[1] Normal operation: the tank will cool more slowly for the same DHW performance if the DCW is above normal DCW temperature, thus saving fuel.
[2] Solar tank hot: therefore the burner will not be required at high DHW flow rate and the tank will boost the solar heated water if the temperature
drops.
[3] Solar tank will satisfy the DHW requirements: therefore the appliance allows the water to pass straight through without taking any action apart
from monitoring the temperatures. To utilise the solar panels to their maximum potential, the solar tank thermostat will need to be set high and
the Heatslave II DHW setting low.
[4] Solar tank overheat: DCW above solar tank limit, appliance will not operate pump or burner and fault code will be displayed within the service
menu.
