Timer System
Warning! The timer circuit is under mains voltage. Ensure mains power supply is switched off
before making any adjustments.
The fan is operational after the control voltage is supplied by the external switch (e.g., by the light
switch) to the input terminal LT. After the fan is switched off the fan continues to operate within the
timer period set by the timer from 2 to 30 minutes. To adjust the run on timer, rotate the control knob
clockwise to increase and anti-clockwise to decrease the off-delay time respectively (see below
diagram). Please note the adjustment should only be done without the fan running.
The set includes a specially designed plastic screwdriver for timer setting adjustments. Only use the
plastic screwdriver to alter the turn-off delay time. Do not use a screwdriver, knife, etc. for adjustments
so as not to damage the circuit board.
