New possibilities for intelligent room
temperature control
The Gira KNX servo drive 3, powered by an
electric motor, controls room temperatures
for heating systems. It is suitable for use
with heaters, radiators, convectors, in
heating circuit distributors, for example, for
underfl oor heating and many other systems.
The valve drive is installed directly on a
valve connection (M30 × 1.5). The special
features of the Gira KNX servo drive 3
include an integrated room temperature
sensor, the intelligent time-switched valve
flushing and other convenient software
functions.
Precise execution of commands
The actuators in the KNX system convert
commands from presence detectors,
buttons and automatic switches into
actions. Blinds are raised and lowered,
awnings extended and retracted. Lighting
systems are controlled or the heating
is turned on and off. This enables Gira
building systems technology to deliver
intelligent and efficient resource
management.
Intelligent evaluation of environmental
influences
The Gira KNX system offers various
products which analyse and evaluate data
from the surroundings including brightness,
temperature, and weather data, and then
forward it to various actuators. These then
control e.g. lighting, heating, blinds and
awnings, but also motorised windows.
Controlling electrothermic valve drives
The Gira KNX heating actuator, 6-gang,
controls heating or cooling cycles. It
operates electrothermic actuators on
radiators or underfloor heating manifolds
to control the hot-water flow. Up to four
servo drives AC 230 V or up to two servo
drives AC 24 V can be controlled per
channel. The actuator is suitable for private
homes as well as for commercial
properties.
VDE-tested safety
Nearly all Gira KNX products suitable
for 230 V mains voltage are also tested for
electric safety in accordance with VDE –
which can be recognised by the VDE logo,
e.g. on the device label.
KNX system devices form the base of the
system, and allow it to be greatly
expanded
Interfaces, IP routers, KNX area/line
couplers, line amplifiers, the logic module
or components for power supply are
amongst the Gira KNX system devices.
They serve the purpose of establishing a
KNX communication structure and power
supply for KNX system. Gateways from
the Gira KNX range also enable intelligent
control and operation of all systems.
Intelligent and functional products for more possibilities
As a systems provider, Gira makes available numerous components for building a
powerful KNX system. The Gira product range includes a broad spectrum of different
sensors, actuators and system devices. This makes it possible to create intelligent
building systems technology that is always state of the art.
