Technical specifications and installation instructions
Item number 20559
1.
Description
The
Indoor Sensor WG AQS/TH gl
transfers temperature, humidity and CO
2
con-
tent of the air to the control system via radio. Several separate
WG AQS/TH gl
can
be taught to one control system. The teaching is described in the chapter “Learn wi-
reless connections” (manual of the control system).
The
WG AQS/TH gl
consists of the housing, the base plate and a frame. As an al-
ternative to the supplied frame, a frame of the switch series used in the building may
be used. You will additionally require a junction box according to DIN 49073 (not in-
cluded in scope of delivery).
For power supply (11…28 V DC), e. g. 12 V DC can be tapped from the connection
board of the control unit (multifunctional input).
Functions:
•
Measurement of
temperature
,
air humidity
(relative) and
CO

content of
the air
•
Suitable for: WS1 Color/Style, (KNX) WS1000 Color/Style/Connect, Solexa II
(Temperature evaluation only)

1.2. Technical specifications
The product conforms with the provisions of EU guidelines.
1.2.1. Measurement accuracy
Deviations in measured values due to interfering sources (see chapter
installation
site
) must be corrected in the controller menu in order to achieve the specified sen-
sor accuracy.
To ensure a correct
CO
2
measurement
, the device must be installed in a windproof
socket. After applying the operating voltage, it can take up to 15 minutes until the
CO
2
measured value
is output correctly.
The
measured temperature and humidity values
can be corrected in the cont-
roller menu. This may be necessary if the values at the sensor do not correspond to
the room average (for example, if the sensor is positioned in a location which is war-
mer than average). Please be aware that usable measured values can only be achie-
ved approx. two hours after putting the sensor into operation (warm-up phase).

Installation and commissioning
Installation, testing, operational start-up and troubleshooting should
only be performed by an authorised electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• Inspect the device for damage before installation. Only put undamaged
devices into operation.
• Comply with the locally applicable directives, regulations and provisions for
electrical installation.
• Immediately take the device or system out of service and secure it against
unintentional switch-on if risk-free operation is no longer guaranteed.
Use the device exclusively for building automation and observe the operating inst-
ructions. Improper use, modifications to the device or failure to observe the opera-
ting instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition
and after conclusion of all installation and operational start-up tasks, and only in the
surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may
occur after publication of these operating instructions.
2.1. Installation position
The
Indoor Sensor WG AQS/TH gl
is installed on a device socket.
May be installed and operated in dry interior rooms only.
Avoid condensation.
When selecting an installation location, please ensure that the measurement results
are affected as little as possible by external influences. Possible sources of interfe-
rence include:
•
Direct sunlight
•
Drafts from windows and doors
•
Draft from ducts which lead from other rooms or from the outside to the
junction box in which the sensor is mounted
•
Waste heat from the control unit (when mounted above the display)
•
Warming or cooling of the building structure on which the sensor is mounted,
e.g. due to sunlight, heating or cold water pipes
•
Connection lines and ducts which lead from warmer or colder areas to the
sensor
Temperature deviations caused by such sources of interference must be corrected
in the control system menu, in order to achieve the specified sensor accuracy (see
manual chapter
Wireless connections > Status
).
For a correct CO
2
measurement it is necessary to install the device in a windproof
junction box.
