Boost Mode
If it is required to boost the hot water temperature at any time using the electric water element,
this can be done by simply pressing the boost button.
Boost can also be used to manually turn on an output when operating in threshold mode.
When boost mode is activated the output will be turned on irrespective of whether there is any
surplus PV power available.
Pressing the boost button will turn on the boost for output 1.
A second press of the boost button
within 2 seconds
will turn on the boost for output 2.
The system function display will then change to show “Boost 1 ON” or “Boost 2 ON” and the
remaining time boost will be active. The first press of the boost button will give a 1 hour boost
time. Each subsequent press of the button while boost is on will add 1 hour to the boost time up
to a maximum of 4 hours.
A further press of the boost button when boost is already set for 4 hours will turn off boost
mode.
Boost mode will automatically turn off when the pre-set temperature is reached or the boost
time reaches zero.
