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 means the same as the
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)
The communication object Status heating (1 bit) is enabled. The
current control value is sent.
• continuous control value (1 byte): The communication object
Status heating (1 byte)
is enabled. 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
For 1 bit control, this time setting is only used during control of the actuator
in fault mode, with the function Forced operation and directly after bus
voltage recovery.
With a 1 byte control (continuous control), the periodic duration of the control
signals are set with this setting. This corresponds with the cycle time t
CYC
.
The time has been limited to 3 minutes in order to suit the endurance of the
switch relay, as the number of relay switching operations is limited.
For further information see:
, page 156 and
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 parameterised
PWM cycle time until a signal is sent from the room thermostat.
The values in brackets correspond to a 1 byte value.
