Using Two Exhaust Fans with AirCycler g2/FanConnect

A customer of ours recently asked if it was possible to operate two exhaust fans in two different bathrooms with the AirCycler g2 and FanConnect switch, to get double the exhaust ventilation counted toward the ventilation requirements. The answers is yes.


Here's how, using one FanConnect switch to control two fans:

1. By using a standard 3-way switch in the second bath and wiring to the FanConnect switch, the FanConnect can turn on the exhaust fan in the second bath at the same time it turns on the exhaust fan in the first bath. Otherwise, the second exhaust fan will continue to function normally, turning on when a user flips the 3-way switch.


2. Any time the FanConnect switch is turned on, both fans will run and that time as well as the following delay time will be counted as ventilation at the combined rate of both fans.


3. When required, the AirCycler g2 controller will activate both fans at the same time to provide needed supplemental ventilation.

4. When setting the Measured Exhaust Airflow in the g2 setup mode, enter the flow for both exhaust fans.

More information on the operation and installation of both the AirCycler g2 controller and the FanConnect switch can be found here.
