19.PARAMETER TABLE
1.2.x.1
Control mode:
Selection of compressor control mode. Available modes:
1.2.x.2
Pressure setpoint:
Pressure value for suction control where the system shuts down all compressors.
1.2.x.3
Pressure Economy :
Alternative pressure setpoint value, generally higher than the pressure setpoint (
1.2.x.2
).
1.2.x.4
Hysteresis of On / Off compressors:
It is the pressure range for controlling the On / Off compressors with or without unloaders. This pressure value is related to the setpoint that defines the
actuation points for each compressor (actuation interval = se hysteresis).
Note:
This parameter is not used in the Progressive Algorithm control mode.
1.2.x.5
Hysteresis of the Variable Capacity Compressor (VCC) :
It is the pressure range for controlling Variable Capacity Compressors (VCC).
The compressor modulation is done within this range relative to the setpoint.
Note:
This parameter is valid only for Linear and Rotation control modes.
1.2.x.6
Hysteresis of AP Control Mode:
It is the pressure range that corresponds to all compressors actuated (On / Off and VCC). The reference values for actuation are calculated from the
capacity of each compressor.
Note:
This parameter is used in the Progressive Algorithm control mode.
1.2.x.7
Lower dead zone differential:
Pressure differential below the setpoint that allows the compressors to be shut down. Used in the Dead zone and Dean Zone with rotation Control
modes.
1.2.x.8
Upper dead zone differential:
Pressure differential above the setpoint that allows the compressors to be actuated. Used in the Dead zone and Dead zone with rotation Control modes.
1.2.x.9
Integral time:
When set to a value greater than Off, it enables the Proportional / Integral (PI) control for the compressors. The value of this parameter corresponds to
the time in which 100% of the control error is accumulated (suction pressure - setpoint). This value must be configured according to the characteristics of
each installation. The higher the value, the slower and more stable the system’s behavior. The lower the configured value, the faster and more
oscillatory the behavior is.
1.2.x.10
Minimum pressure setpoint:
Lowest possible value for adjusting the setpoint. The purpose is to prevent unreasonably low pressures from being regulated by mistake from the
normal and economy setpoint.
1.2.x.11
Maximum pressure setpoint:
Highest possible value for setpoint adjustment. The purpose is to prevent unreasonably high pressures from being regulated by mistake from the
normal and economy setpoint.
1.2.x.12
Suction pressure sensor:
Specifies the pressure sensor used for the suction control.
1.2.x.13
Backup pressure sensor:
Specifies the backup pressure sensor used for the suction control.
When configured, this sensor automatically takes the suction pressure reading.
1.2.x.14
Suction temperature sensor:
Specifies the suction temperature sensor (refrigerant).
When configured, it allows monitoring of the suction line overheating.
1.2.x.15
Number of compressors:
Number of compressors used to control suction.
1.2.x.16
to
1.2.x.21
Compressor 01-06 capacity:
Compressor capacity in KW. This parameter is used in Control mode by progressive algorithm.
0 = Linear
1 = Rotation
2 = Dead zone
3 = Dead zone with rotation
4 = Progressive Algorithm (compressors of differente capacity)
0 = Not configured
Sensors options:
1 = Base - S1
