PWM - Pulse-Width Modulation) is a generated frequency signal from a selected fixed range called Duty Cycle (percentage of specified period of time when the signal is active), i.e., the duty ratio between the high state and low state of the signal.

The steering has a multilanguage menu.
Functions performed by the controller:

- control of the operation of pumps (or a pump and a valve)
- supervision and handling of the solar system operation for nine configurations of the system
- protection against overheating and freezing of the collector
- the possibility of connecting an additional device: circulating pump, electric heater or sending a signal to the CH boiler to fire it up

Equipment of controller:
- large clear LCD display
- collector's temperature sensor
- heat accumulator's temperature sensor
- casing made of high quality materials resistant to high and low temperatures
