This function selects the heater circuit. Each heater circuit has a unique Heater Number
in a form of M-N. M is the Module Number of the Control Module and N is the heater
circuit within the Control Module. Press [VALUE ] or [VALUE ] and then press
[STORE] to select a heater circuit. For convenience and to reduce human error, the
Heater Name is also displayed.

This function sets the Heater Name. It provides a unique, identifiable tag or label for
the heater circuit. The Heater Name consists of 16 alphanumeric characters that you
enter one at a time from left to right. The cursor indicates which character is being
selected. Press [VALUE ] or [VALUE ] to change the character. Move to the next
character by pressing [STORE]. Continue in this way until all 16 characters are entered.
Press [STORE] in the last character position to save the Heater Name.

This feature sets the response of the heater circuit to the Control Module’s Master
Override input. The Master Override input responds to a contact closure. If the
Master Override is set to
off
or the Master Override inputs are shorted, control of the
heater circuit operates normally based on the Heater Control Temperature and the
Heater Setpoint. If the Master Override is set to
on
and the Master Override inputs
are open, the heater circuit is opened regardless of the Heater Control Temperature.
This feature allows selected circuits to be turned off for load shedding or for an
ambient temperature override. If the Heater Setpoint is set to
off
or
none
and the
Master Override is set to
on
, the Master Override inputs will have full control over the
heater circuit.

This function minimizes temperature overshoot and undershoot for tighter temperature
control. For critical temperature maintenance applications you can obtain more accurate
control by using this feature. However, the time to reach Heater Setpoint may be
longer. With Proportional Control set to
on
, as the Heater Control Temperature
approaches the Heater Setpoint, the percent duty cycle of the heater is reduced. With
Proportional Control set to
off
, on-off control is used.
