How Does My Float Switch Work? (VIDEO)

In this video I take you on a quick walk through of how your float switch is wired in to your system and how it protects your home. 

Here is the break down. 

High voltage power comes into your HVAC system and is run through a transformer that lowers it to 24v (low voltage). That low voltage is sent down to your thermostat normally via a red wire. This low voltage is how your thermostat controls your system. This wiring is referred to as thermostat wire, or control wire, for obvious reasons. 

The float switch is then entered into the 24v circuit by tying it into the red wire. Now, the red wire comes from the HVAC system and ties into the first wire from the float switch. Then the second wire from the float switch connects to the red wire going to the thermostat. 

We have now inserted a safety switch into the control wiring.

If your main drain clogs and water backs up, it will back up into the float switch which will then shut off the power to the thermostat and thereby the HVAC system. If this happens give us a call and we will come unclog your drains and get the system back up and running in no time.

If your system is in your attic you can see the benefit of turning off the power before it floods. That’s why float switches are referred to as ceiling saver switches.
