For Sale: Heinen & Hopman - VDH MC-785 Controller

[seareefer]

The MC 785-SC is an 8-stage step controller, which controls maximal 8 compressors and 8 condenser fans stepping up or down, based on the measured suction and discharge pressure and its setpoints.

To control stepping up or down the controller can be set to the following choices:
Compressor control: On/off control, with or without valve lifting
(x-stage compressors) or Frequency control
Condenser control: On/off control or Frequency control
The controller can also step up or down a compressor or condenser, based on the total operation hours or based on the power of the compressors or condensers. It is also possible to disable compressors or condensers for maintenance or when a failure occurs.

All inputs and outputs can be assigned thru setting internal parameters, so an efficient use of the inputs and outputs is possible. If not enough inputs or outputs are available on the controller these can be extended by use of extra LMS Modules connected at the I2C-bus.

Pictures to follow soon. PM for further details.
