Advantages over analogues: Energy savings due to: - optimization of the suction pressure; - shift of the setpoint during the night; - floating condensing pressure; - load restriction.

The development stage readiness: Introduced in production

Description of the development:
()
The controller is provided via the Modbus network data transfer, and it can be connected to the system device type AK-SC 355, AK-SM 800. It can be used incrementally (step) fan control relay with the controller or control their speed using the analog output controller. For the speed control can be used frequency drive VLT types or fazorezka. When working at night the fan noise can be reduced. For this purpose, limited productivity capacitor by a predetermined amount.
