The Clipsal 2031VETF
Series is an electronic time delay switch which provides extended exhaust fan operations to ensure proper ventilation in bathrooms and toilets. It uses a single switch to operate both lighting and an exhaust fan. Both loads switch on simultaneously when the switch is operated, but when the lighting is turned off, the exhaust fan continues to run for several minutes.
Time Delay Intervals Available:
Series is adjustable to allow fans to continue to run from 3 minutes to 10 minutes (approximately) after the lighting is turned off. The delay adjustment is accessible on the rear of the device.
Turning on the switch will cause both the lights and the fan to operate. The electronic timer starts when the switch is turned off. The lights are controlled directly by the switch, however, the fan will run for its preset timer period when the lights are turned off. Turning the lights on and off again, while the fan is still running, will cause the timer period to restart.
The fan will activate for a timer cycle whenever power is re-applied to the unit. eg. initial installation, power failure/return, fan replacement.
