66121 Intra-Sewi TWIN TH-L-Pr
1. Description
The Sensor Intra-Sewi TWIN L-Pr for the TWIN building bus system captures
brightness and motion in a room. Two Intra-Sewi TWIN can be connected at the
same time to one controller.
The Sensor Intra-Sewi TWIN TH-L-Pr additionally measures the temperature and
the air humidity.
Functions:
• Brightness measurement with brightness control
• Motion detection
Additional functions Intra-Sewi TWIN TH-L-Pr:
• Measuring the temperature and air humidity (relative, absolute)
1.0.1. Scope of delivery
• Sensor
• Pre-assembled clamps for false ceiling installation
• Support ring for connector socket installation
For socket installation you will need in addition (not supplied):
• Socket Ø 60 mm, 42 mm deep

1.1.1. *Measuring accuracy
Deviations in measured values due to interfering sources (see chapter installation
location) must be corrected in the MultiController TWIN application in order to
achieve the specified accuracy of the sensor (offset).

Sensor Intra-Sewi TWIN TH-L-Pr and Intra-Sewi TWIN L-Pr
During the Temperature measurement, the self-heating of the device is taken into
consideration by the electronics. It is compensated by the software, therefore the di-
splayed/output indoor temperature measuring value is correct.
2. Installation and start-up

2.1. 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 gua-
rantee claims.
After unpacking the device, check it immediately for possible mechanical damage.
If it has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when as-
sembled and after conclusion of all installation and operational start-up tasks and
only in the surroundings designated for it.
function Technology AS is not liable for any changes in norms and standards which
may occur after publication of these operating instructions.

2.2. Installation location

Install and use only in dry interior rooms! Avoid condensation.
The Sensor is installed in a false ceiling or a standard connection socket (Ø 60 mm,
42 mm deep).
The device must be installed on the ceiling, so that the movement capturing takes
place from above. Make sure that the desired area is covered by the sensor's cover-
age angle and that no obstacles obstruct the recording.
When selecting an installation location for Intra-Sewi TWIN TH-L-Pr, please ensu-
re that the measurement results of temperature and humidity are affected as litt-
le as possible by external influences. Possible sources of interference include:
• Direct sunlight
• Draughts from windows and doors
• Draughts from ducts coming from other rooms or the outdoors
• 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 empty ducts which lead from warmer or colder areas to
the sensor
Measurement variations from such sources of interference must be corrected in the
application program for the MultiController in order to ensure the specified accuracy
of the sensor (offset).
