Samsung offer two choices of control for AHU, one for the splits range (CAC) and one for the VRF (DVMS) 2-pipe range. These modules are fitted adjacent to the AHU (plantroom) and wire directly into the CAC outdoor unit. For VRF applications the module links to the outdoor unit via 2-core screened data cable. Both modules allow operation via wired controller or via 0-10V input from BMS. On CAC installations, the wired controller can be mounted within the conditioned space and configured to detect room temperature.
Expansion valves are required to be fitted on VRF models and these are included as part of the AHU interface model number quoted.
