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 connection
“1–4” opens 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
the indicator) allows the unit to be manually actu-
ated (with a screwdriver) during system tests.
Actuation and Reset
Terminal 1 is the “common” terminal, 4 is NC
(above setpoint), and 2 is NO. When the sensed
temperature falls below setpoint, connection “1–4”
opens and connection “1–2” closes (see diagram
below). 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
setpoint.
