With
1 byte (continuous)
selected, an additional parameter appears:
Transmit status response Object "Status heating"
Options:
no
yes, 0% = "0" otherwise "1" (1 bit)
yes, 0% = "1" otherwise "0" (1 bit)
yes, continuous control value (1 byte)
This parameter is only visible with continuous control with a 1 byte value.
For 2-step control the current control value is synonymous with communication object
Status
Switch
.
•
no
: A control value is not reported back.
•
yes, 0% = "0"
otherwise "1" (1 bit)
and
0% = "1" otherwise "0" (1 bit):
enables communication
object
Status heating (1 bit).
The current control value is sent.
•
yes, continuous control value (1 byte):
enables communication object
Status heating (1 byte
).
The current control value is sent.
PWM-cycle time for continuous control
Minutes [3…65,535]
Options:
3...10…65,535
PWM-cycle time for continuous control
Seconds [0...59]
Options:
0...59
With 1 bit control this time setting is only used during control of the actuator in fault mode, with the Forced
operation function and directly after bus voltage recovery.
With 1 byte control (continuous control), this setting determines the duration of the control signals. This
corresponds with the cycle time t
CYC
.
The time has been limited to three minutes to suit the endurance of the switch relay, as the number of
relay switching operations is limited.

Position of the valve drive on
bus voltage recovery
Options
0% (closed)
10% (26)
...
90% (230)
100% (open)
This parameter sets how the valve drive is set after bus voltage recovery until the first switching or
positioning telegram is received from the room thermostat. The Switch Actuator uses PWM control with the
parameterized PWM cycle time until the room thermostat sends a signal.
The value in brackets corresponds to the 1 byte value.
