Installation
3.1. Installation location and preparation
The
Nunio KNX M-T push button
is installed on a socket. For correct temperature
recording, a wind-tight socket must be used. The casing of the device must not be
opened.
May be installed and operated in dry interior rooms only.
When selecting an installation location, ensure that the measurement results are af-
fected as little as possible by external influences. Possible sources of interference in-
clude:
•
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
•
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
Measurement variations from permanent sources of interference can be corrected in
the ETS in order to ensure the specified accuracy of the sensor (offset).
3.2. Connection
DANGER!
Danger due to electrical voltage
(mains voltage)!
•
The socket, in which the device is installed, must not contain cabling
with 230 V.
•
Observe the regulations and standards applicable to SELV circuits
during installation and wiring of the KNX connection and inputs.
First install the windproof socket with feed line. Seal the inlet tubes as well, in order to
prevent draughts.
Then screw the base frame to the box.
Connect the
KNX databus
+/- to the KNX connection terminal (black-red).
Insert the device firmly onto the metal frame using the fixing clamps so that the device
is fixed.
