For heating, ventilation and air conditioning control. For controlling fan convectors with up to three speeds, as well as for controlling three-step motor drives (continuous/pulse-width-modulated) or two-step thermal drives. The actuator supports 2-pipe and 4-pipe systems.
Two floating binary inputs for window contact and level contact for condensed water container, for example. Connection of 1-speed to 3-speed fans. The multi-function push-button with room temperature control can be used to activate the fan coil actuator. With integrated bus coupler. For installation on DIN rails EN 60715. The bus is connected using a bus connecting terminal; a data rail is not necessary.
Fan control:
- In automatic mode, the fan speeds are controlled dependently by the control value of the multi-function push-button.
- The three fan speeds and automatic mode can be switched via EIB telegram.
- The fan can be controlled either directly or via actuators / suitable dimming actuators.
- Fan speed feedback is possible via corresponding status feedback objects e.g. status LED of the push-button.
- The fan speed as well as the automatic status "(Auto)" can be displayed on the display of the multi-function push-button with TCU.
Valve control:
- Type of controller: PI controller (PWM and continuous).
- Controller mode: Heating and/or cooling with common or separate valve outputs.
- Operating modes: The operating mode is selected in the multi-function push-button with TCU
