In the basic setting unit type SupraBox COMFORT (SBC) the default values
were called up. For the control voltage and speed the manufacturer values
are stored in the memory. The selection Boost with the higher values as
maximum values for the control voltage and speed is set in this display. The
Boost Modus via heat recovery affects the efficiency.
The counter flow heat exchanger is monitored due to icing with the help of a
pressure difference control device. During the setup it can be defined which
de-frosting strategy should be used. For the program routine defrost se-
quence the speed of the supply fan is reduced by 30% after the pressure
difference control device is released. The release and the duration of the
fan operation in imbalance and a compulsive break for the automatic mode
are set in this display.
The automatic mode of the fans can be set separately. The possibilities are:
-
0-10V Signal
-
Volume flow
-
Pressure
-
Slave operation
The effect of these setting is the application of the corresponding sensor and
the control method.
The automatic mode of the fans can be set separately. For the setting pres-
sure the display appears.
For the dynamic control method (PI-Control) the proportional part and the
integration part is set in this display for the measuring range of the sensors.
