• 3 speed fan through optional TRIO-S controller (code 12871), consisting of:
• capacitor start induction motor equipped with thermal overload cutout and self-lubricating bushings,
• forward centrifugal impeller.
• Nominal diameter 100 mm.
• Electronic pcb with humidistat function piloted by RH% sensor (4 preset thresholds: 60%, 70%, 80%, 90%, selectable during installation), designed to switch on the fan automatically.
