1 General description
DKAC-I and MBAC-I (Ref. GW630100 / GW631100) devices are climate gateways that control machines of Daikin or
Mitsubishi, according to the reference, so that the user can integrate the control of the temperature, operating modes, speeds
of their fan and which, typically, would be made from the remote control of the unit from weather and ventilation, into KNX
system.
Both references are configured with the same Bes application program.
