8.3.2 Mode selection:
The unit has seven modes: Standby, Heating, Eco Heating, Intelligent , Electric Heater, Fan and Vacation.
a) Standby Mode: The unit has power on to it but it is not set to heat.
b) Heating Mode: The water will be heated by ASHP. If the target temperature is not achieved by a
pre-programmed time (200 minutes), the immersion heater is switched on to accelerate the time taken
to reach the target temperature.
c) Eco Heating Mode: The water will be heated by ASHP only. This is normally used where the input
air temperature is higher.
d) Intelligent Mode: In this mode, the unit will heat the water by ASHP alone unless the input
temperature is too low, in which case the electrical heater is switched on.
e) Electric Heater Mode: Water is heated by immersion heater. This should only be used in the
unusual circumstance when the input temperature is very low.
