Timer System
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.
Warning! The timer circuit is under mains voltage. Ensure mains power supply is
switched off before making any adjustments.
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.
