IMPORTANT: Read entire instructions before programming the thermostat. NOTE: The lockout code sequence is Mode, Copy Previous Day, Set Time, and Hold. HOLD BUTTON OPERATION Pressing the Hold button disables the time and temperature schedule and holds the current desired temperature set point. When a Hold is active, the HOLD annunciator is displayed on the thermostat screen. To release the Hold, press the Hold button a second time. The Hold will remain active for a duration of 4 hours, or until a new time schedule starts. FAN BUTTON OPERATION The Fan button selects fan operation. When the fan is set to ON, the fan will run continuously for improved air circulation. When the fan is set to AUTO, the fan will run during heating and cooling operation only. During setback mode (UN1, UN2), the fan will always be in AUTO mode. MODE BUTTON OPERATION The Mode button selects the operating mode of the thermostat. If OFF is selected, the thermostat will not enter heating or cooling mode. If HEAT is selected, the thermostat will only enter heating mode (if the room temperature is below the heating set point). If COOL is selected, the thermostat will only enter cooling mode (if the room temperature is above the cooling set point). If AUTO is selected, the thermostat will enter heating or cooling mode based on the room temperature and the heating and cooling set points. Heat pumps also have an EHEAT selection. If EHEAT is selected, the heat pump will use the second stage of heating to provide heating if necessary. The annunciator for each selection will be displayed on the thermostat when selected. AUTO-CHANGEOVER When the thermostat mode is set to AUTO, the thermostat will provide automatic changeover from heating to cooling mode and cooling to heating mode when required. The thermostat will automatically switch to maintain the desired temperature setting. The thermostat does not need to be manually changed from heating to cooling or cooling to heating operation. NOTE: It is recommended that auto-changeover mode not be used if the outdoor temperature is consistently lower than 50 F or greater than 80 F. In these cases, select heating or cooling mode only. SMART RECOVERY (HEATING MODE) The smart recovery function is designed to save energy by gradually adjusting temperatures to meet scheduled set points. The thermostat has 2 schedule modes, normal occupied mode and setback mode (a time when the space is unoccupied). The Smart Recovery function begins 1 to 1.5 hours before the scheduled occupied mode and gradually adjusts room temperature so the temperature is at the occupied mode set point when the occupied time period begins. This is more efficient than making the system run at full capacity until the desired temperature is met. NOTE: Smart recovery does not apply to cooling operation.

GENERAL

Carriers 7-day, commercial, programmable thermostats are wall-mounted, low-voltage thermostats which maintain room temperature by controlling the operation of an HVAC (heating, cooling and ventilation) system. Separate heating and cooling set points and auto-changeover capability allow occupied and unoccupied programming schedules for energy savings. All thermostats allow up to 4 time/temperature settings to be programmed per 24-hr period. Each thermostat stores programs for 7 independent days. Batteries are not required. During power interruption the internal memory stores programs for an unlimited time.

OPERATION

Thermostat Display The thermostat display is located in the top center of the thermostat. See Fig. 1. The following information can be displayed on the screen: mode (OFF, EHEAT, COOL, AUTO, or HEAT) fan setting (ON or AUTO) hold status room temperature desired temperature clean lter status time of day day of the week schedule period (OC1, UN1, OC2, or UN2) outdoor temperature (optional)

Thermostat Programming Buttons The thermostat has programming buttons which are used to change the set points of the thermostat, set the modes, and program schedules. The programming buttons are accessible from underneath the thermostat cover. To access the programming buttons, pull on the hinged thermostat cover. See Fig. 2. The programming buttons are: Copy Previous Day, Program, Mode, Change Day, End Program, Fan, Set Time, Reset Filter, and Hold. The Up and Down buttons are used to change the current, desired temperature set point and to scroll through programming set points. The Up and Down buttons are accessible from the outside of the thermostat. The daily schedule can be overriden in 2 ways: pressing the Hold button, or pressing the Up and Down buttons to change the temperature set point. PROGRAMMING BUTTON LOCKOUT The thermostat has a lockout feature which will not acknowledge programming buttons until the lockout code is entered. After the lockout code has been entered, the keypad will remain unlocked until the user has stopped pressing buttons for 2 minutes. The lockout feature is congured by the installer.

Set Current Day The Change Day button will change the day shown on the thermostat display to the next day. If a schedule has been entered, the thermostat will follow the schedule of the new selected day. Set Current Time The Set Time button allows the
user to change the time displayed on the thermostat. Press the Set Time button. The display will show the SET TIME annunciator. Press the Up and Down buttons until the correct time is shown. Hold down the buttons to quickly move through the time display. The AM and PM annunciators will automatically change. To ensure the schedules are properly followed, make sure that AM or PM is correct for the time chosen. When the correct time is shown, press the Set Time button again to exit the Set Time mode.
Reset Filter The Reset Filter button is used to clear
the Clean Filter icon on the display screen. The Clean Filter icon reminds the user when it is time to change or clean the lter of the unit.
Programming Thermostat Schedules Before programming the thermostat, plan the thermostat daily schedule. The schedule is divided into 7 days (Monday through Sunday). Each day has 4 time periods (OC1, UN1, OC2, UN2). Each time period has a start time, heating set point, and cooling set point. Fill in the table below as an aid to programming the daily schedules. PROGRAMMING MODE To program the daily schedules, perform the following procedure: 1. Enter programming mode by pressing the Program button. The PROGRAMMING annunciator will appear on the thermostat display. The rst day of the schedule (MON) will be displayed and the rst programming time period (OC1) of that day will be displayed. The SET TIME annunciator is also displayed. NOTE: If a programming button is not pushed for 60 seconds, the thermostat will exit programming mode and any changes made will be saved. 2. Press the Up and Down buttons to set the start time for the schedule day and period shown (MON, OC1). 3. Press the Program button once the correct time is shown. The SET TIME annunciator will turn off and the SET DESIRED TEMP annunciator will be displayed.

4. The heating and cooling set points can now be programmed. The HEAT and COOL annunciators are displayed for the heating and cooling set points respectively. The mode button is used to toggle between the heating and cooling set points. Use the Up and Down buttons to raise and lower the temperature set points. NOTE: There must be at least 3 degrees difference between the cooling and heating set points. The thermostat will automatically change any set points closer than 3 degrees. 5. Press the Program button to advance to the next time period (UN1). 6. Perform Steps 2 through 5 until the times and temperature set points have been entered for the entire day. Press the Change Day button to move to the schedule for the next day. 7. Repeat Steps 2 through 6 to program the remaining schedule days. The Copy Previous Day button can be used to copy the previous days schedule if the schedules are the same. 8. After all the times and set points for each day have been entered, press the End Program button to nish entering the schedule. NOTE: The thermostat will continue to follow the schedule until a new one is entered. The schedule may need to be updated for different seasons or prolonged changes in temperature. OVERRIDING THE SCHEDULE The schedule can be overridden in two ways, the Hold button can be pressed to lock in the current temperature setting, or the Up or Down buttons can be pressed to change the desired temperature. The thermostat will use the held or new set point until the next scheduled time period starts (with a maximum Hold time of 4 hours). CHECK OUTDOOR TEMPERATURE To check the outdoor temperature, press the Up and Down buttons simultaneously. The outdoor temperature will be displayed. If 2 dashes (--) are displayed, the thermostat does not have an outdoor thermostat or the thermostat is not working properly. Contact the servicing contractor if a problem occurs.
