System operation using continuous power


The system runs its water heating cycle once a day to fill up the storage tank unit
with heated water.

If the block out time function is selected the unit will not operate during the block out
times – this function is typically used on installations that have time of use electricity
tariffs.

The water heating cycle operation starts automatically when the residual hot water
in the tank unit is less than 40 gallons (150 litres).
 The system will not run if the electrical power supply is cut off (i.e. if it is connected
to demand response power). However, the system will automatically start operation,
once the electric power is restored.
