Parameter Definition
1. Control Algorithm of the Algorithms set up group is
configured as PID A, PID B, PD+Manual Reset or Three
Position Step.
2. PID Sets of the Control set up group is configured as
4 Sets Keyboard, 4 Sets PV Swithcover or 4 Sets SP
Switchover.
3. Proportion Unit of the Control set up group is
configured as Proportional Band or Gain.
Rate 4 Min 0.00 to
10.00
minutes
This is the same as above except that it applies to
Duplex models for the "COOL" zone of Heat/Cool
applications or for the second set of PID constants.
Reset
Mins/Rpt 4
Reset
Rpts/Min 4
0.02 to
50.00
These are the same as above except that they apply to
Duplex models for the "COOL" zone of Heat/Cool
applications or for the second set of PID constants.
Cycle Time 1
Sec
1 to 120
seconds
Cycle Time 1 (Heat) determines the length of one time
proportional output relay cycle. Defined as "HEAT" cycle
time for Heat/Cool applications.
NOTE: It only appears when Output Algorithms is
configured as Time Simplex, Time Duplex or
Current Time in the Output set up group.
Cycle Time 1 Sec —Electromechanical relays
Cycle Time 2
Sec
1 to 120
seconds
Cycle Time 2 (COOL) is the same as above except it
applies to Duplex models as the cycle time in the
"COOL" zone of Heat/Cool applications or for the
second set of PID constants.
NOTE: It only appears when Output Algorithms is
configured as Time Duplex or Time Current in the
Output set up group.
Cycle Time 2 Sec —Electromechanical relays
