Hello,

below you find the instructions to connect the MAC-333IF-E:

How to provide DC output on line L1

For Daikin or Mitsubishi Electric Non—VRV/VRF equipment, DC voltage supply by CoolMasterNet might be required for proper operation. Before enabling DC output from CoolMasterNet make sure there is no DC voltage on HVAC communication line. If no DC voltage detected: Daikin 14-16V DC, Mitsubishi 28-30V DC, do following:
  • Disconnect CoolMasterNet from power and HVAC line.
  • Change the dip switches S1 and S2 as shown below.
Daikin


Mitsubishi Electric

  • Turn ON the power for CoolMasterNet and connect it to HVAC line.
  • Issue below command:
and power reset CoolMasterNet.

Good Morning,

If there is voltage on the bus, DIP switches S1 and S2 must not be enabled.
