SAFETY
General Electrical safety
Always check that the equipment supply voltage
is switched off before opening the service hatch.
Only an authorised electrician may perform any
actions in the electrical box.
Follow the local regulations on electrical
installations.
In case of malfunction, always find out the reason
for the malfunction before starting the unit again.
Wait for two (2) minutes after switching off
the power of the unit before commencing the
maintenance. Although the power is switched
off, the fans continue running and the heating
element stays hot for a while.
Check that the unit is entirely isolated from the
mains before conducting any voltage tests,
insulation resistance measurements or other
electrical work or measurements. Such work may
damage the sensitive electrical devices.
Control devices used in the ventilation units may
cause leakage current. It may affect the operation
of the residual current devices.
All ventilation units with a control system must be
equipped with an over-voltage arrester.

INSTALLING EXTERNAL SENSORS
The eWind- automation is already at the factory prepro-
grammed for an external humidity (RH) -sensor. If the
external sensor is a humidity sensor, changes to the sensor
parameters are not required. If the external sensor is a CO2-
sensor, the changes to sensor parameters shown on the
next page must be done from the eWind operating panel.
