your system turning on and off too frequently, increase the temperature differential.

1. Reset the thermostat by removing batteries for 10 seconds and then reinstall them.
2. For the first 10 seconds of operation, the temperature differential is displayed.
3.  Press the down or up button to select desired setting.

Starting the Thermostat

1. Move the Fan Auto/On switch into the Auto position.
2. Move the Off/Heat switch into the Heat position.

A Quick Test

Do not short jumper across terminals on the gas valve or at the system control to test installation.

• Action: Set the Off/Heat switch to Heat; press the up button until the set temperature is 5°F above the room temperature.
  Result: Heating system and fan should turn on; there may be a time delay depending on your system.
• Action: Press the down button until the set temperature is below the room temperature.
  Result: The heating system should turn off; there may be a fan delay.
• Action: Set the Fan Auto/On switch to On.
  Result: The blower fan should turn on.
• Action: Set the Fan Auto/On switch to Auto.
  Result: The blower fan should turn off.
  If the above test was successful, you have a proper installation.
  If the above test was unsuccessful, double-check that the wires are securely connected and are connected to the proper terminals. Consult the troubleshooting section below.

Troubleshooting

Symptom	Remedy
The system is not turning on	Check batteries; display is blank when batteries are not present or are dead.
LCD is blank, or displaying LO BAT	Replace batteries, or make sure the existing ones are properly installed.
Thermostat is not properly controlling the fan	Check that the GAS ELEC jumper position matches your system (gas or electric).
Thermostat turns on and off too frequently	Adjust temperature differential (see “Setting the Temperature Differential”).
