[8] Sanitary water heating mode timer
Applies only to installations with a sanitary water tank.
The 'sanitary water heating mode timer' field settings defines the
minimum and maximum sanitary water heating times, and minimum
time between two sanitary water heating cycli.
■
[8-00] Minimum running time: specifies the minimum time
period during which sanitary water heating should be
activated, even when the target sanitary water temperature
has already been reached.
■
[8-01] Maximum running time: specifies the maximum time
period during which sanitary water heating can be activated,
even when the target sanitary water temperature has not yet
been reached.
Note that when the unit is configured to work with a room
thermostat (refer to
), 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, sanitary 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 sanitary water heating cycli.
■
[8-03] Booster heater delay time: specifies the start-up time
delay of the booster heater operation after start of the heat
pump sanitary operation.
Example
[9] Cooling and heating set points
The purpose of this field setting is to prevent the user from selecting
a wrong (i.e., too hot or too cold) leaving water temperature. Thereto
the heating temperature set point range and the cooling temperature
set point range available to the user can be configured.
■
[9-00] Heating set point upper limit: maximum leaving water
temperature for heating operation.
■
[9-01] Heating set point lower limit: minimum leaving water
temperature for heating operation.
■
[9-02] Cooling set point upper limit: maximum leaving water
temperature for cooling operation.
■
[9-03] Cooling set point lower limit: minimum leaving water
temperature for cooling operation.
[A] Quiet mode
This field setting allows to select the desired quiet mode. Two quiet
modes are available: quiet mode A and quiet mode B.
In quiet mode A, priority is given to the outdoor unit operating quietly
under all circumstances. Fan and compressor speed (and thus
performance) will be limited to a certain percentage of the speed at
normal operation. In certain cases, this might result in reduced
performance.
In quiet mode B, quiet operation might be overridden when higher
performance is required. In certain cases, this might result in less
quiet operation of the outdoor unit to meet the requested
performance.
■
[A-00] Quiet mode type: defines whether quiet mode A (0) or
quiet mode B (2) is selected.
■
[A-01] Parameter 01: do not change this setting. Leave it set
to its default value.

NOTE
■
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
sanitary water reaches its set temperature upon
sanitary mode request.

■
In case of a floor heating application, it is important to
limit the maximum leaving water temperature at
heating operation according to the specifications of
the floor heating installation.
■
In case of a floor cooling application, it is important to
limit the minimum leaving water temperature at
cooling operation to 16°C to prevent condensation on
the floor.
Do not set other values than the ones mentioned.
