THERMIDISTAT
TM
CONTROL
Carrier’s Thermidistat Control can be
used to control any equipment
application except zoning. It possesses
all the features and benefits of Carrier’ s
non-programmable and programmable
thermostats plus:
Enhanced Comfort — Allows the
homeowner to accurately maintain the
desired temperature and humidity
settings in the home. By combining the
functions of a programmable
thermostat and a humidistat, the
Thermidistat Control provides
temperature control, humidity control,
and dehumidification.
Humidity Control — The
Thermidistat Control accurately controls
humidity level. It humidifies during
heating and dehumidifies during cooling.
Automatic Humidity Adjustment
— When used with the outdoor
temperature sensor, the Thermidistat
Control automatically adjusts the
humidity setting, reducing excess
condensation on the windows.
V acation mode — With a single touch
of a button, vacation mode adjusts all
comfort levels for optimum ef ficienc y
while the home is unoccupied — or
restores the settings to normal upon
return.
Smart Recovery — Provides
consistent heating and cooling right on
time as it gradually adjusts indoor
temperatures before a scheduled change.
Non-Programmable Option —
Offers the same popular humidity
control benefits to consumers who do
not need the added benefits of
programming. Nine functional buttons,
along with the UP and DOWN b uttons,
make it easy to enter the temperature
and humidity set points. The LCD is the
largest display on the market for a nonprogrammable thermostat.
