Specifications
Maintenance
No routine maintenance is required. Each compo-
nent is designed for dependable, long-term reliabil-
ity, and performance. Careful installation will also
ensure long-term reliability and performance.
Setpoint Adjustment
The setpoint is the temperature at which contacts
“11–14” and “21–24” open as the unit senses a fall in
temperature. To adjust the setpoint:
• Turn the range adjustment screw CW to decrease
the setpoint.
• Turn the range adjustment screw CCW to
increase the setpoint.
Testing
A manual test lever located under the cover (below
and to the left of the controller spring) allows the
unit to be manually actuated during system tests.
Actuation and Reset
Terminals 11 and 21 are “common” terminals, 14
and 24 are Normally Closed (above setpoint), and
12 and 22 are Normally Open (see the diagram
below). When the sensed temperature falls below
setpoint, connections “11–14” and “21–24” open and
connections “11–12” and “21–22” close.
The switch
latches in this position until the sensed temperature
rises 5° F (3° C) above setpoint and the controller is
reset either (depending on the model) automatically
or manually by depressing the reset button located in
the top of the controller case.
The controller cannot be manually reset until the
sensed temperature is at least 5° F (3° C) above the
setpoint.
