INSTALLATION / OPERATION INSTRUCTIONS
STEP 4
For high elevation installations,
it may be necessary to "warm-up"
the set points. To make the adjust-
ment, insert the appropriate tool in
each adjustment screw and turn 1/4
of a revolution clockwise (to the
right). This procedure will adjust
both the cut-in and cut-out about
2°F warmer.
STEP 5
Make sure to reconnect the pink
wire to the proper spade
terminal when reinstalling.
