In order to connect the air conditioning units SAMSUNG (the DVM, CAC, FJM series), you should use the communication interface MIM-B04A, MIM-B13A/B mounted in the outdoor units of air conditioning equipment, which you should connect to the communication channel CH2 (CH3, CH4) of the Foxtrot basic module. Up to 16 outdoor units with a total of 200 connected indoor air conditioning units can be connected to one communication interface (RS-485). The communication converters must be properly addressed and connected (see the Fig.); no other configuration is needed. The necessary condition is a proper connection of indoor and outdoor air conditioning units according to the manufacturer's specifications.

In order to operate the units, there is an FB library available. The Foxtrot system features allow monitoring the units (indoor unit errors, filter status, temperature, fan speed, mode, keypad lock in the local thermostat, plasma filter, etc.) and controlling the units (the fan speed, the operation mode, the required temperature, the active switching of the thermostat, the thermostat keys lock, the plasma, etc.).

 

Converters and corresponding outdoor units can be used for the connection:

MIM-B04A (Support of maximum 48 internal units): DVM

Mini DVM (R22)

CAC

 

MIM-B13A/B13B (Support of maximum 64 internal units): DVM PLUS II/III

DVM PLUS II/III HR

FJM

Super FJM

Mini DVM (R410A)

Notes:

  1. The CH2 communication interface of the CP-1000 basic module in the example is fitted with the MR-0114 submodule; for more information see the documentation.

  2. The RS-485 interface connecting cable between the CP-1000 and the outdoor units of SAMSUNG interface modules is a standard RS-485 cable, a shielded twisted pair, with 0.35mm minimum diameter.

  3. The maximum length of the cable is about 1,000 m; it is necessary to observe the installation rules for the RS-485 cable.

  4. A maximum number of outdoor units (with MIM-B04A, MIM-B13A/B interface) is 16.

  5. Detailed information on connection of the indoor and outdoor units and their installation is listed in the company materials on SAMSUNG air conditioning units.
