• Valve drives with characteristics "normally open" or "normally closed" can be controlled
• 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
• 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
• 6 inputs for push-buttons
• Function of the inputs: switching, dimming, shutter control, light scene extension, brightness or temperature value transmitter
• 2 inputs for external temperature sensors
• 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. +, –, *, :
