Hitaliði 1f. KNX
Features:
- Heating actuator with three binary inputs for controlling thermal servos.
- Output, can be controlled via a corrected variable (1-bit or 1-byte).
- Status feedback (1-bit or 1-byte) automatically or on read request.
- Valve control (open/closed while de-energized) can be configured.
- Summer or winter operation can be selected via an object.
- Cyclical monitoring of the corrected variable; if a corrected variable
telegram remains off within a monitoring period, the output switches into
emergency mode and an alarm message is sent.
- Each output can be locked in a forced position, and different values are
possible for summer and winter operation.
- Behaviour upon bus voltage recovery and fails can be parameterised
separately for each output.
- Messages to indicate short circuits or load failures can be set via an
object.
- Control of valve drives in switching operation or PWM operation.
- Protective function against jammed valve.
