1.Fan Operation

A.Press fan button, starting fan operation. Fan icon turns on.

B.Press Fan button, stopping fan operation. Fan icon turns off.

2.Heating Operation

A.Press and Release MODE button until HEAT is dis- played.

B.Press up button until LCD readout reads 10 degrees above room temperature. Heating system should begin to operate within 5 minutes.

3.Cooling Operation

A.Press and Release MODE button until COOL is dis- played

B.Press down button until LCD readout reads 10 degrees below room temperature. Cooling system should begin to operate within 5 minutes.

6.Secure back plate to wall with 2 anchors and screws provid- ed making sure all wires extend through hole in back plate.

7.Connect wires to proper terminal of the connector block

8.Push any excess wire back into wall. Excess wire inside the thermostat plastic case can interfere with proper air ﬂow across the temperature sensor. Seal hole in wall to prevent air leaks. Leaks can affect operation.

9.Install thermostat on back plate.

10.Turn on power to the unit.

On initial power up, the LCD readout will display oP.

IV. THERMOSTAT OPERATION

1.TEMPERATURE DISPLAY

The thermostat will display room temperature until the UP or DOWN button is pressed. The word SET appears when these buttons are pressed and the current set point is displayed. If no buttons are pressed for 5 seconds, the display will change back to show room temperature.

2.TIMEGUARD TIMER

A 5-minute timeguard is built into the thermostat immediately upon power up, and any time the compressor turns off. The compres- sor will not turn on until the timeguard has expired. Pressing UP and FAN buttons simultaneously will override the timeguard for 1 cycle.

3.CYCLE TIMER

In normal heating and cooling operation the thermostat will not allow more than 4 equipment cycles per hour (or 1 cycle every 15 minutes). Both the Y and W outputs have a 15-minute timer that starts counting down when the output is turned on, (e.g., if Y output is turned on for 9 minutes and then satisﬁes, it cannot turn back on for another 6 minutes regardless of demand). However, pressing UP and FAN buttons simultaneously or changing the set point will override the timer for 1 cycle.

4.MINIMUM ON TIMER

HEAT	W	W
COOL	Y	Y
FAN	G	G
24 VAC HOT	R	R
24 VAC COMM	C	C
Reversing Valve	B	B

Connection to “B” terminal required on Heat Pump models

Once the equipment has turned on, it will remain on for a minimum of 3 minutes regardless of demand. However, the equipment can turn off in less than 3 minutes if a change in set point, or a change in mode occurs.

5.ERROR MESSAGES

E4 will be displayed if the thermostat has an internal memory failure. If E4 appears, replace the thermostat.

-- (two dashes) will be displayed if the temperature cannot properly read the room temperature. If - - appears, replace the thermostat.
