Guide for ceiling fans
Step switching of ceiling fans with step-pull switch via bus system
All ceiling fans with 3-position pull switch can be controlled by a separate circuit. Here, the 3-stage -pull switch, which normally switches L against 1, 2, 3 and OFF, is replaced by a single-pole relay, which switches against 4 positions. An additional wire must then be pulled into the axis of the fan. The pushbutton (or bus pulse) then switches the relay per from OFF to the highest and then back to OFF via the medium and low speed stages.
The relay should be able to switch at least 0.5 amps of load.
NOTICE: Due to the large mass of the fan, it takes up to 30 seconds to reach the target speed when switching down. Impatient users it takes too long.
The forward/reverse circuit is similar: the 2-pole changeover switch is replaced by a 2-pole relay that changes the direction of rotation by pushbutton (or bus pulse)
NOTICE: Since the changeover of the direction of rotation may only take place at absolute standstill and the above solution offers no protection against switching during operation (exception: with bus switching bus logic), it can come in case of incorrect operation to damage the motor, which is not covered by the warranty.
A professional and proper conversion does not lead to loss of warranty!
This conversion may only be carried out by qualified personnel. Please consult your electrician!
