DHW cylinder reheat times
1. The appliance is factory set so that only the engine burner is
used to reheat the DHW cylinder. This is in order to maximise
electricity generation. If this results in unsatisfactorily long reheat
times then the supplementary burner can be used to reheat the
cylinder as well and this will reduce the reheat times to roughly a
third of those with engine burner only.
To switch the supplementary burner on for DHW heating: -
a) From the main screen press the menu button, scroll down to
‘temps/mode hot water’.
b) Press the Selector Button to select and scroll down to ‘Release
HW charging’.
c) ‘Eng bu only’ will appear
d) Press the Selector Button to change, ‘Eng bu only’ will flash,
scroll to change to ‘No restrictions’ and press the Button to
select. This will allow the supplementary burner to light during
DHW demands.
e) ‘Eng bu only’ may be reselected at any time.
