  • Page 10: Regulation Algorithms

    Regulation Algorithms The DIN-TSTAT-FCU is a universal fan-coil controller designed for two-pipe HVAC systems. The device controls the fan used for forcing air flow over the water coil and controls the valve used to adjust the water flow rate through the coil. The fan speed of the fan-coil unit is regulated with three speeds: low, medium, and high.
