CAUTION

The two Alkaline “AA” batteries must be replaced at least once every 12 months to ensure proper operation. The “Low Battery” icon will appear on the thermostat display when it is time to replace the batteries. If the thermostat is connected to 24v power, the batteries should still be installed, but are not required. When “Low Battery” is displayed the batteries must be replaced immediately. The manufacturer cannot be liable for improper operation of the thermostat if the batteries are not immediately replaced. Annual battery replacement is especially critical in locations subject to freezing temperatures. The thermostat will be unable to turn on the heating system if the batteries are exhausted.

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause undesired operation.

Location of Controls

Display

1. Day of the week. When programming, MTuWThF represent the five weekdays and SaSu represent the two weekend days.
2. Heat and Cool indicators. In normal operation, Heat or Cool appears, depending on the Mode Switch position. When heat or cool is energized, the Heat or Cool indicator will flash.
3. Clock Display.
4. Time period indicators. These indicate the part of the program that is currently active, if the Program Switch is positioned to RUN.
5. Desired set temperature.
6. Current room temperature.
7. Indicates that 2nd stage of heat is energized.
8. Indicates when the filter should be serviced. Appears after 0 – 1950 hours of blower operation (adjustable).
9. Indicates batteries need replacement.

Normal Operation

Manual Operation (Program Switch OFF)

1. Select Cool or Heat with the Mode Switch.
2. Normally leave the fan switched to Auto.
   In Fan Auto, the fan will turn on only with a heat or cool demand. When Fan On is selected, the fan will run continuously.
3. Adjust the desired set temperature with the COOLER and WARMER buttons.

Programmed Operation

1. Select Cool or Heat with the Mode Switch. Select RUN with the Program Switch.
2. Normally leave the fan switched to Auto.
3. In Fan Auto, the fan will turn on only with a heat or cool demand. When Fan On is selected, the fan will run continuously.
4. The desired set temperature may be temporarily overridden. The thermostat will revert to the programmed settings in the following time period.

Aux Heat

• Emergency – Disables all compressor functions* and energizes only Aux Heat to satisfy the heat demand.
• Normal – Aux Heat is allowed to run, if necessary, along with the heat pump to satisfy the heat demand.
• Lockout – Aux Heat will never turn on regardless of the heat demand.

When the Aux Heat switch is in the Emergency position the compressor will also be locked out during cooling operation.

Clock Set

Setting the time & day are the first two steps after sliding the Program Switch to SET.

Time Period Programming

Overview

• Slide the Program Switch to the SET position.
• The blinking icon(s) on the display may be changed by pressing the COOLER or WARMER buttons.
• After the blinking icon is changed to the desired selection, press the NEXT button.
• Each item in the time period programming screens will flash and can be modified with the COOLER & WARMER buttons. Continue the steps above until programming is complete. Slide the Program Switch to RUN and the thermostat will run the time period programming.
• If the Program Switch is in the OFF position, the thermostat will not run the time period program. In this case, the thermostat will be a manual heat or cool only thermostat.

Weekday Programming

Time Period Programming
After you have completed setting the time period programming, you have two options:

1. Run the time period program by sliding the Program Switch to the RUN position.
   Or,
2. Do not run the time period program. The thermostat will operate as a manual heat or cool thermostat. Slide the Program Switch to OFF in this case.

Advanced Setup

This is normally done by the installer at initial installation.
Enter advanced setup by sliding the Program Switch to SET. When the clock is flashing, press the NEXT button for 5 seconds. Do not release the button until this screen appears.

About Advanced Features & Operation

• CYCLES PER HOUR – The Cycles Per Hour setting (page 18) monitors the number of times per hour your HVAC unit may energize. For example, at a setting of 6 cycles per hour the HVAC unit will only be allowed to energize once every 10 minutes. The Cycles Per Hour limit may be temporarily overridden by pressing the WARMER or COOLER button.
• TWO STAGE OPERATION – The 2nd stage of heat (auxiliary heat) is turned on when the room temperature is equal to or less than: the setpoint minus the 1st stage deadband (one degree, adjustable), minus the 2nd stage deadband (two  degrees, non-adjustable).
• FILT ER ICON – The FILTER  icon will appear after a set number of hours for fan run time (see above) has been achieved. This counter keeps track of the number of hours of fan run time whether the fan is energized in the heating or cooling modes, or in stand alone operation.

Factory Default

If, for any reason, you desire to return all the stored settings back to the factory default settings, follow the instructions below. Enter advanced setup by sliding the Program Switch to SET. When the clock is flashing, press the NEXT button for 5 seconds. Do not release the button until this screen appears.

WARNING: This will reset all Time Period and Advanced Programming to the default settings. Any information entered prior to this reset may be permanently lost.

Calibration

Under normal circumstances it will not be necessary to adjust the calibration of the temperature sensor. If calibration is required, please contact a trained HVAC technician to correctly perform the following procedure.
Enter advanced setup by sliding the Program Switch to SET. When the clock is flashing, press the NEXT button for 5 seconds. Do not release the button until this screen appears.

Battery Replacement

1. Battery Replacement
2. Remove the old batteries and replace with the new AA alkaline batteries (fig. 3).
3. Place the bottom hook of the battery cover into the slot and snap closed (fig. 4).

The batteries must be replaced immediately when the thermostat displays the low battery icon (fig.1). If the thermostat is connected  to 24v power, the batteries should still be installed. Installing the batteries when system powered (24VAC) will keep the clock running in the event of line power interruption.
