INSTALLATION INSTRUCTION<br />
Danfoss Temperature Control Adjustment for High Altitude Applications<br />
Cut-out - Temperature sensed by the<br />
controller that shuts the compressor<br />
off.<br />
Cut-in - Temperature sensed by the<br />
controller that turns the compressor on.<br />
Instructions:<br />
___________ STEP 1 ___________<br />
Mechanical temperature controllers are<br />
affected when functioning at high altitude.<br />
The cut-in and cut-out temperatures<br />
will be colder than when the controller<br />
function closer to sea level.<br />
___________ STEP 2 ___________<br />
For installations above 2,000 ft., it may<br />
be necessary to “warm-up” the set<br />
points. To make the adjustment, insert<br />
the appropriate tool in each adjustment<br />
screw and turn 1/4 of a revolution<br />
clock-wise (to the right). This procedure<br />
will adjust both the cut-in and<br />
cut-out about 2˚F warmer.<br />
___________ STEP 3 ___________<br />
Make sure to re-connect the pink wires<br />
to the proper spade terminal when<br />
re-installing.<br />
