7.1.7 System shows P or E code on controller.
If the controller on your system is presenting with a 'P' or 'E'
code followed by a number, then this is highlighting an error or
protection function within the system.
Please refer to the following table (over page) for further details
or contact our service team for further assistance.
7.1.8 The compressor is not starting immediately after
the setting has been changed
The unit has a self protect logic that will wait for 3 minutes
before starting the compressor to ensure the pressure of system
is balanced
7.1.9 The temperature shown on the display panel
sometimes decreased while unit is running
When additional cold water is introduced to the tank (as hot
water is drawn off) the heated water will mix with the cold water
and reduce the overall temperature.
7.1.10 Temperature shown on the display is
decreasing but the unit is not turning on.
To avoid the unit continually switching ON & OFF frequently,
the unit will only activate the heat source when the bottom of
the tank temperature is lower than setting temperature by a
minimum of 5ºC.
7.1.11 The temperature shown on the display
sometimes decreases dramatically
This generally occurs when there is a massive demand for
hot water and so a large amount of cold water flows to the
upper temperature sensor causing the display to decrease
dramatically.
