KNX multistation controller

Description

Intended use

• Switching of electrical loads with floating contacts
• Switching of electrically-driven blinds, shutters, awnings and similar hangings
• Switching of electrothermal drives
• Polling of conventional switching or push-button contacts, window contacts etc. in KNX systems, for reporting of states, meter levels, operation of loads, etc.
• Polling of external temperature sensors for heating control
• Logic functions to control building functions
• Mounting on DIN rail according to EN 60715 in distribution boxes

Product characteristics

• Actuator functions: switching, blinds, electrothermal drives
• Actuator function can be switched in pairs

• Central switching function with collective feedback
• Time functions: switch-on delay, switch-off delay, staircase lighting timer with pre-warning function

Blinds function

• Max. 3 blinds outputs
• Suitable for 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: 3 independent wind alarms, rain alarm, frost alarm
• Sun protection function

Function of valve drives

• Max. 2 outputs for electrothermal drives
• Switching operation or PWM operation
• Actuators with characteristics opened or closed without power controllable
• Emergency operation in case of bus voltage failure for summer and winter
• Protection against jamming valves
• Forced position
• Cyclical monitoring of the input signals can be parameterised

Heating controller

• 2 internal controllers to control two independent rooms
• Control for heating or cooling, optionally with additional level
• On-off, PWM or PI control
• Predefined heating types (hot water heating, fan coil unit ...) or individual parameters possible

Inputs

• 6 inputs for push-buttons
• Input functions: switching, dimming, blinds control, light scene extension unit, brightness or temperature value transmitter
• 2 inputs for external temperature sensors

Logic functions

• Up to 10 logic operations with up to 8 inputs each, e.g. for AND, OR and XOR operations
• Conversion of data point types, e.g. from 1-bit to 8-bit
• Comparative operations, e.g. <, >, _, _
• Arithmetic functions, e.g. +, _, *, :
