7.2.- Floating Condensation (COND_9)
Unlike constant condensation, Floating Condensation adjusts the condensation Set Point according to the
Ambient air temperature and other installation parameters. The aim of this is to reduce the installation's
electricity consumption. To achieve efficient regulation of the discharge pressure, the user needs to enter the
D
T for the condenser used (
CODF_2
) and the minimum condensation temperature (
CODF_1
). Both
parameters are closely linked to the installation: condenser type, expansion valve, refrigerant, etc.
If there is an error in the Ambient air probe reading, a constant condensation pressure/temperature will be
used, defined by parameter
COND_1.
This function cannot be enabled if the type of refrigerant selected is GENERIC (parameter
CONF_7
).
7.3.- Energy Saving (AENR_1)
The Energy Saving function enables the Evaporation SET POINT to be adjusted during a specified time period
in order to reduce electricity consumption.
Examples of applications:
ELECTRICITY TARIFF:
To lower the evaporation Set Point when kWh costs are at their lowest.
INACTIVITY OF COLD ROOMS:
To increase the evaporation Set Point in those periods when
there is little activity in the installation.
It is necessary to set the following user parameters to adjust this function:
AENR_1, AENR_2, AENR_3:
Schedules for activation of Energy Saving
AENR_4:
Duration of Energy Saving
AENR_5:
Evaporation Set Point variation during Energy Saving
7.4.- MANUAL/AUTOMATIC selector
The operation of the DUOControl controller depends on the status of this selector. When it is in the
AUTOMATIC position the controller regulates the compressors and fans (or inverter) automatically according
to the control algorithms and the specified user adjustments.
When this is switched to the MANUAL position, all the compressors and fans are progressively stopped until
the refrigerating facility is shutdown. This function enables:
The installation to be shutdown in a controlled manner to permit modification of critical setting
parameters (programming assistant).
The operation of the compressors and fans to be checked manually.
