Improper wiring or installation may damage thermostat. Recognize safety information. This is the safety alert symbol . When the safety alert symbol is present on equipment or in the instruction manual, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety alert symbol.
DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard that could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or property damage.

GENERAL

The Edge Pro thermostat by Carrier is a wall-mounted, lowvoltage control which combines temperature and humidity control in either a single or two-piece unit. The Edge Pro thermostat can be set for 7-day, 5/2-day, or 1-day programmable operation. Different heating and cooling set points and times are programmable for 2 or 4 periods per day. The thermostat can also be configured for non-programmable operation. When operating as a non-programmable thermostat, the user will still have both temperature and humidity control. The Edge Pro thermostat has no need for batteries to store user-configured settings in memory. During power loss its internal memory saves settings for unlimited time, and the clock continues to run for at least 24 hours. An extension of Carrier’s proven line of thermostats, the Edge Pro thermostat provides separate set points for heating and cooling in addition to humidification and dehumidification.

Setting or Changing Heating and Cooling Set

Points

The Edge® Pro thermostat is installed with preset heating and cooling temperature settings. The user can use these settings or program new settings. The user can also temporarily change the temperature from the programmed set points.
The thermostat will hold these changes for two hours or until the next programmed cycle begins. The words “temporary hold” will be displayed while this is in effect. To change the amount of time that the temperature is on hold, press the soft key under the hold hours or minutes indicators. Then press the UP or DOWN button to adjust the hold time. Close the door when done.
To change the temperature for the specified “temporary hold” period, perform the following. Open the front thermostat door. An arrow will be displayed next to the words “off,” “heat,” or “cool” in the upper right corner on the screen, depending on the mode the system is in. If it is the first time the thermostat is being used, the “heat” indicator will be displayed. The preprogrammed heating or cooling temperatures are displayed in a box at the bottom of the screen. Change the displayed temperature set point by pressing the UP or DOWN button until the desired setting is reached.
To change other temperature set points, press the MODE button. The arrow will move to the next mode and the screen will show the related temperature set point in a box. Then press the UP or DOWN button to change the displayed set point. When there are arrow indicators next to both of the heat and cool indicators, the heating and cooling set points are both displayed at the bottom of the screen. The user can change either one by pressing the soft key underneath the set point to be changed. Press the UP or DOWN button to adjust the temperature. Repeat the process for the other set points if necessary. Press the DONE button when finished.

Holding Temperature Set Points

The user can override the programmed temperature settings and hold the temperature at a specific setting without the temperature changing during the next programmed period. To override the temperatures, perform the following:

1. Open the door.
2. Press the SCHEDULE button. The arrow will move to the hold indicator.
3. The screen will display the set point temperature. To change the set point temperature, press the UP or DOWN button. The temperature will stay at the new setting until it is released from the hold.
4. To change the heating set point when the cooling set points are displayed (and vice versa), press the MODE button until the arrow moves to the desired mode. Press the UP or DOWN button to change the set point.
5. To return the temperature to the preset level for that time period, press the SCHEDULE button until the arrow moves to the “follow schedule” indicator.
6. Close the door.

Unoccupied Override — The OCCUPIED button is only active:

1. during the unoccupied periods
2. when Hold is active
3. when Holiday is active

The OCCUPIED button is inactive during occupied periods (OCC, OCC2, and OCC3). When the user presses the OCCUPIED button, the set points change to the occupied settings and the temporary hold timer is set for two hours. The user can adjust the temporary hold timer to any value in 15-minute increments from 15 minutes to the maximum number of hours specified by the installer in configuration option 38.
When the temporary hold timer counts down to zero, the set points will change to the program schedule settings for that time of day. If smart recovery conditions are satisfied, the set points will change from the occupied values to the program schedule values. If Hold is active, the temporary hold timer is not displayed. The fan will run according to the setting specified by the installer in configuration option 36. When Holiday is active and the OCCUPIED button is pressed, the temporary hold timer is set for two hours, the heat and cool set points change to the occupied settings, the humidity control will use the “normal” (not holiday) settings, and the fan will run according to the setting specified by the installer in configuration option 36. If the remote indoor temperature sensor with override (part no. 33ZCT55SPT) is used, it will function the same as the local OCCUPIED button except that the button press will be inactive if the thermostat is in hold. The remote OCCUPIED button is located on the left-hand side of the sensor. Press and hold the button for at least two but not longer than five seconds to request an occupied override.

Programming Schedules

Changing the Humidity Level

some thermostats offer three humidity options: normal, auto, and off. This function is only available on 33CS2PPRH thermostats.
The thermostat is set at the factory for “normal humidify,” which is a fixed humidity setting based on how much humidity the user wants in the space. This humidity level remains constant, regardless of the outdoor temperature. The user can manually adjust the humidity level according to their own preferences.
The second option, “auto humidify,” uses an outdoor temperature sensor (if installed) to automatically adjust the indoor humidity level according to the outside temperature. The third option is to turn off the humidify/dehumidify feature.
To change the fixed (constant) humidity setting for normal humidify, perform the following procedure:

1. Open the thermostat door.
2. The “humidify” icon will be displayed at the bottom of the screen when the operating mode is heat. The “dehumidify” icon will be displayed when the operating mode is cool.
3. Press the soft key under the humidify or dehumidify icons. The screen will display the current setting.
4. Press the UP or DOWN button to change the humidity setting. It is factory set at 26% for humidify and 60% for dehumidify. If there is too much condensation in the space, set the value to a lower number. If the air is too dry, set the value to a higher number. Humidity can be set to between 10% and 46%. The dehumidify range is from 46% to 98%.
5. Close the thermostat door.

To change the humidity setting for auto humidify, perform the following procedure:

1. Open the thermostat door.
2. The “humidify” icon will be displayed at the bottom of the screen. Press the soft key under the humidify icon.
   The screen will display the current setting.
3. Press the MODE button. An auto icon will appear at the top of the screen. The current humidity reading and the auto humidify set point will also be shown. The default auto humidify set point is 5.
4. Press the UP or DOWN button to change the auto humidify setting number (1 through 9). If there is too much condensation on the windows, select a number lower than.
5. If there seems to be a lot of static electricity, which often means the air is too dry, select a number higher than 5.
6. Close the thermostat door.
   To turn off the humidify or dehumidify feature open the thermostat door. Press the soft key under the humidify or dehumidify icons. Then press the MODE button until the screen displays OF. Close the thermostat door.

5. Press the DONE button.
6. Close the thermostat door.

Service Reminders — The thermostat tells the user when it is time to change the UV light, change the filter, or perform scheduled maintenance. Each reminder will be displayed on the upper left of the screen. For important safety reasons, do not change a UV light; ask your dealer to replace the UV light. To remove the reminder after the service has been performed, press and hold the DONE button for about 3 seconds.

Outdoor Temperature Display — The thermostat automatically displays the outdoor temperature when the thermostat door is closed if a valid sensor has been wired to the thermostat.
Auto Changeover — The thermostat displays one of five modes: heat, cool, Em heat (heat pump version only), heat cool (auto mode) and off. When the mode selection is auto mode, the system is allowed to switch from heating to cooling or from cooling to heating to maintain the temperature set points.
Smart Recovery — The Smart Recovery feature transitions the space from one temperature period (occ, occ2, occ3, unocc) to the next so that the space temperature matches the temperature set point at the start of each time period. This means, for example, that if the unocc period temperature setting is lower than the period that precedes it, then the thermostat will start cooling down the space before the beginning of the scheduled unocc period. The thermostat does this at an energy efficient rate. This not only helps make the space as comfortable as possible, it also makes thermostat usage more cost effective.
Power Outage — If the building loses electricity, the thermostat will not need to be reprogrammed. The settings are retained in memory.
