Setting the Temperature
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 toothpick or paperclip and RESET gently press the button located inside the small hole on the front of the thermostat housing labeled “RESET”.
NOTE: You cannot reset the thermostat if it is locked.
Auto Changeover Mode
Auto Changeover mode is a feature enabled/disabled in the Installer Settings (see Installer Manual). If enabled, it is selected by pressing the SYSTEM button until AUTO HEAT or AUTO COOL appears in the display.
SYSTEM
When Auto Changeover mode is enabled and selected, the system automatically
AUTO switches between heating and cooling when the room temperature meets the
HEAT 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 F 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 a have a set point of 70° scheduled for 7:00 AM, the thermostat may turn on your heating system early in order to 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.
Programmable Fan Mode
Programmable Fan Mode is selected by pressing FAN until PROG appears in the display. It is only available in programmable mode.
FAN 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 10).
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 stages) 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”, pages 6 and 9). 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, press and hold the DAY/TIME and HOLD buttons together for 5 seconds. The screen will change, displaying 000 and LOCK will be flashing. Press the / or V buttons to enter the first digit of your lock code and then press NEXT* to advance to the next digit. Repeat this process to enter the second and third digits of your lock code. After entering the third digit, press RETURN.
*BACK and NEXT are secondary functions of the PROG and HOLD buttons.
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 1). If an invalid code is entered the word NO will briefly appear, indicating that an incorrect code was entered (Figure 2).
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 NOAC.
Indoor Remote Sensing
Indoor remote sensing is achieved by installing a CC®6390 remote indoor sensor and is configured in the Installer Settings (See Installer Manual). If a CTC 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 CTC 6490 remote outdoor sensor. No additional configuration is required
If a CTC outdoor remote sensor was installed you may press the PROG and HOLD buttons at the same time to view the outdoor temperature.
