SWITCHING ON/OFF THE FIRE BOOSTER
When initiating a fireplace, such as a fireside, the fire
booster can be switched on.
With the fire booster switched on, the supply air ventilator is
set to level 3. The room ventilation unit operates at the
nominal volume flow rate. The supply air ventilator oper-
ates at a speed of 100 % and the exhaust air ventilator at a
speed of 50 %.
If the supply air temperature (T2) falls below 9 °C before the
period of 7 minutes has expired, the room ventilation unit
automatically switches back to the last operating mode. The
unit operates again at the speed of the previous operating
mode.

Note:
The fire booster cannot be operated at outside tempera-
tures below -13 ° C. For this purpose, installing a pre-
heating is required (accessory).
3.9.
The bypass is available as an accessory. It allows bypassing
the heat exchanger and thus, the cooler outside air is not
heated.
There are two versions of the bypass available.
• Version A is an exhaust air bypass. The exhaust air by-
passes the heat exchanger and thus, the supply air is not
heated.
• Version B is a supply air bypass. The supply air bypasses
the heat exchanger and thus, the supply air is not
heated.
3.9.1.
The automatic bypass can be used at night in summer for
example. The outside temperature must be higher than
15 °C , but must be lower than the room air temperature.
In the installer menu, the temperatures can be set from

3.9.2.
At lower outside temperatures, e.g. in spring or autumn, the
building can be cooled down by manually switching on the
bypass, without a heat recovery being used.
The bypass will then be activated for 6 hours, as long as the-
temperature difference of 2 °C between of the outside air
