    SCMI-01.4 CONTROL MODULE – DESCRIPTION AND INSTRUCTION MANUAL 1. INTRODUCTION The SCMI-01.4 control module is designed for controlling ASGE–xxBI and ASGE-xxBI-3 outdoor inverter units with R32 refrigerant. This module can operate in the autonomous pressure (evaporation temperature) control mode, autonomous temperature control mode for cooling or heating, or as a slave unit.

  • Page 4: Safety Instructions

     The SCMI-01.4 control module may be installed only by a company that has the relevant qualification and is authorized by the manufacturer. This device is designed for mounting on a DIN rail in a dry and dust-free environment.

  • Page 5: Terminals And Wiring The Units

    3. TERMINALS AND WIRING THE UNITS The SCMI-01.4 control module is equipped with 20 screw terminals to connect the external circuits. On one side of the module, there are terminals for supply voltage 230V/50Hz and terminals for NO contacts of the output relays R1 to R3. Terminals on the other side of the module allow you to connect a current output 4-20mA from a relative pressure sensor 0- 18bar, output 0-10V from an external performance control, two 10kΩ...
