Introduction

The μC 2 is an electronic controller for the complete management of chillers, heat pumps, condensing units and air/
air units with one circuit and 2 hermetic compressors. The expansion board (code MCH200002*) allows the mana-
gement of up to 2 circuits and 4 hermetic compressors.

Characteristics of the connectors

The connectors can be purchased separa- Contact code and cross-section of the connection cables

Parameter programming key option

With the controller OFF, insert the key PSOPZKEY00 in the connector KEY/SPV. Connect and disconnect the serial
and programming key options with the 12-pin connector (relay) removed.
Note: the configuration jumper must be inserted in position A (technical leaflet MCH200485*)

Supervisor option

Connect the serial option (code MCH200485*) to the connector KEY/SPV.

Warnings

• If using a single power transformer for the μC SE and the accessories, connect all the G0 terminals on the various
2
controllers or boards to the same terminal on the secondary, and all the G terminals to the other terminal on the se-
condary, to avoid damaging the instrument;
• For use in residential environments, a shielded cable (conductor + shield) is required for the tLAN connections (EN
55014-1);
• Avoid short-circuits between V+ and GND so as to not damage the instrument:
• Separate the power cables (relay outputs) from the probe, digital input and serial cables;
• Use the power transformer exclusively dedicated to the electronic controllers.

Protection against electric shock and warnings for maintenance

Disconnect the power supply before working on the board during the assembly, maintenance and replacement ope-
rations.
The system made up of the control board (MCH200*03*) and the other optional cards (MCH200002*, MCH200485*,
MCHRTF****, CONVONOFF*, CONV0/10A*, EVD000040*) represents a control device to be incorporated in class I
or class II equipment. The class of protection against electric shock depends on how
ted into the unit made by the manufacturer.
The protection against short-circuits, due to defective wiring, must be guaranteed by the manufacturer of the equip-
ment that the control device is built into.
