Temperature Control Altitude Adjustment(New Temp. Control) - True GDM Series Technical & Service Manual

INSTALLATION INSTRUCTION
Danfoss Temperature Control Adjustment for High Altitude Applications
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.
Instructions:
___________ STEP 1 ___________
Mechanical temperature controllers are
affected when functioning at high alti-
tude. The cut-in and cut-out tempera-
tures will be colder than when the con-
troller function closer to sea level.
___________ STEP 2 ___________
For installations above 2,000 ft., 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
clock-wise (to the right). This proce-
dure will adjust both the cut-in and
cut-out about 2˚F warmer.
___________ STEP 3 ___________
Make sure to re-connect the pink wires
to the proper spade terminal when
re-installing.
