Review Temperature Controller's Settings for accuracy
The condensing unit may be equipped with its own controller and display. This controller
is only for the condensing unit and does not control the temperature of the case. Do not
adjust settings on this controller. Only a qualified service technician should attempt to
change settings on this controller
The Danfoss controller located on the switch panel (see page 16) is for case temperature
control. Note that when the Danfoss controller is not calling for cooling, the display on the
condensing unit controller will go off. This is considered normal operation.
