Resetting the Thermostat

This thermostat provides you with a reset button that will erase all of your user settings and programming. The reset feature does not affect the Installer Settings. To reset the thermostat, use a small object such as a tooth pick or paperclip and gently press the button located inside the small hole on the front of the thermostat housing labeled “reset”.

Additional Operation Features

Auto Changeover Mode
Auto Changeover mode is a feature enabled/disabled in the Installer Settings (see Installer Manual). If enabled, it is selected by touching the SYSTEM TouchPad until AUTO HEAT or AUTO COOL appears below the TouchPad. When Auto Changeover mode is enabled and selected, the system automatically switches between heating and cooling when the room temperature meets the programmed heating or cooling set points. To operate properly, the thermostat requires a “dead band” setting to eliminate program conflicts. The dead band is set in the Installer Settings (See Installer Manual). The default setting is 3° F. Therefore, you will not be able to set your heat or cool temperature within 3° F of each other. If a setting is made in either heating or cooling which violates the dead band, the opposite mode will adjust up or down automatically to maintain the programmed dead band spacing.

Adaptive Recovery Mode (ARM™)
Adaptive Recovery Mode is a feature enabled/disabled in the Installer Settings (See Installer Manual). If enabled, the feature is automatically present while in programmable mode. Adaptive Recovery Mode tries to reach your desired heating or cooling temperature at the time you have set in your current program schedule, after a setback period. For example, if you set your heat down to 62° at night and have a set point of 70° scheduled for 7:00 AM, the thermostat may turn on your heating system early in order achieve a temperature of 70° by 7:00 AM. This feature does not operate when the thermostat is in HOLD mode, if the program is temporarily overridden or if emergency heat is selected on a multistage heat pump system.

Circulating Fan Mode
Circulating Fan Mode is selected by touching the FAN TouchPad until CIRC appears in the display. Fan operates as required by heating and cooling system (just like AUTO mode). When heating or cooling is not active, fan will run as needed to ensure a 35% minimum run time

Programmable Fan Mode

• Programmable Fan Mode is selected by touching FAN until PROG appears below the FAN TouchPad. It is only available in programmable mode.
• Programmable Fan Mode allows the user to run the fan continuously during a selected program event. To use this feature, select fan ON while setting program events. (See “Setting Your Program Schedule”, page 12).
• The Programmable Fan Mode is not available if the Circulating
• Fan Lock was enabled in the Installer Settings or if in non-programmable mode (See Installer Manual ).

Compressor Protection

• Compressor protection is enabled/disabled in the Installer Settings (See Installer Manual). If enabled, this feature is automatically present in cooling and/or heating modes.
• This thermostat includes an automatic compressor protection delay to avoid potential damage to your system from short cycling. This feature activates a short delay after turning off the system compressor.
• Additionally, for multi-stage heat pump systems, this thermostat provides cold weather compressor protection by locking out the compressor stage(s) of heating for a period of time after a power outage greater than 60 minutes.
• This cold weather compressor protection can be manually overridden at any time by changing the system mode to OFF momentarily, then back to HEAT.

Locking and Unlocking the Thermostat

• • Your 3-digit Lock Code is set in the “User Options” portion of this manual (See “Setting User Options”, page 8 and 11).
  • Once the code is set, the thermostat can be locked or unlocked at any time by entering that code.
  • To lock or unlock the thermostat, touch and hold the CLEAN and CONFIG TouchPads together for 5 seconds (Figure 1).
  • The screen will change, displaying 000 and LOCK will be flashing (Figure 2). Press the SpeedBar® up or down to enter the first digit of your lock code and then touch NEXT to advance to the next digit. Repeat this process to enter the second and third digit of your lock code.
  • After entering the third digit, touch RETURN.
    

If you entered a valid code the thermostat will be locked or unlocked (depending on its previous state). When locked, the word LOCKED appears in the display (Figure 3). If an invalid code is entered the word NO will briefly appear, indicating that an incorrect code was entered (Figure 4).

AC Power Monitor

The AC Power Monitor feature is enabled in the Installer Settings (See Installer Manual). If enabled, this feature will automatically be present. If your thermostat was hardwired (power provided from the system with batteries as a backup) then the AC Power Monitor feature will indicate when a loss of power to the thermostat has occurred by displaying NO POWR.

Indoor Remote Sensing Indoor remote sensing is achieved by installing a remote indoor sensor and is configured in the Installer Settings (See Installer Manual). If an indoor remote sensor was installed and properly configured in the Installer Settings, the thermostat will sense temperature at a remote location or at a combination of a remote location and the thermostat location.

Outdoor Remote Sensing

• Outdoor remote sensing is enabled by installing a remote outdoor sensor. No additional configuration is required.
• If an outdoor remote sensor was installed you will see the OUTDOOR TouchPad on the right side of the main display screen (Figure 1). To view the outdoor temperature, touch OUTDOOR.
• The current outdoor temperature will be displayed for 5 seconds (Figure 2).
• The outdoor sensor can also be configured in the Installer Settings (See Installer Manual) to automatically control advanced thermostat functions.

Humidification and Dehumidification

This thermostat can be used to control the level of humidification and dehumidification. Humidification can be controlled manually from the thermostat or automatically when an outdoor remote sensor is installed and configured in the Installer Settings (See Installer Manual). To view the current humidity level at the thermostat, touch the HUMIDITY TouchPad (Figure 1). If humidification and dehumidification are not enabled, you will only see the current humidity level. If humidification is enabled you will see the current humidity level along with the humidification set point (Figure 2). Press the SpeedBar®up or down to adjust the humidification set point. If dehumidification control is enabled, the air conditioning system can be used to reduce humidity during the cooling season. If the room humidity level is above the dehumidification set point, the air conditioning system may run until the room temperature is several degrees lower than the cooling set point, or until the room humidity level reaches the dehumidification set point (which ever comes first).

If humidification and dehumidification are both enabled you will first see the current humidity level along with the humidification set point. Press the SpeedBar® up or down to adjust the humidification set point. Touch HUMIDITY again to display the dehumidification set point. Press the SpeedBar up or down to adjust the dehumidification set point (Figure 3). Touch RETURN. NOTE: If Automatic Humidity Control was enabled in the Installer Options, the humidification set point may be automatically adjusted to compensate for changes in outdoor temperature. When there is a call for humidification a small water droplet symbol will appear in the screen (Figure 4). When there is a call for dehumidification, the word DEHUMID will appear.

Thermostat Maintenance

Screen Cleaning
To access the screen cleaning mode hold the CLEAN TouchPad for 3 seconds (Figure 1). The screen will display a countdown timer for 30 seconds (Figure 2). During this time the screen will be locked and you may proceed with cleaning the screen. After 30 seconds the display will return to normal. Never spray any liquid directly on the thermostat. Spray your cleaning liquid on a soft cloth and then proceed to clean the screen with the damp cloth. Only use water or household glass cleaner.
