NOTE
Mechanical temperature controllers are affected
when functioning at high altitude. The Cut-in and
cut-out temperatures will be colder than when the
controller functions closer to sea level.
D. For high elevation installations, it may be nec-
essary to "warm-up" the set points. To make
the adjustment, insert the appropriate tool in
each adjustment screw and turn 1/4 of a revo-
lution clockwise (to the right). This procedure
will adjust both the cut-in and cut-out about
2°F warmer.
E. Make sure to reconnect the wire to proper
spade terminal when reinstalling.
