Thermostat Front Panel Buttons — The thermo-  
stat has buttons under the front cover which are used for vari-  
ous functions such as raising or lowering the desired set point  
and changing the current mode. See Fig. 2.  
SET BUTTON — This button enters the thermostat program-  
ming schedule and allows the user to adjust the clock and  
change the calendar.  
SCHEDULE BUTTON — This button allows the user to  
choose to follow a schedule, hold the current set points, or go  
into holiday mode.  
OCCUPIED BUTTON — This button temporarily changes  
the thermostat from Unoccupied to Occupied settings.  
MODE BUTTON — This button selects whether the thermo-  
stat is set for heating, cooling, emergency heat, auto (heat and  
cool as needed), or off modes.  
DONE BUTTON — This button saves the settings when  
completing a setup or programming step.  
GENERAL  
The Edge Pro thermostat by Carrier is a wall-mounted, low-  
voltage control which combines temperature and humidity  
control in either a single or two-piece unit. The Edge Pro ther-  
mostat 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 in-  
ternal 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 hu-  
midification and dehumidification.

offer three humidity options: normal, auto, and off.  
CONFIGURATION  
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 con-  
stant, regardless of the outdoor temperature. The user can man-  
ually adjust the humidity level according to their own prefer-  
ences.  
The second option, “auto humidify,” uses an outdoor tem-  
perature sensor (if installed) to automatically adjust the indoor  
humidity level according to the outside temperature.

Service Reminders — The thermostat tells the user  
when it is time to change the UV light, change the filter, or per-  
form 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.  
5. Press the done button.  
6. Close the thermostat door.  
To temporarily unlock the keypad, open the thermostat door.  
Press and hold the up and down buttons simultaneously for  
about 5 seconds. The padlock icon will disappear. This means  
the keypad is unlocked and can be used. The keypad will revert  
back to the locked state after no buttons are pushed for 2 min-  
utes. Close the door.  
Outdoor Temperature Display — The thermostat  
automatically displays the outdoor temperature when the ther-  
mostat door is closed.  
PROGRAMMABLE / NONPROGRAMMABLE SET-  
TING — It is possible to convert the thermostat operation  
from programmable to nonprogrammable. This eliminates the  
advanced features. When switching to the nonprogrammable  
format, the programming, hold, holiday and Smart Recovery  
features are lost. Switching to nonprogrammable operation also  
means that some of the thermostat’s energy saving features are  
lost. The time of day and day of the week will still show on the  
display and the user will still be able to increase or decrease the  
temperature settings manually.  
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 transi-  
tions 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 set-  
ting is lower than the period that precedes it, then the thermo-  
stat will start cooling down the space before the beginning of  
the scheduled unocc period. The thermostat does this at an en-  
ergy efficient rate. This not only helps make the space as com-  
fortable as possible, it also makes thermostat usage more cost  
effective.
