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. 
Follow the Altitude Correction 
Table to the right.
