USER GUIDE
ABOUT VENTILATION
The ventilation unit should never be switched off. It is important to always ventilate with a high enough effect! If the ven-
tilation is insufficient the humidity indoors becomes too high and condensation can appear on, for instance, all the win-
dows. A relative humidity of 40 - 45 % indoors is recommended (room temperature of 20 - 22°C). At these levels condensa-
tion will not form and the humidity will be at a healthy level. The humidity of a room can be measured with a hygrometer.
When the humidity rises above 45 % one should increase the ventilation and when the humidity goes lower than 40 % one
should lower the ventilation.
Check regularly that the filters are not dirty! During winter the exhaust filter become dirtier more quickly than the supply
air filter. As a result of this the airflow lessens, which leads to lowered humidity indoors. This also leads to lower temperatu-
res. Check the filters each month! At each filter inspection, check that the heat exchanger is functioning correctly, meaning
check that it is rotating. Cover both the outside air intake and the waste air outtake if the unit is not to be used for a longer
period. This way you stop moist from condensing on e.g. the fans electric motors.
CONTROL PANEL
Fan speed
There are 4 green LED lights for fan speed indication (minimum speed at bottom and maximum speed at top). Below the
green LED’s there is a button (1) for cycling through the fan speeds (see diagram on next page). The lights will turn on one
at a time and they flash if in ‘over pressure’ mode.
Supply air heating
The ECE model’s control panel has also a button (2) to turn on the electrical boost heater and to choose the supply air tem-
perature. The four green LED lights show the supply air temperature as follows: +17°C, +19°C, +21°C, +23°C. The higher
temperatures may can be difficult to reach with fan speeds three and four.
Heat recovery
On the control panel there is a button and green LED light (3) for heat recovery. The heat recovery wheel is rotating and
operational when the light is on. It is possible to turn off the heat recovery e.g. in summertime when the outside air tem-
perature is the same as inside the house or when you want to take cool outside air into the house. If the heat recovery is
turned on on a hot summer day it will work as a cooling recovery unit. It is possible to turn off the heat recovery unit only
when the outside air temperature is above +15°C (setpoint can be adjusted b10...+20°C from the main board
potentiometer, see electrical connections). The heat recovery will start automatically when the outside air temperature
drops below this setpoint.
Service / alarm
Service / alarm is indicated with a red LED light (4). It illuminates automatically every three months as a reminder to check
the condition of the filters. The alarm is de-activated by switching off the electricity supply to the ventilation unit. The red
LED will flash if supply air temperature drops below +5°C. It will also flash if the electrical heater’s over heating protection
has tripped, emergency stop is activated (if one is connected) or an external alarm is active (if connected).
