NOTICE
The default values mentioned in "Field settings table" on
page 15 are the values from factory. The actual initial
values shall be selected according to your application.
These values shall be confirmed by your installer.
The unit shall be configured by the installer to match the installation
environment (insulation of the house, etc.) and user demand.
However, the field settings [0] and [1] mentioned in "Field settings
table" on page 15 can be modified to customer preferences. Thereto,
a number of so called field settings are available. These field settings
are accessible and programmable through the user interface on the
indoor unit.
Each field setting is assigned a 3-digit number or code, for example
[1-03], which is indicated on the user interface display. The first digit
[1] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.
A list of all field settings and default values is given under "Field
settings table" on page 15. In this same list, we provided for 2
columns to register the date and value of altered field settings at
variance with the default value.
A detailed description of field settings [0] and [1] are given under
"Detailed description" on page 13, the other field settings are
exclusively described in the installation manual.

Detailed description
To understand the field setting possibilities explained in the following
chapters, understand that different domestic hot water tank operation
modes are possible.
■
Powerfull operation
■ If the P button is pressed, the heat pump module heats up
the domestic hot water tank as fast as possible to a
predefined setpoint.
compressor frequency will be higher then in normal operation
mode and that sound level and power consumption can be
higher.
This mode might be usefull when exceptional high hot water
consumption depletes all the available domestic hot water
and hot water is required.
■ Depending on settings, simultaneous heat pump operation
and booster heater operation can occur (refer to the
installation manual).
INFORMATION
The unit increases the domestic hot water temperature by
using the indoor stored heat.
NOTICE
The powerful mode might not function properly when the
room ambient temperature is too low.

temperature. This can be required for e.g. legionella
prevention.
■ This mode is enabled by default.
■
Reheat operation
This mode will prevent the domestic hot water from cooling down
lower than a certain temperature. When enabled the unit will
heat up the domestic hot water tank when the reheat minimum
value is reached. This heating will continue until the reheat
maximum temperature is reached.
This means that the unit can heat up continuously and e.g. not
limited to night time operation. The difference with continuous
operation mode is that in reheat operation mode the domestic
water tank is heated up to a lower set point than the standard
scheduled set point. This function is only valid when schedule
timers are used.
