Features
- The room actuator controls three functions simultaneously in one
device, such as lighting, blind and heating. The four relay outputs
can be set either for blind operation or alternatively for switching
operation in the ETS (Engineering Tool Software). Mixed
operation is also possible.
- Two switching outputs make one blind output.
- In addition, there are two further electronic switching outputs for
the control of servos.
Switching operation
- The room actuator with its relay contacts controls electrical
devices such as lighting systems. The relay contacts have
flip-flop contacts, so that the last set switching condition remains
unchanged even if the power supply fails.
- Functional properties for each output: a wide spectrum of time
functions, logical links, scenes, block functions or restraints,
extended feedback, cyclical monitoring of incoming switching
telegrams and an elapsed operating time meter.
Blind operation
- The room actuator uses its relay contacts to control electrically
operated blinds, shutters, awnings, ventilation flaps,or similar
hangings with a mains voltage of AC 230 V.
- Functional properties for each output channel: separately
parameterisable movement times, extended feedback functions,
assignments of up to 5 various safety functions, a comprehensive
solar protection function and the integrating in scenes or
restraints.
Room temperature control
- Two further electronic switching outputs are used for silent
operation of electro thermic servos for heating or cooling
systems.
- Continuous correcting variable telegrams are implemented in a
pulse width modulated output signal (PWM). With this the servos
can be continuously controlled. Alternatively, implementing
switching correcting variables is also possible. Status message
for the valve position and cyclical monitoring of correcting
variable telegrams.
- Emergency mode in case of bus voltage failure or bus/mains
voltage recovery plus forced setting via bus telegram for summer
and winter mode.
- An alarm is triggered in case of short circuit or overload of the
switching output and position protection for the valves. De-
energised closed or open valve drives can be connected
- Monitoring of mains voltage supply, and in cases of malfunction,
the transmission of an alarm message on the bus.
- Group messages "all valves closed" and "largest correcting
variable".
