Heater capacity
Initial setting: Yes
Operate anti-freezing of water circulation circuit.
If select Yes, when the water temperature is reaching its freezing temperature, the
circulation pump will start up. If the water temperature does not reach the pump
stop temperature, back-up heater will be activated.
If set No, when the water temperature is reaching its freezing temperature or
below 0°C, the water circulation circuit may freeze and cause malfunction.
Anti freezing
Initial setting: Variable
Variable DHW capacity setting normally run with ef
fi
cient boiling which is energy
saving heating. But while hot water usage high and tank water temperature low,
variable DHW mode will run with fast heat up which heat up the tank with high
heating capacity.
If standard DHW capacity setting is selected, heat pump run with heating rated
capacity at tank heat up operation.
