3 About the kit
The EKMBPP1 kit is a Modbus interface to monitor and control the VRV
and Sky Air ranges of air conditioners, as well as the VAM and VKM
ventilation units. The interface is compatible with units that have a P1P2
remote controller connection, allowing control of up to 16 units in a
single group. Functionality includes:
▪ Group control of unit settings (setpoint, fan speed, operation mode,
airflow direction, on/off state)
▪ Control over the lock state of individual remote controller buttons
▪ Control limiting (limit possible user adjustments to specified ranges)
▪ Control over settings specific to VAM and VKM units (fan speed,
damper control, on/off state)
▪ Unit monitoring (group and individual readback of unit data)
▪ Smart Grid control on Sky Air ranges.
