19.PARAMETER TABLE
1.3.x.2
Control type:
The discharge control can be carried out by pressure or temperature.
In pressure control, the pressure sensor, pressure setpoint and pressure hysteresis will be considered.
Temperature control will consider the temperature sensor, temperature setpoint and temperature hysteresis
Note:
Calculation of the subcooling only available when the control type is by pressure.
1.3.x.3
Pressure setpoint:
Pressure value for controlling the discharge in which the system shuts down all fans.
1.3.x.4
Economy pressure setpoint:
Alternative pressure setpoint value, usually less than the pressure setpoint (
1.3.x.3
).
1.3.x.5
Pressure hysteresis of digital outputs:
It is pressure range for controlling the fans linked with the digital outputs. This pressure value is related to the setpoint that defines the actuation points
for each fan (activation interval = se hysteresis).
1.3.x.6
Analog output Hysteresis:
It is pressure range for controlling the fan linked with the analog output. The modulation of the analog output is within this range related to the setpoint.
This parameter is valid only for Linear and Rotation control modes.
1.3.x.7
Lower dead zone differential (pressure):
Pressure differential, below the setpoint that allows the compressors to be shut off. Used in the Dead zone and Dead zone with rotation control modes.
1.3.x.8
Upper dead zone differential (pressure):
Pressure differential, above the setpoint that allows the compressors to be actuated. Used in the Dead zone and Dead zone with rotation control modes.
1.3.x.9
Minimum pressure setpoint:
Lowest possible value for setpoint adjustment. The purpose is to prevent unreasonably low pressures from being regulated by mistake from the normal
and economy setpoint.
1.3.x.10
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.
1.3.x.11
Temperature setpoint:
Temperature value for controlling the discharge in which the system shuts off all fans.
1.3.x.12
Economy temperature setpoint:
Alternative temperature setpoint value, usually lower than the pressure setpoint (
1.3.x.11
).
1.3.x.13
Digital outputs Hysteresis:
It is the temperature range for controlling the fans linked with the digital outputs. This pressure value is related to the setpoint that defines the actuation
points for each fan (actuation interval = se hysteresis).
1.3.x.14
Analog output hysteresis:
It is the temperature range for controlling the fan linked with the analog output. The modulation of the analog output is within this range related to the
setpoint. This parameter is valid only for Linear and Rotation control modes.
1.3.x.15
Lower dead zone limit (temperature):
Lower limit whose purpose is to avoid that, by mistake, excessively low temperatures are regulated from the normal and economy setpoint.
1.3.x.16
Upper dead zone limit (temperature)
Upper limit whose purpose is to avoid that, by mistake, excessively high temperatures are regulated from the normal and economy setpoint.
1.3.x.17
Minimum temperature setpoint:
Lowest possible value for setpoint adjustment. The purpose is to avoid that, by mistake, excessively low temperatures are set from the normal and
economy setpoint.
1.3.x.18
Maximum temperature setpoint:
Highest possible value for setpoint adjustment. The purpose is to avoid that, by mistake, excessively high temperatures are set from the normal and
economy setpoint.
