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
