The Multifunctional Actuator, 3-Fold, 6A, Flush Mounted (Referred to as Multifunctional actuator) is a module that integrates multiple relay output functions, including switch output, curtain output, fan output or valve output, in addition to dry contact input and LED output indication functions.

The corresponding output function can be configured according to actual application requirements.

This module is compact and small in design, Flush mounted, and can be installed in a conventional 80 mm or 86mm wiring box. The output adopts screw terminal to realize electrical connection, and the bus connection is directly connected via KNX terminal. The additional power supply is not required except KNX bus.

The function of the Multifunctional Actuator is summarized as follows:

Switch output

which can connect some electrical loads, such as lighting, sockets and heating control. There are 3 outputs, one output occupies one relay control, and each output has electronic switch control. The module offers the following functions: 

• Switch  Time function: on/off delay 
• Time function: flashing switch, for lamps of aging test 
• Time function: staircase lighting, for switch on the staircase lighting and after the duration time the lighting can be turned off automatically. It is better if the function is used together with motion detector. 
• Provide 8 scenes, recall and storing via a 1byte object 
• Logic operation: AND, OR, XOR, GATE function, up to three logic inputs 
• Status response, for know the current output state in the visualization 
• Forced operation, two data types: 1bit/2bit, for force action on or off, with the highest priority 
• Heating valve control K-BUS® KNX/EIB Multifunctional Actuator, 3-Fold, 6A, Flush Mounted 2 
• Set the relay contact position after bus voltage recovery 
• Set the relay contact position after bus voltage failure

Curtain output

which can connect with motor blinds, awnings, roller blinds, vertical blind, etc. There is 1 outputs with AC motor or dry contact controlling motor. The output contacts for the directions UP and DOWN. The pause on change in direction can be set via the parameters. The curtain output occupies two relays per channel. The specific functions are summarized as follows: 

• Movement UP/DOWN 
• Stop/Louvre adjustment 
• Move to position 0……100% 
• Adjustment Louvre to position 0……100%(only “Venetian Blind” working mode) 
• Set 8 scenes, store or recall via a 1byte object 
• Automatic sun protection 
• Safety function 
• Status response, query and reply the current shutter/blind position and operation mode to the bus, thereby indicating the status in the visualization device 
• Two working mode: Venetian Blind and Shutter

Fan control

can be connected to a single-phase fan, supports up to 3 levels of fan speed adjustment, the output contacts are the same as the switch output. The function is summarized as follows: 

• Support the fan with 1-2-3 level fan speed 
• The fan has two operating modes: step switch and changeover switch 
• Forced operation: The fan speed is only allowed within the allowed fan speed range, with the highest priority 
• Automatic operation: Automatically run the fan speed according to the control value. The control value is obtained by the sensing device on the bus, and the minimum running time of the fan speed can be set. 
• Normal operation: manually control the operation of the fan, such as through the K-BUS® KNX/EIB Multifunctional Actuator, 3-Fold, 6A, Flush Mounted 3 operation panel, etc. 
• Fan with multi-level fan speed can set start-up characteristics 
• Single-level fan speed fan can set on/off delay or minimum running time 
• Status feedback, such as automatic operation status, fan switching status, fan speed, etc. 
• Operational control of bus power-up or power-down behavior

Valve control 

can be used to connect 2-pipes or 4-pipes coil system, there are three types of valve control for 2-pipes: “3 point, open and close”, “continuous, PWM” and “2 state-ON/OFF”. The cooling valve and heating valve respectively use separate relay output for 4-pipes, but only support two valve control type: “continuous, PWM” and “2 state-ON/OFF” .

The “3 point, open and close” type controls the opening of the valve according to the control value of the valve. It can completely open or close the valve, and can also stop the valve in an intermediate position. This type of control is suitable for driving three-wire valves.

The “continuous, PWM” type can only make the valve fully open or completely closed. The valve is cyclically operated according to the control value (1byte) and PWM cycle. The valve switch is divided into normally open or normally closed. This control type is suitable for driving two-wire system. Valve.

The “2 state-ON/OFF” type is similar to the PWM switch type, and can only be fully opened or completely closed. The difference is that it is directly turned on or off according to the control value (1 bit) on the bus. It is usually suitable for the case where the switch valve is controlled according to the temperature difference. And suitable for driving two-wire valves.

The function is summarized as follows: 

• Supports three valve control types 
• Monitor the control values on the bus to send fault status 
• Valve characteristic curve correction (only for valve type of 3 point, open and close) 
• Automatic valve adjustment ( only for valve type of 3 point, open and close) 
• Disable/enable heating or cooling valves 
• Valve position status feedback or query 
• Manual or automatic purge of the valve, sending the purge status

Dry contact Input detection

can be connected with dry contact panels or sensor devices, and supports up to 6 inputs. The functions are summarized as follows: 

• Switching and dimming 
• Blind control 
• Value output 
• Recall and Stored scene function 
• Shift register function 
• Multiple control 
• Delay sending(e.g. switching value, dimming value)

LED Output indicator 

can support common-cathode or common-anode LED indicator connection, and the voltage can be 5V or 12V. Up to 6 outputs. The functions are summarized as follows:

•  Switch status indication 
• Compare with the threshold, then output indication 
• Always on
