Wet Switch?
Question:I have a dehumidifier that drains into a condensation pump. I would like to install a Wagner Wet switch so that if the pump fails the dehumidifier will turn off. The wet switch works with 24 VAC. I am not sure what that means. How can I set it up with a standard 110 outlet?
Answers:
The humidifier has a power supply rated at some determinable voltage.
The wet switch will provide a set of contacts to open the circuit of the power wire to the humidifier when it senses wetness, therefore the "switch contacts" of the wet switch need to be rated at the same, or greater, voltage as the voltage of the power wire to the humidifier.
Since the wet switch has an operating voltage of 24 VAC, you need a 24 VAC power supply to enable the wet switch to function. This can be supplied by a 120 VAC to 24 VAC transformer, available at most electrical supply stores, and electronic supply stores.
The transformer needs to be sized at a wattage rating of at least 125% of the rating of the wet-switch, or greater.
Provide 120 VAC to the transformer. The transformer will then produce the 24 VAC to provide power for the wet switch. Run the wire providing power to the humidifier through the switch contacts of the wet switch, so that it will be interrupted to "turn off" the humidifier when the wet switch gets wet, and you're done.
You need an adapter to go from 110 to 24 volts AC. The switch should have come with some instructions for this.
No, do not that. 24 VAC(volts alternating current) is the power your door bell runs off of. There is a tranformer that changes the 110 vac into 24 vac. The condinsation pump I have, has a connection for a wet switch. You will need to know what you have before you start hooking things up. you can ruin your stuff, or yourself.
