Inputs 
General 
E1…E5 general 
E1…E5 parameters 
Limitation of number and interval of telegrams to be send 
Labeling of inputs, selection of function as analogue-/binary-/temperature input (functions depending on input) 
Binary input: switching/alarm, dimming, blinds/shutters, value, scene, switching sequences, multiple operation, pulse counter 
Analogue input (E1 only): Voltage, upper/lower measuring limits, output value, threshhold, limits changeable via bus 
Temperature sensor input (E4/5 only): Function temperature / temperature limiter floor heater, sensor type, offset, error compensation, 
threshold 1, threshold 2
