designed to keep the interior space above freezing by energizing the
electric heater anytime the indoor room temperature falls to 40° F (4° C) .

indoor temperature fall to 40° F (4° C) the unit will run the heater and high

Temperature Offset – In some cases the built in thermostat on the unit
may not display the temperature as it is felt in the room. This can be caused
by many things including the size of the unit, the heat load on the room or
other factors. Friedrich allows you to select the appropriate temperature
offset to make the temperature readout as accurate as possible for your
application. In many cases the factory 0° F (-18° C) offset will provide
an accurate temperature readout. To change the offset follow these
instructions. When TO is displayed press the
(UP) or (DOWN) to toggle between 0° F (-18° C) and 8° F (-13° C) .
In most instances an offset from 0° F (-18° C) to 2° F (-17° C) is all that is
necessary. To accept the change, press the
screen. Press the (UP) to go to the next menu ATSF.
You may cycle through the menus using the

Automatic Temperature Sampling Feature - The automatic temperature
sampling feature maintains a balanced temperature throughout the room
by circulating the air for 30 seconds once every 9 minutes that the unit is
not running when it is set to cooling or heating mode. By circulating the air
the unit can detect hot or cold areas in the room and operate the unit to
cool or warm the room as necessary. This function is only available when

only available on Kuhl+ units)
