[8] Domestic water heating mode timer
Applies only to installations with a domestic hot water tank.
The 'domestic water heating mode timer' field settings defines the
minimum and maximum domestic water heating times, and minimum
time between two domestic water heating cycli.
[8-00] Minimum running time: specifies the minimum time
period during which domestic water heating should be
activated, even when the target domestic water temperature
has already been reached.
[8-01] Maximum running time: specifies the maximum time
period during which domestic water heating can be activated,
even when the target domestic hot water temperature has
not yet been reached.
Note that when the unit is configured to work with a room
thermostat
(refer
to
"Room
configuration" on page 19), the maximum running timer will
only be taken into account when there is a request for space
cooling or space heating. When there is no request for room
cooling or room heating, domestic water heating by the heat
pump will continue until the 'heat pump OFF temperature'
(see field settings [5]) is reached. When no room thermostat
is installed, the timer is always taken into account.
[8-02] Anti-recycling time: specifies the minimum required
interval between two domestic water heating cycli.

Time
Take care that [8-03] is always smaller than the
maximum running time [8-01].
By adapting the booster heater delay time versus
the maximum running time, an optional balance
can be found between the energy efficiency and
the heat up time.
However, if the booster heater delay time is set
too high, it might take a long time before the
domestic hot water reaches its set temperature
upon domestic hot water mode request.
