DHW thermostat
Establishes the boiler ignition and switch-off mode in DHW mode.
0 - Ignition occurs when the water contained in the storage tank drops by 3 °C
with respect to the temperature set and switches off when the temperature
is at the value set (solar deactivated)
1 - Ignition occurs when the water contained in the storage tank drops by 2 °C
with respect to the temperature set and switches off when the temperature
is at
+
1 °C with respect to the value set (solar deactivated)
2 - Ignition occurs when the water contained in the storage tank drops by
10 °C with respect to the temperature set and switches off when the
temperature is at the value set (Solar activated)
3 - Ignition occurs when the water contained in the storage tank drops by 5 °C
with respect to the temperature set and switches off when the temperature
is at the value set (Solar activated)
