02 Technical Specications
The appliance is supplied ready to wire into
the fuse spur and operates fully automatically.
The extracted indoor air heats up the fresh,
clean outdoor air. That saves energy and
fresh air is sent to the required rooms.
The control system has three ventilation
modes. The air ow rate can be adjusted
per ventilation mode. The constant volume
control system ensures that the air ow
rate of the supply and extract fans is
always delivered despite any resistance
encountered in the ductwork.
The standard bypass valve makes it possible
to supply fresh outside air that is not heated
by the heat exchanger. Particularly during
summer nights it is desirable to supply
cooler outside air. In this mode the hot air in
the dwelling is replaced by cooler outside air
as far as possible.
The bypass valve opens and closes
automatically when a number of conditions
are satised (refer to the table below for
bypass conditions).
The operation of the bypass valve can be
adjusted in step number 5, 6 and step
number 7 in the settings menu (see page
41).
To prevent freezing of the heat exchanger
at extremely low outdoor temperatures,
the energiSava 300 & 400 features an
intelligent frost control. Temperature sensors
measure the temperatures across the heat
exchanger and, if necessary, the preheater
is switched on. This guarantees a proper
ventilation balance, even at very low outdoor
temperatures.
Bypass valve open
-The outdoor temperature is higher than 10°C and
-The outdoor temperature is lower than the indoor temperature in the
dwelling and
-The temperature in the dwelling is higher than the temperature set at step
no.5 in the settings menu
(set a standard at 22°C).
Bypass valve closed
-The outdoor temperature is lower than 10°C or
-The outdoor temperature is higher than the indoor temperature in the
dwelling or
-The temperature from the dwelling is lower than the temperature set at
step no. 5 in the settings menu minus the set temperature by the hysteresis
(tolerance) (step no. 6), this temperature is factory set at 20°C (22.0°C
minus 2.0°C).
