last value received through the bus even though
this value has been received during the forced
time. Via
the “Forced position” object the forced
can be enabled or disabled.
The forced function remains active even
after bus voltage failure.
The manual control via the push buttons
of the device is possible during the
forced.
VALVE PROTECTION
This function allows the valve to open automatically
for 5 minutes every 24 hours. This is a protection
measure which allows the recirculation of water
when the valve is close.
FEEDBACK FEATURE
The status of the valve can be shown via the object
“Status”. Additionally the value of the feedback
telegram can be inverted.
When the feedback telegram is enabled, the status
information is transmitted every time that a change
occurs on the output. However, it is also possible
to define a periodical sending of the status through
the parameter “Feedback Periodical Sending”.
Thereby, the current value of the output is
transmitted with the period configured.
Additionally, to reduce the bus traffic after any
failure, a delay for the status feedback transmission
at startup can be parameterized. When this option
is used, the status of the output after a bus voltage
failure is sent once the time delay configured has
elapsed.
The delay configured only affects the
sending of the feedback. The behaviour of
the outputs has no effect and they can
even be switched during the course of the
delay.
BUS VOLTAGE FAILURE
The behaviour of the output during and after bus
voltage failure can be parameterized. The combo
is equipped with bistable relays. That is why the
reaction of the output during bus voltage failure can
be configured too.
The combo actuator allows three different
behaviours for bus voltage failure:
No Reaction/Last State: The relay of the output has
no reaction and remains the last state received.
ON: The relay is closed.
OFF: The relay is opened.
The operation mode configured at
startup has priority over the behaviour of
the output after bus voltage failure.
Example:
If the parameter “Operation mode at
startup” is set as summer and the
“Behaviour After Bus Voltage Return” is
set as ON, the output will be OFF at
startup because the summer mode has
priority.
