• Technical features of the fan motor:
- With each EST fancoil unit there is the possibility to have different air volumes, ac-
cording to the use requirements. The relevant nominal air capacities are indicated
on Enclosure 3 of this manual and they are referred to standard fancoil units, with
clean filters, at the temperature of 20 °C, at sea level and without external static
pressure.
- EST technology is composed by a brushless motor combined to a dedicated
electronic device (inverter), managed by specific regulators. The controller uses
a modulating signal with 0-10Vdc tension in order to regulate the fan speed.
