5. Operating Instructions

The EQUATION SLIM Bathroom Fan operates automatically based on its integrated humidity sensor and timer.

5.1. Humidity Sensor Adjustment

The humidity sensor can be adjusted to activate the fan when the ambient humidity level exceeds a set threshold. The adjustable range is typically between 60% and 90% relative humidity.

• To adjust, carefully remove the front cover of the fan.
• Locate the humidity adjustment dial (often marked with a '%' symbol).
• Turn the dial clockwise to increase the humidity threshold (fan activates at higher humidity) or counter-clockwise to decrease it (fan activates at lower humidity).
• Replace the front cover securely.

5.2. Timer Adjustment

The timer function allows the fan to continue operating for a set period after the humidity level drops below the threshold or after the light switch (if wired to it) is turned off. The adjustable range is typically between 2 and 30 minutes.

• To adjust, carefully remove the front cover of the fan.
• Locate the timer adjustment dial (often marked with a 'min' or clock symbol).
• Turn the dial clockwise to increase the run-on time or counter-clockwise to decrease it.
• Replace the front cover securely.

Note: Always ensure power is disconnected before adjusting internal settings.
