MECHANICAL TEMPERATURE CONTROLS
DANFOSS TEMPERATURE CONTROL
ADJUSTMENT FOR HIGH ALTITUDE
APPLICATIONS:
REQUIRED TOOLS:
• Allen Wrench (5/64")
• Torx Screw (T-7)
TERMS:
Cut-out - Temperature sensed by the controller that shuts the
compressor off.
Cut-in - Temperature sensed by the controller that turns the
compressor on.
STEP 1 - Unplug cooler.
STEP 2 - Remove the screws that secure the temperature
control to the inset box.
STEP 3 - To make these adjustments it may be necessary to
remove the temperature control from the housing.
NOTE: You may have to remove the wires attached to the
control. Take note as to which wire is on which spade terminal.
STEP 4 - Pull out gently from cabinet.
NOTE: Mechanical temperature controllers are affected when
functioning at high altitude. The cut-in and cut-out temperatures
will be colder than when the controller functions closer to sea
level.
STEP 5 - For high elevation installations, it may be necessary
to "warm-up" the set points. To make the adjustment, insert
the appropriate tool in each adjustment screw and turn 1/4 of
a revolution clockwise (to the right). This procedure will adjust
both the cut-in and cut-out about 2˚F warmer. Do not turn
more than one (1) full turn.
STEP 6 - Make sure to reconnect the wires to the proper
spade terminal when reinstalling.
