Domestic Hot Water (DHW)/Legionella Prevention
The domestic hot water and legionella prevention menus control the operation of
DHW tank heat ups.
<Eco mode>
DHW mode can run in either 'Normal' or 'Eco' mode. Normal mode will heat the
water in the DHW tank more quickly using the full power of the heat pump. Eco
mode takes a little longer to heat the water in the DHW tank but the energy used
is reduced. This is because heat pump operation is restricted using signals from
the FTC based on measured DHW tank temperature.
Note: The actual energy saved in Eco mode will vary according to outdoor
ambient temperature.
Return to the DHW/legionella prevention menu.
Forced DHW
The forced DHW function is used to force the system to operate in DHW mode. In
normal operation the water in the DHW tank will be heated either to the set tem-
perature or for the maximum DHW time, whichever occurs first. However should
there be a high demand for hot water 'Forced DHW' function can be used to pre-
vent the system from routinely switching to space heating/cooling and continue to
provide DHW tank heating.
Forced DHW operation is activated by pressing button F1 and Back button in the
'Option Screen'. After DHW operation finishes, the system will automatically re-
turn to normal operation. To cancel forced DHW operation hold down button F1 in
the 'Option Screen'.
