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.
