Loop
PID_Cool (loop1)
This variable is used to display the actual cooling loop value. This variable is used by the system to
control the cooling valve and the dampers.
The following parameters of this loop can be modified to adjust the response of the controller.
ProportionalConstant, default value = 2°C
IntegralConstant, default value = 0 seconds
DerivativeConstant, default value = 0 seconds
Bias, default value = 0%
ID Units Valid Range Default Value
PID1 Percent (%) 0 to 100% N/A
PID_Heat (loop2)
This variable is used to display the actual heating loop value. This variable is used by the system to
control the heating valve.
The following parameters of this loop can be modified to adjust the response of the controller.
ProportionalConstant, default value = 2°C
IntegralConstant, default value = 0 seconds
DerivativeConstant, default value = 0 seconds
Bias, default value = 0%
ID Units Valid Range Default Value
PID2 Percent (%) 0 to 100% N/A
PID_CO2 (loop3)
This variable is used to display the actual CO2 loop value. This variable is used by the system to con-
trol the fresh air damper.
The following parameters of this loop can be modified to adjust the response of the controller.
ProportionalConstant, default value = 200 ppm
IntegralConstant, default value = 0 seconds
DerivativeConstant, default value = 0 seconds
Bias, default value = 0%
ID Units Valid Range Default Value
PID3 Percent (%) 0 to 100% N/A
PID_Dampers (loop4)
This variable is used to display the actual dampers loop value.
The following parameters of this loop can be modified to adjust the response of the controller.
ProportionalConstant, default value = 10°C
IntegralConstant, default value = 300 seconds
DerivativeConstant, default value = 0 seconds
Bias, default value = 50%
