[9-05~9-08] Automatic setback function
Setback function provides the possibility to lower the water
temperature during space heating. The setback function can for
instance be activated during the night because the temperature
demands during night and day are not the same.
■
[9-05] Status: defines whether the setback function is turned
ON (1) or OFF (0)
■
[9-06] Start time: time at which setback is started
■
[9-07] Stop time: time at which setback is stopped
■
[9-08] Leaving water setback value
A Normal leaving water temperature set point or calculated
weather depended set point
B Calculated leaving water setback temperature set point

[C-00] Solar priority mode setting: for information concerning
the EKSOLHW solar kit, refer to the installation manual of
that kit.
[d] Local shift value weather dependent
Local shift value weather dependent
The local shift value weather dependent field setting is only relevant
in case weather dependent set point (see field setting
"[1] Weather
dependent set point" on page 14 ) is selected.
■
[d-03] Local shift value weather dependent: determines the
shift value of the weather dependent set point around
outdoor temperature of 0°C.

■
[E-02] Readout of the unit model identification (example: 11)
■
[E-03] Readout of the liquid refrigerant temperature
■
[E-04] Readout of the inlet water temperature
INFORMATION
■
Remark that the b icon will be flashing during setback
operation. The calculated leaving water setback set
point is
not shown during setback operation.
■
By default the setback function is disabled.
■
The setback function can be combined with the
automatic weather dependent set point operation.
■
Setback function is an automatic daily scheduled
function.
■
The setback function can be combined with the
schedule timer. When setback is active, the scheduled
space heating set point will be lowered with the [9-08]
leaving water setback value.
INFORMATION
Only applicable if [4-03]=4!
It is advised to set the start time of automatic storage
during night [6-04] on the moment that the setback function
starts [9-06].
INFORMATION
Pay attention not to set the setback value too low,
especially during colder periods (e.g. winter time). It is
possible that the room temperature can not be reached (or
it will take a much longer time) because of the big
temperature difference.
