Cycle Time (heat output)
This setting can be ignored for analog control outputs.
1. 0
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%
0. 1
increments.
OFF
Integral Action Time (heat output)
1
Set the required time between 1 and 7200 in 1 second increments (7200 seconds =
OFF
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
0. 0
100.0% of the engineering range span in 0.1% increments.
Cycle Time (cool output)
This setting can be ignored for analog control outputs.
1. 0
