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.
