5.4 Calendar
Use this function to configure and change the setting of
each day of the week. Each day can be configured to run at
different fan speeds, as required. It is possible to copy the
configuration from one weekday to another. Here it is also
possible to choose ON or OFF, i.e. if there is nobody home
for a period of time, the daily settings can be turned off,
and the system will run according to a manual setting, for
example, level 1.
01 – Calendar
Choose between controlling the system manually or
controlling the speed (air exchange) and temperature
automatically, according to a fixed weekday program.
If the menu item is set to OFF, the system will be controlled
manually according to the selected speed and temperature.
If the menu item is set to ON, the system will be controlled
according to the weekday programs entered in menu items
02 to 08.
Setting range: ON/OFF.
Factory setting: OFF.
02 – Monday
Up to 10 switching times can be entered for one day. The
times can be input in a random order. Enter the hours in the
first column, the minutes in the second and the speed in the
third column. Use the fourth column to input the tempera-
ture difference by which the temperature should be low-
ered.
Example: If the temperature is set to 21ºC and you
enter – 2.0 °C, the system will aim at 19 °C.
If the speed has been changed manually with the key during
the daily operation, the program will return to the weekday
program when the next switching time passes.
Examples of a weekday program:
01 07:30 H3 - 0.0
02 09:15 H1 -1.0
03 17:00 H3 - 0.0
04 18:00 H2 - 0.0
05 23:30 H2 - 2.0
It is not necessary to use all switching times.
If there is 0 in the entire line, the control unit will skip it.
03 to 08
These days can be filled in individually in the same way as
under item 02.
09 – Copy day
Use this menu item to copy one day of the week to another,
where the same switching times, speeds and temperature
lowering are required. Example: From Thursday to Tuesday
5.5 User Menu
01 – Temperature
Use this field to set the room temperature. The room
sensor is installed in the control panel.
Setting range: between 10 and 30 °C.
Factory setting: 21 °C.
02 – Domestic water
Use this field to set the desired domestic hot water
temperature.
Setting range: between 0 and 55 °C.
Factory setting: 52 °C.
03 – Immersion heater
By configuring the set point to “ON”, the immersion heater
will automatically engage, if necessary. If the set point is
configured to “OFF”, the immersion heater will not engage,
even if there is a need for this.
When the fresh air temperature is below 0 °C, it is recom-
mended to connect the immersion heater as a supplement
to the heating of the domestic hot water, thereby reducing
the heating time.
Setting range: ON/OFF.
Factory setting: OFF.
04 – Timer levels 3 and 4
If the unit runs at speed 3 and 4 and the set point is set to
ON, the unit will automatically reconnect to speed 2 after
the number of hours set in item 17 of the Service Menu. If
the set point is set to OFF, the system will run at speed 3 or
4 until it is manually changed to another speed. The timer
can also be operated directly, with the key next to the sym-
bol for “Party mode” on the screen for daily operating
options.
Setting range: ON/OFF.
Factory setting: OFF.
05 – Filter change
There is a built-in filter timer that counts how long the sys-
tem has been running since the most recent filter change.
The set point can be set to between 1 and 12 months.We
recommend that the set point be initially set at 3 (3
months).
If the filters are too dirty after the set period, it is possible
to set the set point to a lower number of months. If it is not
necessary to change the filters after the set period, the set
point can be set to a higher number of months.
When the timer reaches the set value for filter change, the
“Change filter” alarm will flash at the top of the screen saver.
