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 generator 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 manua
l in chapter 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 (see
dedicated paragraph).
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 (see para. 6.10).
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.
6.7 ACS SUMMER: ACTIVATION OF THE BOILER TUBE CONTROL FROM A CHRONO COMMAND
The appliance must be energised and the I/0 switch in position
“I".
This function enables you to manage the operating temperature of a boiler tube for the production of domestic hot water (ACS)
through the use of a sensor PT 100 (optional) connected to the terminal block on the electronic board.
ATTENTION: If the optional sensor is not connected to the appliance or is interrupted, it will not be possible to view and therefore
activate this function.
When this function is activated the appliance automatically controls the ON/OFF cycles based on the set temperature of the boiler
tube, and ignores requests for heat from the system and the puffer, if installed. This function is particularly useful in summer when
only domestic hot water is required without having to supply the heating system.
When this function is activated the appliance operates only at automatic power.
The ACS SUMMER 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 appears:
