The THERMOCONTROL function can be activated in the following way:
1) Quickly press the
Menu Button
until the following screen appears:
After a few seconds the following screen will appear on the display:
2) Press one of the two
Scroll Buttons
and the following screen will appear (Select ON to activate).
3) Confirm the selection by pressing the
Degrees Button
and the following screen will appear:
4) Press the
Scroll Buttons
to set the activation temperature for Sensor S2. Sensor S2 is installed in the top part of the puffer
and it commands the appliance to start up as it is exhausting the available heat inside it. The setting range is between 40 °C
and 65 °C.
5) Confirm the selection by pressing the
Degrees Button
and the following screen will appear.
6) Press the
Scroll Buttons
to set the activation temperature for Sensor S1. Sensor S1 is installed in the lower part of the puffer
and it commands the appliance to shut off as the puffer is satisfied. The setting range is between 60 °C and 70 °C.
The settable temperature will in any case always exceed, by at least 4°C,the temperature setting for S2.
7) Confirm the selection by pressing the
Degrees Button
then press the
Menu Button
several times to exit the screen, until the
initial screen appears.
At this point the appliance operating status will appear on the display.
To
disable
the THERMOCONTROL function simply repeat operations 1 and 2, but this time select the OFF command. The function
will be disabled immediately.
ATTENTION
: it is advisable to set the action temperature for sensors S1 and S2 as indicated in the hydraulic diagrams
in this manual. Pay special attention to the number of ON/OFF cycles that the appliance is subjected to with this
function. It is recommended not to exceed three ON/OFF cycles. If the startups are frequent and repeated it is possible
that the the ge
nerator will fail to start and the following error message appear: “Failed start – Clean burner”. The
appearance of this message is not attributable to a product defect but is caused by a brazier that requires cleaning as
described in this manual in chapte
r entitled: “Troubleshooting – Possible Causes – Solutions”.
ATTENTION
: By setting the THERMOCONTROL ON the appliance will only start up and shut off autonomously
according to the temperature settings of sensors S1 and S2.
ATTENTION: If the programmed time schedule is enabled (a clock symbol appears on the display) the appliance will
follow exclusively the preset ON and OFF times. No request for heat from the puffer will be considered by the appliance
outside the programmed time interval and the texts WAIT TIME or NO PROGRAM will appear on the display.
ATTENTION: If an external chronothermostat is connected to the appliance, the appliance will follow it exclusively. No
request for heat from the puffer will be considered by the appliance if the external chronothermostat does not give
consent and the text WAIT TIME appears on the display.
By setting
THERMOCONTROL ON
, when the puffer is requesting heat the temperatures
detected by the sensors S1 and S2 and the word PUF will appear on the display.
When is it important to use the THERMOCONTROL function?
In systems configured like the diagram on the right, where the appliance is connected
directly to a stratification puffer.
When you use this function the generator starts up automatically when the puffer is
running out of heat then switches off when it is satisfied. The use of a correctly-sized puffer
also enables the production of low temperature heat, such as for example for under floor
heating systems, which otherwise could not be controlled by a high temperature biomass appliance.
