FR3-A2A, adjustable CT, delay on/off timer
The ABC FR3-A2A is designed to switch when a signal is received from the monitored circuit via the on board adjustable current sensor. When monitoring the power to lights, fans, dryer, GPO or a range hood the ABC FR3-A2A unit can be used to operate a secondary fan such as a booster fan or fresh air fan or even a damper motor. In the example shown below the fan will turn on 1 minute after any of the lights are turned on and will continue to operate unit the last light is turned off and 10 min (adjustable) has elapsed.
The delay on timer is included for energy saving, as this allows some one to enter a bathroom for a short time without needing the fan therefore only using the fan when really needed.
