4. Operation
The HRU 400 is operated by means of a wireless control,
CO2
sensor
, RH sensor or the Spider climate controller, all of which
communicate wirelessly with the ventilation unit. The HRU 400
cannot be operated on the unit's interface.
On the interface, the filter warning can be reset using the button at
the top (A). The LED (1) shows the status in terms of messages
and errors. The wifi connection can be activated with button (B) and
the status of the appliance and that of the wifi mode is shown with
LED (2). In the event of error messages, both LEDs flash.
● Position 2,
middle position : for day or night when
more than one person is present.
● Stand 3,
high level : for when cooking, showering or bathing or
when many people are present.

Timer
The duration of the timer is determined as follows:
- Press timer button once: 10 minutes high.
- Press timer button twice: 20 minutes high.
- Press timer button 3 times: 30 minutes high.
After the timer has elapsed, the unit switches back to
automatic mode.
The Auto-Night setting ensures that the minimum ventilation
setting is increased so that you are also assured of an optimal
climate at night. You can use the
Auto-Night mode when using a
room without
CO2 sensor.
To activate the Auto-Night mode, press the Auto-button
twice
on
the wireless control switch or select Auto-Night mode on the
controllable sensor.

4.1. Ventilation modes
The ventilation unit is factory set to the automatic position as
standard. Using the Itho Daalderop accessories, such as the
wireless control switch, the sensors or the Spider climate
thermostat, the unit can be set to one of the following positions as
required:
● Auto mode,
automatic mode ; control based on existing
sensors (
CO2
and/or RH). The capacity is automatically
controlled between low and high position. Auto-Night
mode; control at night with an extra increase of the
minimum setting.
● Position 1,
low position : when one person is present during the
day or night or when nobody is present.
During Auto-Night mode, all sensors remain active and the
ventilation unit will normally respond to an increased ventilation
wish. The highest ventilation wish remains leading.
ä Attention
!
The Auto-Night stand becomes available when at least two
CO2 sensors are
used.
Note
When multiple sensors are used, the sensor with the highest
ventilation requirement is always leading.
Note
When using sensors, the maximum time that the ventilation unit
can be in a position other than the automatic position is limited
to 24 hours. After this period, the unit switches back to
automatic mode.
ä Attention
!
The Auto-Night mode does not switch off automatically after a
certain period of time. In the morning you have to switch on
Auto mode (or another mode) yourself.
