Fans, blower convectors and fan coil units are used for distributed heating and cooling applications. They
are installed rooms and powered via central heating and cooling systems. Using fans, room temperature
can be quickly adjusted to suit individual preferences.
Fan Coil Actuators switch multi-level fans with up to three fan speeds via floating contacts. Three inputs
are available, for monitoring of a window contact and the dew point or for connecting temperature sensors.
An additional contact is possible, for example, for control of an electric heater.
Fan Coil Actuators vary in the way they control the valves.
The Fan Coil Actuators FCA/S 1.1.x.2 have two outputs for control of motor power operated or thermal
heating and cooling valves.
The Fan Coil Actuators FCA/S 1.2.x.2 have two outputs for control of analog heating and cooling valves.
