how important wet switch hvac safety
Power supply to the Wet SwitchÂ® is 24VAC, the standard power available on most air handler units. This makes hookup quick and easy. There is no need to run different power to the switch. When the Wet SwitchÂ® activates, it locks out the call for cool circuit on the air conditioner until the switch is manually reset. This prevents continuing damage in cases where the overflow water drains out of the pan, onto the surrounding ceiling. Download Images.
