To active time intervals, set the
Reduction
schedule
activation
to
Yes
in
the
Temperature
set-point
settings
menu, which
will call up an additional parameter -
Temperature
reduction
schedule
.
Select
Work
Days,
Saturday
or
Sunday
. Then, it will be possible to define the beginning and the end of a given period (From,
To), and the value by which the temperature set-point will be lowered. Three time intervals are available per day.
See below an example of a night-time temperature set-point reduction from 10:00 p.m. till 06:00 a.m., and a daytime
reduction from 09:00 a.m. to 3:00 p.m.
CAUTION!
The
time
intervals
for
a
given
day
should
be
defined
starting
from
00:00.
The time zone editing window with sample settings for a
selected
day.
As illustrated in the example, the controller will set the desired temperature set-point reduction to 3°C, from 00:00 to 06:00
a.m. Then, from 06:00 a.m. to 09:00 a.m., the controller will leave the set temperature at the set-point level (no reductions).
The controller will set the desired temperature set-point reduction to 5°C, from 09:00 a.m. to 3:00 p.m. Then, from 3:00 p.m.
to 10:00 p.m., the controller will leave the set temperature at the set-point level (no reductions). From 10:00 p.m. to 11:59
p.m., the controller will reduce the pre-set temperature by 3°C.
CAUTION!
The
programmed
schedule
is
based
on
the
internal
memory
and
it
will
not
be
erased,
after
a
power
failure.
CAUTION!
A
time
interval
is
ignored,
when
the
value
of
reduction
is
set
to
“0”,
even
if
a
number
of
hours
has
been
defined.

Working
modes
To set the main operating mode and additional operating modes for the controller, according to which the control will be
performed, go to:
Menu
→
Working
modes
•
Recuperator
working
mode
- setting a working mode for the recuperator. Setting the mode to
Standstill
will stop
the unit, leaving only protective functions active. This mode can be used, for example, to prevent unpleasant odours
penetrating from the outside. If the
Continuous
operation mode is set, the recuperator remains switched on and
will operate, according to the settings. The unit can also work in additional modes:
Mode
1
,
Mode
2,
Mode
3,
and
Mode
4,
for which the user can define individual temperature settings and control parameters for the fans.
•
Additional
operating
mode
- activation of an additional, temporary mode of operation for the recuperator:
Exit,
Party
or
Ventilation
. Selecting
OFF
will disable the effect of the additional operating mode on the ventilation
system.
•
Overpressure
function
activation
(fireplace,
hood)
- allows the overpressure function to be
activated
or
deactivated
. When the function is activated, the extractor fan control will depend on the speed of the supply fan
and the set speed difference between the fans. The recommended operation mode of the ventilation system
working in combination with a fireplace with a closed combustion chamber and a kitchen hood, if it is necessary
to reduce the value of the extract air fan in relation to the value of the supply air fan.
Additional
operating
modes
The settings related to additional operating modes of the controller, in which the status of the air handling unit control is
changed for a specified period of time, can be found in:
