WHEN TO MAKE AN ADJUSTMENT TO A MECHANICAL TEMPERATURE CONTROL
We advise to make a mechanical temperature control adjustment only for a high altitude location.
HOW TO ADJUST 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.
Follow the Altitude Correction
Table to the right.
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.
