12.5 HEATING MODES
The heat pump controller offers five smart modes, allowing customisation for any home’s
specific requirements. EACH MODE HAS UNIQUE:
SET TEMPERATURE
(Water temperature at end of heating cycle)
TRIGGER TEMPERATURE (Water temperature that starts a new heating cycle)
HEATPUMP TEMPERATURE (Water temperature heated to by heat pump during cycle)
ELEMENT TEMPERATURE (Water temperature heated to by element during cycle)
ENERGY (kW used for one heat cycle from 15°C Start to mode SET TEMP @ 15°C wet bulb temperature)
SET TRIGGER HEATPUMP ELEMENT ENERGY
ECO
(Default Setting)
60°C 48°C 60°C NONE 3.2.50kW
The heat pump is solely responsible for heating and does not rely on the element for
any input. This mode of operation is highly recommended for households with Small or
Medium demand, who do not wish to set timers or have the system run on a controlled
tariff.
STANDARD
60°C 55°C 60°C NONE 2.50kW
To maximise the usage of your home solar PV or take advantage of specific time-of-use
tariff periods, it can be beneficial to switch your system to STANDARD mode instead of
the default ECO mode. This is because STANDARD mode lowers the trigger temperature
from 48°C to 55°C. This reduces the impact of tank stratification, making it more likely for
the system to engage a heat cycle in the appropriate timer window. By doing so, you can
optimise the usage of your system and save money on your energy bills.
HYBRID
65°C 55°C 60°C 65°C 3.38kW
This mode is ideal for households falling under the Small or Medium load profile, and who
want to limit the heating system to a once-per-day cycle to make the most of Solar PV
output or to synchronise with off-peak time of use tariffs. The higher temperature setting
helps meet hot water demands when recovery windows are limited by timers. Although it
consumes an additional 0.9kW, the cost of using solar or off-peak power is much lower
compared to peak power, which makes up for the additional consumption cost.
HYBRID+
70°C 50°C 60°C 70°C 4.30kW
Recommended for homes with medium to large usage that want to limit their heating to a
once-per-day heating cycle. This is to take advantage of solar PV output or off-peak time-
of-use tariffs. The higher set temperature helps meet demand when timers limit recovery
windows. Although this mode consumes an additional 1.8kW of energy per cycle, it can
be cost-effective compared to running other less energy intensive modes on a continous
power tariff.
ELEMENT
70°C 60°C NONE 70°C 9.99kW
This mode is as a temporary solution for the hot water supply in case an onsite service is
needed. It can also be helpful for homes whose heat pump has reached the end of its life
to provide hot water while considering replacement options. This can alleviate the time
pressure often associated with hot water replacements and prevent decisions that could
negatively affect the consumer.
