4.14.15. COOL - Selecting cooling fluid

Acronym
COOL PID.1 (or PID.2) COOLING MEDIA
The parameter shows and sets the fluid used for cooling.
The parameter appears if the parameter Cntr = PID.RGn was selected.
Unit of measurement:
Options: FAN
OIL
H2O

4.14.16. C.SP - Cooling setpoint with respect to heating setpoint

Acronym
C.SP PID.1 (or PID.2) COOLING SETPOINT RELEVANT TO HEATING SETP
The parameter shows and sets the cooling setpoint as a percentage change of the heating setpoint.
Negative values superimpose cooling on heating.
Unit of measurement:
Options: -25.0...25.0

4.14.17. C.PB - Proportional cooling band or hysteresis in ON-OFF control

Acronym
C.PB PID.1 (or PID.2) COOLING PROPORTIONAL BAND OR ON/OFF HYST
The parameter shows and sets the proportional cooling band or hysteresis in the ON-OFF control, calculated as a per-
centage of full scale of the main or auxiliary input.
Unit of measurement:
Options: 0.0...999.9

4.14.18. C.IT - Integral cooling time

Acronym
C.IT PID.1 (or PID.2) COOLING INTEGRAL TIME
The parameter shows and sets the integral cooling time.
Unit of measurement:
Options: 0.00...99.99

4.14.19. C.DT - Derivative cooling time

Acronym
C.DT PID.1 (or PID.2) COOLING DERIVATIVE TIME
The parameter shows and sets the derivative cooling time.
Unit of measurement:
Options: 0.00...99.99
