2 Description
Indoor Sensor WGTH-UP • Version: 13.12.2016 • Technical changes and errors excepted.
1. Description
The WGTH-UP Indoor Sensor transfers temperature and humidity to the control sys-
tem via radio. Several separate WGTH-UP can be taught to one control system. The
teaching is described in the chapter “Learn wireless connections” (manual of the con-
trol system).
The WGTH-UP Indoor Sensor consists of the housing, the sensor PCB/base plate and a
frame. As an alternative to the supplied frame, a frame of the switch series used in the
building may be used. You will additionally require a junction box (Ø 60 mm, 42 mm
deep, not included in scope of delivery).
For power supply (7...30 V DC), e. g. 12 V DC can be tapped from the connection board
of the control unit (multifunctional input).
2. Installation of the indoor sensor
2.1. Installation location
The interior sensor is to be installed flush to the wall surface in a junction box (Ø 60
mm, 42 mm deep). The ideal installation hight is approx. 1.40 m above the ground.
When selecting an installation location, please ensure that the measurement results
are affected as little as possible by external influences. Possible sources of interference
include:
• Direct sunlight
• Drafts from windows and doors
• Draft from ducts which lead from other rooms 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 which lead from warmer or colder areas to the sensor
Temperature variations from such sources of interference must be corrected in the
control unit menu in order to ensure the specified accuracy of the sensor (see manual
chapter on Wireless connections > Status).
The indoor sensor must only be installed and used in dry, interi-
or spaces. Avoid condensation.

2.3. Rear view
2.4. Installation
First install the junction box. Seal the inlet tubes in order to prevent drafts.
Connect the power supply +/- to the connector terminals provided for this purpose on
the sensor board. Then screw the board/base plate onto the socket. Ensure that the
front side with the writing „TOP“ is directing out of the wall and that the arrows point
towards the top.
Position the frame of the switching programme. Insert the housing of the sensor firmly
onto the base plate using the catches, so that the housing and frame are fixed together.

4 Notes on mounting and commissioning
Indoor Sensor WGTH-UP • Version: 13.12.2016 • Technical changes and errors excepted.
3. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative humidity of 95%. Avoid condensation.
4. Establish radio connection with WGTH-UP
1. Bring the control unit into learning readiness mode (note chapter Learn wireless
connection in the manual).
2. Press the programming button at the WGTH-UP sensor
3. Pay attention to the report of the control unit (“Device successfully learnt”).
5. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• National legal regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for its intended purpose. Any improper modification or
failure to follow the operating instructions voids any and all warranty and guarantee
claims.
After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.
The programming button is situated behind the
right lower opening of the housing.
Use e. g. a paper-clip or a wire to press the but-
ton.
