Detailed Explanation of User Options: Service Monitors (Filter, UV and Humidifier Pad)
User Options 1, 2 and 3
There are three user selectable service monitors that will display reminders for a required air filter, UV bulb or humidifier pad replacement. The SERVICE segment flashes in the display along with FILTER, UV or HUMID. When the service interval has been reached, and required cleaning or replacement has been performed, touch the RETURN TouchPad to reset the timer. Select OFF or a set number of days before the reminder will appear
Extended Hold Period User Option 4
The Extended Hold Period lets you select the period your thermostat will hold the temperature when the HOLD mode is activated (See Setting the Temperature, page 23). When LONG is selected the thermostat will hold your temperature indefinitely. When 24HR is selected, the thermostat will hold your temperature for 24 hours and then return to the current program at that time. Not available in non-programmable mode.
Temporary Override Adjustment Limit User Option 5
The Temporary Override Adjustment Limit will limit how much the thermostat can be adjusted from the current set point when the thermostat is used in the programmable mode. This setting will not allow the user to override the temperature past the selected limit amount of 1, 2 or 3 degrees from the current set point. When the user reaches the adjustment limit the screen will flash ADJ. A setting of 0 disables the adjustment limit. The Temporary Override Adjustment Limit can also be used in the non-programmable mode if the keypad lockout security level is set to level 1 (See Installer Manual).
Program Override Time Limit User Option 6
The Program Override Time Limit allows you to set a maximum time limit (in hours) that the thermostat will return to the program after a temporary temperature adjustment has been made (See Setting the Temperature, page 23). You may select 1, 2, 3 or 4 hours. Not available in non-programmable mode.
Thermostat Lock Code User Option 7
The Thermostat Lock Code sets a 3-digit code that you may use at any time to lock or unlock the thermostat. Setting the code in the user options mode does not activate the lock feature (See Locking/Unlocking Thermostat, page 29). You may choose a 3-digit code with each digit being 0-9.

Setting the SYSTEM Control Mode
The System Control has 5 modes of operation – AUTO, COOL, OFF, HEAT and EMER. The mode can be selected by touching the SYSTEM TouchPad to scroll through the different modes
Setting the FAN Control Mode
The Fan Control has 4 modes of operation – AUTO, ON, CIRC and PROG. The mode can be selected by touching the FAN TouchPad to scroll through the different modes.
Temporary Adjustment – Press the SpeedBar® up or down to adjust the current set temperature. If your thermostat is running in 5-2 or 7 day programmable mode, the set temperature will change back to your original programmed settings when your next scheduled change in temperature occurs.
Extended Adjustment – Touch the HOLD TouchPad so that HOLD appears in the display screen. Press the SpeedBar up or down to adjust the current set temperature (See Extended Hold Period, page 10).
Status indicators appear in the display to let you know what part of your system is running.
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”.
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
Compressor Protection
Locking and Unlocking the Thermostat
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).
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
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.
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. Never use any abrasive cleansers to clean your thermostat
Changing the Batteries
This thermostat requires two (2) properly installed “AA” alkaline batteries to maintain the thermostat clock and to provide power for the thermostat if 24 volt AC power is not connected. (See Installer Manual). If batteries become low, a battery indicator will appear in the display. You should change your batteries immediately when you see the low battery signal by following these instructions.
