5.4 Installing the system interface<br />
Note: when installing cascade systems, to install the system<br />
interface refer to the relevant dedicated manual.<br />
Positioning<br />
The system interface detects the room temperature. This factor<br />
must be taken into account when choosing its position.<br />
We recommend positioning the appliance far from heat sources<br />
(radiators, direct exposure to sunlight, fireplaces, etc.). We<br />
also advise against positioning it near draughts or external<br />
openings that could affect the operation of the system interface.<br />
The interface must be placed at least 1.5 m above the floor.<br />
a<br />
<strong>Installation</strong> should be performed by a qualified<br />
technician. Before installing the appliance, ensure<br />
that the electrical power supply is disconnected.<br />
