Indoor unit cable connection
After cutting off the power of the indoor unit, connect the cable between the AC POWER terminal block of the indoor
unit and the INDOOR POWER terminal block of the Multi Tenant Function Controller.
Connect the cable between the Commnunication/Power terminal block V1/V2 of the indoor unit and the V1/V2 of the
Multi Tenant Function Controller, complying the correct voltage polarity.
If the cable is connected incorrectly, Multi Tenant Function Controller will not work properly. Furthermore, indoor unit
communication error may occur and entire system may stop.
Connect the DC power cable (5 V), which is included in the box, between the DOWNLOAD conenctor of the indoor unit
and the DC 5 V connector of the Multi Tenant Function Controller.
If you cut the DC power cable (5 V) and extend it on your own, it may cause problem on the product.
To check the connection of the cable, disconnect the AC power cable of the indoor unit and supply the AC 24 V power.
If the green LED of the Multi Tenant Function Controller turns on, cable is correctly connected.
If the green LED of the Multi Tenant Function Controller does not turn on, check if the polarity of the V1 and V2 are correct.
For the products with no V1 and V2 terminal block on the indoor units (such as RAC, 2WAY), connect the #1 wire (RED) of
the 4P connector wire, connected to the communication SUB PCB, to the V1. (V2 connection is not required)
