To manage VRF systems, we offer a wide range of wired controllers that diversion can be divided into three main groups: the control for indoor units - you can also divide them into individual (for one unit) and group (for multiple units), for monitoring operating parameters outdoor units, for especially focused tasks - specialized controllers. If necessary, on the basis of controllers can build a more developed and complex control system with data output on a server BMS, Internet, dedicated management server.
