Operating The Controls - Whirlpool ATE0743SPP Technical Manual

TEMPERATURE CONTROL
The temperature control is a full range thermo-
stat that maintains room temperature at the
desired setting for both heating and cooling.
Turn the knob counterclockwise for a warmer
temperature, and clockwise for a cooler tem-
perature.
NOTE: Always rotate the temperature control
in small increments in the warmer or cooler
direction. Moving the control more than 1/4" at
a time may overcompensate, and result in an
extreme hot or cold condition.
MODE (SYSTEM) SWITCH
Low and High Cool
This setting operates the unit in the "cooling"
mode. Cooling will not begin if the room tem-
perature is below 60°F (15.5°C).
Low and High Heat
This setting operates the unit in the "heating"
mode.
Fan Only
This setting operates the fan continuously at
high fan speed to circulate air within the room.
No heating or cooling functions are active in
this mode.

TEMPERATURE LIMITING
THERMOSTAT
The temperature limiting thermostat allows the
temperature range of the thermostat to be
varied.
To adjust the temperature range:
1. Turn the thermostat (temperature) control
to the center position.
2. Pull the two control knobs off the control
shafts and remove them.
3. Remove the four screws from the control
panel and rotate the panel up.
4. Note the location of the two temperature
limiting screws and remove the screws
from their present location. NOTE: The
screws are factory installed for a tempera-
ture range of between 60 and 90°F (15.5
to 32.2°C).
5. To adjust the temperature range, reinstall
the two screws at the desired hole loca-
tions. NOTE: Each hole represents an
approximate change of 4°. To set a maxi-
mum temperature range of approximately
64 to 86°F (17.7 to 30.0°C), install the two
screws at the hole locations shown in the
round illustration below.
6. Lower the control panel and install the two
screws, then reinstall the two control knobs.
