Energy Saving Tips
Although this unit is used to increase comfort and ener-
gy savings, it is possible to maximise energy savings if
you observe the following.
h
Note
At low ambient temperatures below the room
temperature, you will reach the maximum ener-
gy saving if you keep the windows closed and
ensure the necessary air exchange by the oper-
ation of the domestic ventilation unit.
It goes without saying that venting the room is always
possible by opening the windows.

Bypass (optional)
The device can be equipped with a bypass, which is fit-
ted on the top of the device, see fig. 4.2.
With a bypass installed the user may operate the so-
called "free cooling mode" during the summer months
with the outside temperature falling below room tem-
perature during the night. The cooler outside tempera-
ture will not be warmed by the device before it was
blown into the room. To protect the bypass valve from
dirt, we recommend an outside air filter of the filter
class at least G3. The filter is installed on site into the
outside air duct, possibly close to the air inlet.

Switching-on and -off of the device
The domestic ventilation unit is supplied with electrical
power via a 230 V mains line.
• Insert the mains plug into the 230-V socket.
The electronics of the ventilation appliance is starting.
The display shows the unit type (display "RECO 275 or
350") and then, after about 3 seconds, the indication
switches to the basic display.
• To switch off the unit, pull the mains plug out of the
plug socket. Using the "off" menu point on the remote
control switches the unit to the lowest fan speed.

Functional Overview of the Digital Remote

The domestic ventilation unit is equipped with a digital
remote control to operate the unit.
The remote control has three buttons as well as a dial
(Vaillant operating concept "turn and click") to set vari-
ous operating programs. In addition, you can set special
functions as well as a time-controlled function of the
ventilation unit.
