Ambient chronothermostat with integrated temperature probe.
The image - to be considered just as an example- represents the warm air heater installed in a room other
than the one to be heated but, if possible, it can be installed in the room itself.
The operating principle is described below:
•
When the chronothermostat with integrated temperature probe (
C
) positioned in the room detects a
temperature lower than the value set, it commands burner ignition (
B
)
.
•
Approx. 1 minute after the flame has been ignited, also the ventilation unit starts, thus releasing warm air
in the room.
•
The temperature probe integrated within the chronothermostat (
C
) connected to the burner thermal power
regulation system (
A
) will automatically change it according to the user's immediate needs. The burner will
operate at maximum heat output when the temperature is very low with respect to the value set, and then
progressively decreases if the temperature increases.
•
If the ambient chronothermostat detects that the temperature set has been reached, it gives the consent
to switch off the burner. After approx. 3-
4 min’
- when the heat exchanger has completely cooled- the
ventilation unit goes off, too.
With a decrease in the burner thermal power (at constant air flow), there is a reduction
in the temperature of the fumes, which can also lead to their condensation. In this case
the condensation produced is discharged to the outside through the appropriate
connection.
The previous drawing shows the example of positioning of the chronothermostat with integrated probe:
Example no. 4
:
In this case the temperature probe is integrated into the chronothermostat and is
positioned directly in the environment to be treated;
it represents the best solution for
direct control of the room to be heated.
