PID parameters (cont’d)
oLLC Min. control output for cooling.(0.0%- ouLC). Inactive in Heating/Cooling mode.
ouLC Maximum control output for cooling. (oLLC - 100.0%).
oLtC Minimum output time for cooling. (0.0 to Ct-C or 50 miliseconds if value is 0.0)
ArAnti-Reset Windup (0% to 100% of FS). During PID operation if PSEt -
Ar#PSEt#PSEt+Ar then an integral value is calculated otherwise the last
calculated integral value is used. See p6 for graphic example.
If ot.Ar is selected, then proportional band is used in PID process instead of Ar
value.
SuoF Offsets the proportional band from the SV in the PID calculations ("50% of FS)
PoFS PID output offset. Added to PID output. -100.0 to 0 for cooling PID
0.0 to 100.0 for heating PID
-100.0 to 100.0 for heating/cooling PID.
Strn Stability value. Adjustable from 1 to max scale. If tunn=no or Stun, oscillation might
occur. PSEt-Strn#PSEt#PSEt+Strn
O-dbProportional band shifting. Adjustable from +50.0% of FS. This value is added to
PSET value for cooling. If SV for heating =PSEt+SuoF then SV for
cooling=PSEt+SuoF+o-db
Sbou Control output value for duration of Sensor break error
-100.0 to 0 for cooling PID
0.0 to 100.0 for heating PID
-100.0 to 100.0 for heating/cooling PID
To continue controlling the process if sensor breaks, enter a value. Inactive if 0.0

P-Ht Proportional band for heating (0.0% to 999.9% of FS.)
I-Ht Integral time for heating (0 to 3600 seconds)
D-Ht Derivative time for heating (0.0 to 999.9 seconds)
Ct-H Control period for heating (1 to 150 seconds)
For Relay module: 30 seconds
For SSR driver module: 1 or 2 seconds.
oLLH Min. control output for heating.(0.0 to ouLH).Inactive ın Heating/Cooling mode.
oULH Maximum control output for heating. (oLLH to 100%).
oLtH Min. output time for heating. (0.0 to Ct-H or 50 miliseconds when = 0.0)
CCoE Cooling proportional band coefficient. (0.0% to 100.0%). If heating and cooling
PID are used, tunning is performed by the heating output. Therefore (P-CL=P-
HT * CCoE/100) eg. If P-Ht=10.0% and CCoE=50 then P-CL=
10.0*50/100=5.0%. If value is 0.0, coefficient is inactive.
Recommendation: CCoE=100 when cooling with air; 80 with oil; 40 with water
P-CL Cooling proportional band. (0.0% to 999.9% of FS.) eg. If uPL= 1000EC,
LoL=0EC and P-CL=50% then in temperature P-CL=(1000-0)*50/100=500EC
I-CL Integral time for cooling. (0 to 3600 seconds)
d-CL Derivative time for cooling. (0.0 to 999.9 seconds)
Ct-C Cooling control period. (1 to 150 second)
Recommendation: Use an SSR output for control periods shorter than 30s.
These are much better suited for frequent on/off operation than relay outputs.
