INSTALLATION AND INITIAL CONFIGURATION
The device can be installed on the wall or to cover the 3-module flush-mounting box (type 503).
We recommend positioning at a height of 1.5 meters from the floor, in an area that respects as
much as possible the average temperature conditions of the entire environment. Make sure that the
distance between the router and the device is such as to guarantee stable communication.
Avoid installation near doors or windows, in niches, behind doors and curtains or in positions with
excess or total lack of ventilation, to avoid that the reading of the temperature measured by the probe
is in some way offset.
