4on one face of the area to be heated, on the north if possible
4half way up the wall in the room to be heated
4under the influence of meteorological variations
4protected from direct sunlight
4easy to access
ARecommended position
BPossible position
HInhabited height controlled by the sensor
ZInhabited area controlled by the sensor
Positions to be avoided:
4masked by a building element (balcony, roof, etc.)
4close to a disruptive heat source (sun, chimney, ventilation grid,
etc.)
4.2.2. Connecting the outside sensor
Mount the sensor using the screws and dowels provided.

4.4.5. Hot water storage tank connection
nQUADRO DU storage tank
In this installation example, the storage tank (type QUADRO DU)
incorporates a domestic hot water zone. The boiler starts up
systematically to maintain the domestic hot water zone in the storage
tank or to maintain the independent tank at temperature.
If the storage tank does not have a DHW zone, use an
independent domestic hot water tank.

The DHW part is maintained at the DHW set point by the
boiler.
The heating zone is maintained at the set temperature
calculated according to the outside temperature. The zone
is reheated when the heating buffer temperature sensor
E falls -6°C below the calculated set temperature.
Reheating in the heating zone stops when the heating
buffer temperature rises above the calculated set
temperature.
