Parameter setting
KNX K8 actuator
• Status: 18.11.13 • Technical Changes and Errors excepted.
Determine when the general channel status (e.g. ON, OFF, percentage) is to be sent.
The channel may be blocked by a
blocking object
(e. g. block during ventilation). The
output value during the block can be set.
The
channel LED
shows when the output channel is ON. When the channel is
switched on in automatic mode, the LED is on. When the channel is switched on in
manual mode, the LED flashes.
LED light or flashing may be switched off after a certain period to save energy.
4.4.
Temperature controller
The
KNX K8 actuator
provides eight temperature controls that are independent of
the device outputs and thus may also be used for the control of other heating/cooling
actuators.
4.4.1. General regulation
For an adequate regulation of the indoor temperature, comfort, standby, eco and
building protection modes may be used.
Comfort
when present,
Standby
during short absences,
Eco
as a night-time mode and
Frost/heat protection
(building protection) during longer absences.
The settings for the temperature control include the set point temperatures for the
individual modes. Objects are used to determine which mode is to be selected. A
change of mode may be triggered manually or automatically (e.g. by a timer, window
contact).
