3. ADJUST DATE & TIME.
Using the touch screen, press on the value and
change it accordingly. Note that the time is
displayed in a 24-hour format.
The heat pump will keep the time if the system has no power, using the in-built
battery. However, if the system is not powered for a long period of time the clock
may not be set correctly when the system has been turned on again.

12.4 SETTING HEATING TIMER WINDOWS
USING THE IN-BUILT TIMERS IS RECOMMENDED FOR THE FOLLOWING REASONS:
1. The in-built timers can be used to fully utilize a Solar PV system
2.
temperatures are at their highest.
3. Running the heat pump during the day will minmise noise disturbance.
THE FACTORS TO CONSIDER WHEN USING TIMERS ARE:
1. TARIFFS - Certain tariffs will not coincide with the default timer periods and therefore the
system may not have enough time to recover.
2. HOT WATER USAGE - Be aware of your peak usage and recovery times.
3. TEMPERATURE & CLIMATES - Ensure you allow enough time for the unit to heat in varying
temperatures and humidity.
4. MULTIPLE HEATING WINDOWS – If setting multiple heating windows each window should
be a minmum 3 HOURS. Setting shorter windows will impact performance and longterm
durability.
5. LEGIONELLA CONTROLL – The system should have a minimum daily time to heat of at
least 6 HOURS. This should ensure that a minimum 45% of stored water will reach a
temperature of 60°C daily.
6. TRIGGER TEMPERATURES – If the system fails to reach the set temperature during a
heating window, it will not begin reheating untill the tank water temperature reaches the
trigger point based on the selected mode.

We recommend running the single timer window (08:00 – 18:00) which comes pre-
set as a factory default and only needs to be turned on with adjustment. This period
is typically the hottest part of the day and when energy produced from Solar PV is
at its highest.
