A control signal must be routed from the 230V line via the PIR or
light switch to the SL terminal on the unit and the factory link
between the terminals L / SL must be removed. (See figure
10). When 230V ac. is sensed on these terminals, the control will
be actuated.
NOTE:
If you do not require SL switching you should retain the
factory fitted link between terminals L & SL and set the run
on timer to 0 minutes.
Remote Run and Remote Fail connections
A volt free relay is included to provide status if any fan is running
(Maximum load is 5amp 230V ac.) When a fan is running, A&B
are connected. When a fan has failed, C&D are connected.

TWINFAN CONTROL
Using a Speed Control with a Quietwin
(SINGLE PHASE TWINFANS ONLY)
When using a Single Phase Twinfan it is possible to connect a
Speed Control to modify the output of the fan when commission-
ing the system. Details of suitable Speed Controls are shown
below.
When using a speed control with a single phase Twinfan, the
factory link between terminals L and FL must be removed.
The output of the Speed control should then be connected to the
FL terminal (See figure 12).
