19.PARAMETER TABLE
1.2.x.3
Pressure setpoint:
Pressure value for suction control where the system switches off all compressors.
1.2.x.4
Economy pressure setpoint:
Alternative value for the pressure setpoint, usually higher than the pressure setpoint (
1.2.x.3
).
1.2.x.5
Digital output hysteresis:
Pressure interval for controlling compressors associated with digital outputs. This pressure value is relative to the setpoint that defines the activation
points of each compressor (activation interval = se hysteresis).
Note:
This parameter is not used in the progressive algorithm mode.
1.2.x.6
Analog output hysteresis:
Pressure interval for controlling the compressor associated with the analog output. The analog output is modulated within this interval relative to the
setpoint. This parameter is valid for Linear and Rotation control modes only.
1.2.x.7
Output hysteresis (PA):
Pressure range for controlling compressors associated with digital outputs and the analog output, within which the compressors are activated.
Note:
This parameter is used in the progressive algorithm mode.
1.2.x.8
Lower dead band differential:
Pressure differential below setpoint that allows switching off the compressors. Used in Dead band and Dead band with rotation control modes.
1.2.x.9
Upper dead band differential:
Pressure differential above setpoint that allows activating the compressors. Used in Dead band and Dead band with rotation control modes.
1.2.x.10
Minimum pressure setpoint:
Lowest possible value for setpoint adjustment. It is aimed to prevent an exceedingly low pressure from being adjusted by mistake for the economy and
normal setpoints.
1.2.x.11
Maximum pressure setpoint:
Highest possible value for setpoint adjustment. It is aimed to prevent an exceedingly high pressure from being adjusted by mistake for the economy and
normal setpoints.
1.2.x.12
Suction pressure sensor:
Specifies the pressure sensor to be used for suction control.
1.2.x.13
Backup pressure sensor:
Specifies the backup pressure sensor to be used for suction control.
When configured, this sensor automatically assumes the reading of the suction pressure.
1.2.x.14
Suction temperature sensor:
Address of the suction temperature sensor (refrigerant).
When configured, it allows monitoring the superheating in the suction line.
1.2.x.15
Number of compressors:
Number of compressors used in suction control.
1.2.x.16
to
1.2.x.21
Compressor 01-06 capacity:
Compressor capacity in kW. This parameter is used in the progressive algorithm control mode.
1.2.x.22
to
1.2.x.27
Compressor 01-06 modulation:
Sets the type of compressor drive.
