WORKING WITH THE CONTROLLER
General information
The controller is managed by easy and intuitive software specifically designed to automate boiler
management.
When the water heater is switched on, he selects by itself the most suitable heat source. Priority is
given to using the solar collector (NHPC-V4-2 only) and the heat pump. The electric heater will only
be used if the heat pump is deactivated or if the set temperature is above the heating capabilities of
the heat pump. It will also be switched on if "
Enhanced Heating
" mode is used.
If the differential temperature associated with the solar collector
Dt1 = t3 - t1
is greater than the
threshold set in the “
Pump
Control”
menu, item "
Solar Dt1
", column "
On
", the solar collector
circulation pump will be switched on in order to transfer its heat to the water heater. When the solar
pump is switched on but the differential temperature Dt1 drops below the threshold set on the same
row in the "
Off
" column, the pump will shut off.
