5.2 Electronic Boards

Multi-Temperature Expansion Boards

Each evaporator equipped in a multi-temperature unit is

provided with 2 solenoid valves, which allow to control

evaporators cooling and heating or defrosting operations.

To manage all of this valves unit logic requires these
following

expansion boards.
