100° × 82° (see also Coverage area of the motion detector) Range approx. 5 m The product is compliant with the provisions of the EU guidelines. Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
Elsner Elektronik 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. Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
Installation and start-up The Sensor Intra-Sewi KNX TH-Pr is installed in a false ceiling or a standard con- nection socket (Ø 60 mm, 42 mm deep). The device must be installed on the ceiling, so that the movement capturing takes place from above.
Place the device in the installation opening in the ceiling. For this, fold the clamps up- wards and guide the device through the installation opening with the clamps first. Intra-Sewi KNX TH-Pr is automatically fixed by the clamps. Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
Connect the bus line to the KNX terminal (red/black). Clamp the device in the support ring so that the springs on the device snap over the tabs of the support ring. Fig. 4: Tragring Tabs Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
The connection is made with the KNX terminal (red/black) to KNX TP. Fig. 6 Clamps for installation in false ceiling Springs for installation in sup- port ring KNX terminal Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
The movement sensor and the airing lamella must not get dirty or covered. As a rule, it is sufficient to wipe the device with a soft, dry cloth twice a year. Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.

"slave: cycle reset" in order to immediately send a message to the bus in the event of a motion detection. The master receives the motion message without having to wait for the next slave transmission cycle. Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
"Reset temperature min/max. value" objects to reset the values to the current readings. The values are not retained after a reset. Use minimum and maximum value No • Yes Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.

In the 1st level, heating is controlled by a PI control, which allows to either enter control parameters or select predetermined applications. In the 2nd level (therefore only in case of 2-level heating), heating is controlled via a PI or a 2-point-control.
