5. Status LEDs
There are 2 status LEDs on the Procon A1M. The LED indications are as follows:
LED Name
Colour
Functionality
LED1 Green
Lit when A1M is powered, flashing indicates valid communication
with the indoor unit.
LED2 Green
Lit when A1M is powered, flashing indicates valid Modbus
communication.
Please note: if one or both of the LEDs are permanently on, this indicates that the Procon A1M is powered
successfully, but no communication traffic is present. In this case please check the Slave ID settings, and ensure the
CN105/CN92 connector is seated correctly.
