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 (UP) or (DOWN) to toggle between ON
User presses or to select between Freeze Protection On
& Freeze Protection Off. Press the key to accept the
change and exit the selection process.

and OFF. To accept the change, press the key to return to the FRZ
screen. Press the (UP) to go to the next menu TO.
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 ATSF.
You may cycle through the menus using the (UP) or (DOWN) keys
User presses or to increment/decrement the temperature
offset (TO) for the room temperature sensor. (Maximum offset
= +/- 8 degrees F). Press the key to accept the change
