ATTENTION
The variation of the unit of measure from ° C to ° F or vice versa,
will result in the restoration of the "default" data, or the loss of
all personal data contained and stored in the control unit, such
as thermal parameters, hydraulic diagram, meters , password
and anything else stored in the internal memory of the control
unit itself.
Restoring the default data could be exploited, for example, if the
installer wanted to reset the factory data without, however,
manipulating all the parameters individually.
If the unit of measurement is changed, the control unit will be
reset to diagram n.1 and will show on the display for about 6
seconds, the writing 'RST data', indicating that all data has been
restored to default values.
P12: MINIMUM MANIFOLD TEMPERATURE LIMITATION
The 'Minimum Temperature Limitation' parameter of the collector is
used for the management of the Minimum Thermostat relating to the
activation of the collector pumps.
This thermostat prevents the manifold pumps from being activated if
a temperature lower than that set in the parameter is detected on the
relevant panel.
The 'Minimum Temperature Limitation' function will not be active in
ABC operation or if the manifold pumps are activated due to the
Recooling function or other functions.

P14: COLLECTOR RESET TEMPERATURE
With this parameter it is possible to set the temperature value ('T_SE'
- 'T_SW') for resetting the collector pump if the TS_2 safety
temperature has intervened, in order to avoid thermal shocks and air
pockets in the system. .
The collector pump will be automatically restarted only if the collector
temperature, detected by the sensor S_1 for the EAST collector or
S_4 for the WEST collector, is lower than the reset temperature of
the collector, respectively, T_SE or T_SW.
