Page Header – Control Page

Cycle Time (heat output)
This setting can be ignored for analog control outputs.

Set the required cycle time for time proportioning control, from 1.0 to 300.0 in
0.1 second increments (300 seconds = 5 minutes).

Proportional Band (heat output)

Set the proportional band value required, between 0.1 and 999.9% in 0.1%
increments.

Integral Action Time (heat output)

Set the required time between 1 and 7200 in 1 second increments (7200
seconds = 120 minutes). 'OFF' is selected below 1 and above 7200.

Manual Reset (heat output)

Set the required proportional band offset on the lower display, between 0.0 and
100.0% of the engineering range span in 0.1% increments.

Cycle Time (cool output)
This setting can be ignored for analog control outputs.

Set the required cycle time for time proportioning control, from 1.0 to 300.0 in
0.1 second increments (300 seconds = 5 minutes).

Proportional Band (cool output)

Set the proportional band value required, between 0.1 and 999.9% in 0.1%
increments.

Integral Action Time (cool output)

Set the required time between 1 and 7200 in 1 second increments (7200
seconds = 120 minutes). 'OFF' is selected below 1 and above 7200.
