4.14.15. COOL - Selecting cooling fluid
Acronym Scrolling message Submenu Attributes
COOL PID.1 (or PID.2) COOLING MEDIA PID R W
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 = Air (relative gain H.PB/C.PB = 1)
OIL = Oil (relative gain H.PB/C.PB = 0,8)
H2O = Water (relative gain H.PB/C.PB = 0,4)
4.14.16. C.SP - Cooling setpoint with respect to heating setpoint
Acronym Scrolling message Submenu Attributes
C.SP PID.1 (or PID.2) COOLING SETPOINT RELEVANT TO HEATING SETP PID R W
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: %, of full scale of main or auxiliary input
Options: -25.0...25.0
4.14.17. C.PB - Proportional cooling band or hysteresis in ON-OFF control
Acronym Scrolling message Submenu Attributes
C.PB PID.1 (or PID.2) COOLING PROPORTIONAL BAND OR ON/OFF HYST PID R W
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 Scrolling message Submenu Attributes
C.IT PID.1 (or PID.2) COOLING INTEGRAL TIME PID R W
The parameter shows and sets the integral cooling time.
Unit of measurement: Minutes
Options: 0.00...99.99
4.14.19. C.DT - Derivative cooling time
Acronym Scrolling message Submenu Attributes
C.DT PID.1 (or PID.2) COOLING DERIVATIVE TIME PID R W
The parameter shows and sets the derivative cooling time.
Unit of measurement: Minutes
Options: 0.00...99.99
