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).

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.
Indoor Sensor WGTH-UP • Version: 13.12.2016 • Technical changes and errors excepted.
