The module concept which is unique to iCON, gives one the option of determining how you wish to control your fan and based on your requirement select the appropriate module. Airflow has invested extensively in the research and development of our modules to bring our customers the most versatile controllability available in the extractor fan market. Our extensive range of control functions has helped the iCON product range become the leading brand it is today. The same module is compatible with all three size iCON’s – 15, 30 and 60. However, it should be noted that there are specific 240V modules and different low voltage SELV modules.Replacing a module is also a lot simpler and cheaper than replacing the entire fan. This plug in pull cord module (72573602) is for use in the 230v – 240v iCON 15 (72683501) iCON 30 (72591601) iCON 60 (72591701) only.This module will give the iCON the functionality of being able to turn the fan on and off at the fan. The pull cord will hang down from under the fan and switches the fan on and off when pulled and released. This module should only be installed by an approved and qualified person and in line with the instructions that come with each module.
