Switching the unit ON/OFF;
2.
Maintenance of set supply temperature by means of automatic regulation of the electric heating coil capacity;
3.
Electric heater overheating protection with two thermostats;
4.
Rotary heat exchanger control;
5.
Supply and exhaust fans control and monitoring;
6.
Supply and exhaust air controlling damper actuating;
7.
System shutdown on signal from fi re fi ghting system.
The controller has the following functions: electric heater and rotary heat exchanger control, air damper opening and closing.
The supply air temperature is maintained at set point during the fan operation by means of electric heater power regulation
performed by triac units. In case of the unit shutdown the automatic control system provides air supply to the electric heating elements
within n minutes (adjustable parameter E-01) for heat removing.
The automatic control system provides automatic restart of the fans after power failure. This function is activated and adjusted from
