2 Location of the temperature sensors
2.1 Room air sensor
Install the sensor at a height of about 1.5 m in a representa-
tive location in the occupied area. Its measured values must
not be distorted by the presence of sources of heat or cold
(machines, direct sunlight, windows, doors, etc.).
Normally, you should use one room air sensor for each
control zone. It is also possible to install four sensors to
determine the average temperature value.
2.2 Fresh air sensor
Install the sensor at least 3 m above the ground on a
north-facing wall, so that it is protected from direct sunlight.
Provide additional cover for the sensor and thermally insulate
it from the building.
Only one fresh air sensor is needed per system.
Extract air and supply air sensors are installed in the
RoofVent
®
units.
3 Orientation of the coil connections
The heating or cooling section is usually fitted to the filter box
in such a way that the coil connections are underneath the
extract air grille (see Fig. M5). Check the local installation
conditions. If a different orientation is required, please specify
on the purchase order.
