1-bit input object for starting and stopping valve rinsing. Valve rinsing can be activ-
ated by time or an event using this object. It is also possible, for example, to cas-
cade multiple heating actuators, so that they perform valve rinsing simultaneously
(link of the individual status objects to the input objects of the valve rinsing).
The telegram polarity can be configured. Stopping can be prevented via the object
as an option.
The time of cyclical valve rinsing is restarted as soon as an externally started valve
rinsing operation is stopped by a Stop telegram or by the expiry of the rinsing time.
Updates of the object from "Start" to "Start" or "Stop" to "Stop" do not produce a re-
action. The length of an elapsing valve rinsing operation or the cycle time of the cyc-
lical valve rinsing are not restarted by this.

1-bit output object for status feedback of a valve rinsing operation. The telegram po-
larity is fixed: "0" = Valve rinsing inactive, "1" = Valve rinsing active.
The object transmits the current status after bus and mains voltage return and after
an ETS programming operation without a delay.

Operating hours counter
The operating hours counter determines the switch-on time of a valve output. For the
operating hours counter, an output is actively on, when it is energised, i.e. when the
status LED on the front panel of the device. As a result, the operating hours counter
determines the time during which deenergised closed valves are opened or deener-
gised opened valves are closed.
The operating hours counter can either be configured as a second counter or altern-
atively as an hour counter.
–
Second counter
The actuator adds up the determined switch-on time accurately to the second
for an energised output. The totaled operating seconds are added in a 4-byte
counter and stored permanently in the device. The current meter reading can
be transmitted cyclically to the KNX by the "Operating hours counter - Meter
reading - Status" communication object or when there is a change in an inter-
val value in accordance with DPT 13.100.
–
Hour counter
The actuator adds up the determined switch-on time accurately to the minute
for an energised output in full operating hours (see figure 25). The totalled op-
erating hours are added in a 2-byte meter and stored permanently in the
device. The current meter reading can be transmitted cyclically to the KNX by
the "Operating hours counter - Meter reading - Status" communication object
or when there is a change in an interval value in accordance with DPT 7.007.
