Pump anti cavitation mode:
This feature sends two electric pulses every 5minutes to the pump. This
prevents the build up of air bubbles inside the pump and ensures an even
flow of hot water at the tap.
Power Pulsing mode:
This is a default set point control feature which ensures the hot water is
maintained as close as possible to the set point. This is achieved by applying
a closer tolerance to the set point temperature range. It is estimated that 1 in
15,000 installations could experience intermittent flickering lights, during the
boiling water recovery period. Disabling may overcome the flickering lights,
however, the unit may experience increased steaming.
Fan speed adjustment:
If the undersink unit is operating near 35°C then the fan speed must be
100%. The fan speed may be adjusted for quieter operation only if the
operating temperatures are considerably lower than 35°C.
