Control system
The control system is designed for AHU with AC or EC motors, ventilation units with a heat exchanger, supply and extract air fans, electric heaters or water heaters, and air valves. The control system includes an electronic plate mounted in the control unit and a remote control with a touch screen. To the electronic plate can be connected 4 temperature sensors to ensure efficient and accurate control. Also, the user can program AHU work by time intervals. All settings and measured values about ventilation units can be reached on the automation control panel with a touch screen. This control system has one of the few modified versions. Other versions of control systems can be modified according to the client's technical data of the recuperation system, i.e., exchanger type, with electric heater, preheater, or water heater, "BYPASS type", etc.
