Variable Speed Controller
Speed adjustment for the basic version can also be achieved with the use of a speed controller (stock reference
W300310). If a speed controller is used then the speed setting on the fan unit should be setting 3 – High Speed.
Follow the Installation and wiring instructions for the speed controller unit to install the controller correctly. A
variable speed controller should NOT be used with the timer version.
C.
OVER-HEATING PROTECTION.
The fan motor is fitted with Thermal Overload Protection. This is a one-shot thermal fuse. In the event of a fault
condition the fan will be automatically switched off. If this occurs isolate the fan, and call your service engineer.

1. At intervals appropriate to the installation, the fan should be inspected and cleaned to ensure there is no build
up of dirt or other deposits.
