CBF-S - Fan Coil control box [3-step, AC-motor]
Energy consumption is optimised because cooling is managed in one system. For control of fan coil units with EC motors see control box CBF-E.
CBF-S controls the fan motor as well as the valve actuator so as to adjust the quantity of coolant to the unit. Control of the fan coil unit occurs in three steps, corresponding to the three speed positions of the fan coil unit. From CBF-S version B01 all three steps are adjustable via potentiometers. CBF-S is connected to a room climate controller that supplies the control box with voltage feed and control signal.
