• Main menu: Menu levels V1, V2, Te, Ta and Ti
• Submenus (Parameter menus): LEDs 1 to 5
show the selected setting values.
• Bold = factory setting
• To select and save the setting value (parameter
value), press the <MENU> button.
Operating concept
1. Press <MENU> button for 2 seconds.
ð
Main menu V1 is selected, the 1st LED is lit
up red.
2. With the button <+> or <–>, select the menu
level V1, V2, Te, Ta or Ti, display with LEDs
(ascending/descending). The figure shows
menu level Ta.
3. Press the button <MENU> to change para-
meter level (LED flashes briefly 2x).
ð The last set value is shown (the corres-
ponding LED is lit up constantly*). Here, the
parameters of the respective level are avail-
able to you. Example Ta: 0, 3, 6,
15 , 24 or
30 minutes ( → Table).
* To switch off the Te start delay, Ta over-
run time or Ti interval time, push the <–>
button until the
V1 LED flashes .
4. Press <MENU> button for 2 seconds.
ð The setting is saved. All 5 LEDs switch off .
Adjustment hints
• Ti interval operation: : The unit is switched off
during the interval time. Then, the unit runs for
10 minutes with nominal ventilation (full load
level) V2 or in the set level 40 m³/h, 60 m³/h or
100 m³/h.
• Settings menu is automatically exited after 60
seconds without pushing buttons.
9.1.2 Automatic humidity function
The control continuously checks the humid-
ity during permanent base load. If the unit is
operated without permanent base load, the
unit starts at reduced speed (base load 20 m³/
h) every 2 minutes for 30 seconds and meas-
ures the relative humidity.
The start delay is deactivated with the auto-
matic humidity function turned on.
Once the unit is installed, it adjusts to the room
humidity prevailing at that time (relative humidity).
This humidity value is saved as the first reference
value. The reference value does not have to be
specified manually.
If the relative humidity falls below the reference
value during operation, the newly established ref-
erence value is saved. The lowest possible refer-
ence value is 45 % relative humidity.
If the room humidity rises quickly , the unit is
adjusted upwards in a continuously variable man-
ner (depending on the humidity) to match the hu-
midity. The maximum flow rate at 100 % r. h. is
40 m³/h, 60 m³/h or 100 m³/h, depending on the
setting of V2.
If the humidity falls below the reference value ,
overrun operation mode starts with the set over-
run time. The current reference value is then
saved.
If the humidity does not fall below the refer-
ence value within 60 minutes,
the unit switches
to the set overrun mode and then switches off.
In the case of
Light on, the unit starts up. If the
light is switched off, the unit continues to run until
the remaining overrun time has passed. The auto-
matic humidity function is then assigned max-
imum priority again and controls the unit as de-
scribed above.
NOTE! Information
• ER EC units can also be operated using a light
switch during operation with automatic humidity
function.
• The interval operation is deactivated during the
humidity operating mode.
