6 COMMISSIONING
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 curve at different settings of the 0-10V signal to the motors. Consumption refers to the
2 motors.
Figure 6. b
indicates the data of the enthalpic heat exchanger.
Table 6. c
indicates the sound level at the different speeds.
