Set the dial for the desired temperature to be maintained. If the sensed
temperature is below the set-point, power is applied to the heater and the
indicator light next to the set-point dial is illuminated. After the set-point
temperature is reached, the indicator light next to the set-point dial shuts off and
heater power is removed. The control cycles as necessary to maintain the
desired temperature.
Alarm Operation:
The alarm may be used as a high or low alarm, depending on the connections
used.
In the high temperature alarm mode, the alarm light illuminates and the external
device (if applicable) operates when the sensed temperature is above the alarm
point.
NOTE: To verify alarm operation, turn the alarm point dial to a setting lower
than the sensed temperature. Validate the alarm light illuminates. Return dial
to the desired alarm point to continue operation.
In the low temperature alarm mode, the alarm light illuminates and the external
device (if applicable) operates when the sensed temperature is below the alarm
point.

To verify alarm operation, turn the alarm point dial to a setting greater
than the sensed temperature. Validate the alarm light illuminates. Return dial
