6.1 setting fan speed
The speed of the unit can be adjusted during installation according to required ventilation rate.
figures 6. a-d
below show performance curve at different settings of the 0-10V signal to the motors. Consumption refers to the 2
motors.
figures 6. b-e
indicate the data of the enthalpic heat exchanger.
tables 6. c-f
indicate the sound level at the different speeds.
