• Can be updated with the ETS Service App

 
Fan coil function

• Connection of up to two fan coils with fan levels or permanently controlled fans
• Operating modes for heating, cooling or combined heating/cooling operations
• 2-pipe or 4-pipe operation
• Individual or hierarchical switching of the fan levels or permanent control of the fan

• 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

 
Blinds function

• 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

 
Function of valve drives

• Switching operation or PWM operation
• Continuous control of valve drives with 0-10 V interface
• Valve drives with characteristics "normally open" or "normally closed" can be controlled

 
HVAC function

• 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

 
Dimming function

• 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
• 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

 
Analogue outputs 0-10 V

• Connection of 0-10 V control cable of valves or fan motors
• Connection of 0-10 V control cable of thermal valve drives
• Short-circuit proof

 
Satellite units

• 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
• Connection of motion detector mini basic (ref.-no.: BM 360 MB WW), condensation (ref.-no.: BTS 01), leakage sensors (ref.-no.: LES 01) and external temperature sensor (ref.-no.: FF NTC)
• 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 ..)
