2.3.8 TEMP OFFSET
Values: ‐10.0 °C to +10.0 °C
Default value = 0.0 °C
Description: Offsets the control sensor value for both the display and control algorithm.
2.3.9 ALARM 1 TEMPS
Values: ‐20 to 199 or OFF for HIGH setting; ‐20 to 199 or OFF for LOW setting
Default value for HIGH = 60
Default value for LOW = ‐20
Description: This sets the high and low temperatures for signaling an alarm based on the control sensor
temperature. Adjustments are in 1 °C increments, and the high setting must be higher than the low
setting. If the HIGH setting is increased past 199, OFF is indicated and no alarm will be signaled based on
the control sensor for over‐temperature conditions. If the LOW setting is decreased past ‐20, OFF is
indicated and no alarm will be signaled based on the control sensor for under‐temperature conditions.
Note: If the controller senses an open circuit or a short circuit on the control sensor, the controller will
automatically turn off output power, regardless of the ALARM 1 FUNCTION setting.
2.3.10 ALARM 1 FUNCTION
Values: KEEP OUTPUT ON or TURN OFF OUTPUT
Default value = TURN OFF OUTPUT
Description: This setting determines what action will be taken when there is an alarm condition on the
control sensor. When KEEP OUTPUT ON is selected, output power to the TE device stays on during the
alarm condition, and the alarm 1 signal on JP5‐10 is activated. When TURN OFF OUTPUT is selected,
output power to the TE device is turned off, and the alarm 1 signal on JP5‐10 is activated.
The ALARM 1 and ALARM 2 outputs on JP5‐10 AND JP5‐11 will momentarily pulse on and off
several times in the first second after the controller is turned on. This happens as the
microprocessor in the controller configures itself, regardless of any alarm condition.
2.3.11 ALARM 2 TEMPS
Values: ‐20 to 199 or OFF for HIGH setting; ‐20 to 199 or OFF for LOW setting
Default value for HIGH = 60
Default value for LOW = ‐20
Description: This sets the high and low temperatures for signaling an alarm based on the optional,
secondary sensor temperature. Adjustments are in 1 °C increments, and the high setting must be higher
than the low setting. If the HIGH setting is increased past 199, OFF is indicated and no alarm will be
signaled based on the secondary sensor for over‐temperature conditions. If the LOW setting is decreased
past ‐20, OFF is indicated and no alarm will be signaled based on the secondary sensor for under‐
temperature conditions.
Note: If the controller senses an open circuit or a short circuit with respect to the thermistor, the
controller will signal an alarm condition (presuming it is not set to OFF). In addition, if the controller
senses an open thermistor circuit, T2 will not be displayed in the primary screen.
2.3.12 ALARM 2 FUNCTION
Values: KEEP OUTPUT ON or TURN OUTPUT OFF
Default value = TURN OUTPUT OFF
