• Switching of electrical fan coil units and other eletrical loads for AC 110 / 230 V
• Switching and dimming of lighting
• Switching of electrically driven blinds, shutters and awnings
• Switching of electrothermal valve drives
• Room thermostat for controlling the temperature
• Inputs for polling conventional, floating contacts, and transmitting telegrams to the
• Outputs for controlling LEDs
• Operation in KNX system
• Mounting on DIN rail according to EN 60715 in distribution box
• Outputs can be operated manually
• Feedback in manual operation and in bus operation
• Scene function
• Disabling of individual outputs manually or via bus
• Operating hours counter, except blind function
• Switch-off of unnecessary outputs
• Logic functions
• KNX Data Secure compatible with ETS 5.7.7 or ETS 6.3.0 or higher
• Can be updated with the ETS Service App
• Connection of up to two fan coils with fan levels
• Operating modes for heating, cooling or combined heating/cooling operations
• 2-pipe or 4-pipe operation
• Individual or hierarchical switching of fan levels
• Operation as 1-way NO or 1-way NC contacts
• Logic operation and forced guidance
• Feedback function
• Central switching function with collective feedback
• Time functions: switch-on delay, switch-off delay, staircase lighting timer with switch- off warning
• Suitable for 110 / 230 V AC motors
• Blind/shutter position directly controllable
• Slat position directly controllable
• Feedback of movement status, blind/shutter position and slat position
• Forced position through higher-level controller
• Safety function: rain alarm, frost alarm, 3 independent wind alarms
• Sun protection function
• Switching operation or PWM operation
• Valve drives with characteristics "normally open" or "normally closed" can be controlled
• Overload-protected, short circuit-protected
• Integrated room temperature control with setpoint specification
• Controller function for heating and cooling
• Protection against jamming valves
• Emergency operation in case of bus voltage failure for summer and winter
• Forced position
• Various setpoints for forced position or emergency operation in case of bus failure for summer or winter
• Cyclical monitoring of the input signals can be parameterised
• Automatic or manual setting of the dimming principle suitable for the load
• No-load protection
• Electronic short-circuit protection
• Electronic over-temperature protection
• Signal in the event of a short-circuit, power failure and overload
• Parameterisable switch-on and dimming behaviour
• Time functions: switch-on delay, switch-off delay, staircase lighting timer with switch- off warning
• Power failure longer than approx. 5 seconds causes the dimming outputs to switch off. Depending on the parameter setting, the connected load is calibrated after voltage return.
• Power extension possible by connecting dimming outputs in parallel
• Connection of floating contacts, such as push-buttons, switches or reed contacts
• Polling with a pulsed current avoids contact contamination (formation of an oxide layer) on the connected contacts
• Operating functions: switching, dimming, blind, scene or room temperature control
• Value transmitter for dimming, colour temperature, RGBW, temperature or brightness values
• Transmitting the current input status after bus voltage failure
• Connection of door or window contacts for evaluation of the open, closed, tilted and handle position statuses
• Pulse counter with main and intermediate meters
• Combination of adjacent input channels when connecting push-button, door or window contact
• Connection of LED e.g. LED lamp, 5 V DC, 2.2 mA (ref-no. 9605 LED ..)
• Short-circuit proof, overload protected and protected against polarity reversal
• Parallel switching of outputs possible, for electrical loads with higher current requirements
