6.1 Setting Fan speed

The speed of the unit can be adjusted during installation according to required ventilation rate.

Figure 6.a below shows performance curves (for supply air and extract air) at different settings of the 0-10V signal to the motors. Airow and consumption

refer to the 2 motors.

Table 6.b indicates the efﬁciency of the heat exchanger and of the condensation produced in different climatic conditions, to help the installer or the designer

of the ventilation system to decide if to connect one or both condensation drainages.

High production of condensation is the direct consequence of a high efﬁciency level as well as of the humidity rate.

8 MAINTENANCE AND SERVICE

WARNING

Make sure that specic warnings and cautions in Chapter 2 “Precautions” are carefully read, understood and applied!

8.1 Components list

Fig. 8.a Internal components

8.2 Description of Components

Fans

The fans have external rotor motors of EC type which can be steplessly controlled individually between 10–100%. The motor bearings are life time lubricated

and maintenance free.

Filters

The ﬁlters are of ﬁlter quality G4 for both the supply air and extract air ﬁlter. The ﬁlters need to be cleaned regularly (and replaced when polluted) during

maintenance. New sets of ﬁlters can be acquired from your installer or wholesaler.

Heat exchanger

The unit is equipped with a highly efcient, counter-ow plate heat exchanger. Supply air temperature is therefore normally maintained without adding

additional heat. The heat exchanger is removable for cleaning and maintenance during service.

Condensation drainage

Depending on the relative humidity in the extract air, condensation may occur on the cold surfaces of the heat exchanger, on one side in winter time, on the

other side in summer time (ﬁg.6.b).

The condensate water is led out through drain plugs.

Thermostat

If external temperature is too low, the heat exchanger might get frosted, and therefore damaged. To avoid this, dedicated thermostat switches off the supply

fan if and when needed.
