    The actuator is a modular installation device with a module width of 4 space units in ProM Design for installation in the distribution board. The connection to the ABB i-bus is established using the front side bus connection terminal. The Fan Coil Actuator does not require an auxiliary voltage supply. The assignment of the physical addresses as well as the parameterisation is carried out with Engineering Tool Software ETS (from Version ETS2 V1.3a)
