INSTALLATION INSTRUCTIONS
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.
WHEN TO MAKE AN ADJUSTMENT TO A MECHANICAL TEMPERATURE CONTROL
OPERATION INSTRUCTIONS:
REQUIRED TOOLS:
• Jewelers Screw Driver (Small Screw Driver)
GE CONTROL INSTRUCTIONS:
The scale to the right may be used as a guide for measuring
degrees of rotation required for altitude correction. See Figure 1.
The arrows indicate direction of screw rotation. Turn calibration
screw clockwise to obtain warmer operating temperatures.
NOTE: Each 1/4 turn of the calibration screw is equal to
approximately 2 degrees F. Do not make more than 3/4 turn.
After making adjustment, measure temperature during three
cycles before adjusting again.
NOTE: Only adjust the screw
(small flathead) on the face of
the control (next to the cam).
See Figure 3.

We advise to make a mechanical temperature control adjustment only for a high altitude location.
