Changing temperature controller settings – optional

Follett’s temperature controller is pre-programmed with a -25 C (-13 F)
set point and degrees C display. The -25 C (-13 F) set point delivers a
temperature range of -23 to -25 C (-9 to -13 F). Follett’s controller set point
can be changed to deliver up to a -15 C (+5 F) temperature for applications
where a lower temperature is not desired (i.e. ice cream). See page 6 to
change controller settings.

Rocker buttons to the right of the temperature display control all
programming functions.

The controller is pre-programmed with a -25 C (-13 F) set point
which provides a compressor cut-in at -23 C (-9 F) and cut-out at

-25 C (-13 F). The controller set point can be raised to -15 C (+5 F)

for nourishment applications where a lower temperature is not
desired (i.e. ice cream). Follow instructions for changing temperature
cut-out below.

All set points have a 2 C differential. The 2 C differential means that with a -25 C set point, for example, the
compressor will turn off at -25 C (-13 F) and turn on when it reaches -23 C (-9 F).
