BRIEF DESCRIPTION

Quiet(-Style) 100 DC is an axial fan for extract ventilation of small and medium-sized domestic spaces heated during the cold season. The fan fits 100 mm air ducts. The fan is equipped with a back valve to prevent back air flow during the fan standby.

OPERATION GUIDELINES

The fan is connected to 220-240 V 50/60 Hz or 12 V 50 Hz single-phase AC mains depending on the model and is designed for continuous operation without disconnection from the electric mains. The air flow direction must match the arrow on the fan casing. Ingress protection rating against access to hazardous parts and water ingress is IP45.
The fan is suitable for operation at ambient temperatures ranging from +1 °C to + 40 °C.
The fan is rated as a Class II electrical appliance (220-240 V 50/60 Hz).

Installation And Set-up

FAN SETUP

THE TIMER BOARD IS UNDER MAINS VOLTAGE.
MAKE SURE THE FAN IS COMPLETELY DISCONNECTED FROM THE POWER MAINS BEFORE ADJUSTING

The fan is set up by changing the DIP switch position. To access the DIP switch take off the face panel and remove the rubber plug. The fan is supplied with a special plastic screwdriver to toggle the DIP switch without damaging its components.

Fan Setup

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD

FAN OPTIONS

(S)Т — fans are equipped with a deactivation delay timer. The timer activates upon control voltage application to input terminal LT by an external switch (e.g. indoor light switch). Upon control voltage removal the fan continues to operate for the period of time set by means of a DIP switch. VT models are equipped with a cord-operated switch.
ТР — fans are equipped with a motion sensor and a deactivation delay timer. The fan operates in one of the four modes set by a DIP switch.
(S)ТН — fans are equipped with a humidity sensor and a deactivation delay timer. The fan operates in one of the four modes set by a DIP switch. VTH models are equipped with a cord-operated switch.
