Freeze Protection – The Kühl+ models have a special feature that is
designed to keep the interior space above freezing by energizing the
electric heater anytime the indoor room temperature falls to 40° F (4° C) .
With the freeze protection feature turned on, when the unit senses the
indoor temperature fall to 40° F (4° C) the unit will run the heater and high
fan until the space reaches 46° F (8° C) When FRZ is displayed press
the
key then press

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
key then press
(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
key to return to the TO
screen. Press the
(UP) to go to the next menu TIME.

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 and set to cooling or heating mode. By circulating the air the
unit can detect hot or cold area in the room and operate the unit to cool or
warm the room as necessary. This function is only available when the fan
mode is set to ‘AUTO’ and in COOL or HEAT mode. (Heating function only
available on Kuhl+ units)
