[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.
■
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.
■ [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

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].
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.
