Edward Rodriguez video transcript - Low Voltage Wiring (Training Transcript)
Speaker: Edward Rodriguez
Hey guys, welcome back to HVAC Tech Academy. I’m Ed and today I’ll be showing you some low voltage wiring.
So, we’re going to start over here at our air handler. In this case, you can see this would be our low voltage wiring. You see this low voltage wiring also connects to the back of our thermostat back here as well.
So now our thermostat, our low voltage wiring is always going to be 188 proportions of the AWG. The eight wires being of 18 AWG. Behind your thermostat here is where you’ll also see your connections. C for your common, R for your 24 volts, G for your blower motor, Y for your outdoor contactor, W for your heat, and O for your reversing valve.
Behind the thermostat as well is where you can see that the thermostat makes these connections. If everything is working properly, the thermostat should make these connections and these connections can always be tested either behind the thermostat for continuity or you can always check your voltage here.
In this instance, we have a control. You would use your multimeter volt AC and we can check to see where we have voltage in each and every point from R to common, R to O, R to G to Y to W, so on and so forth.
All right. Well, that was low voltage wiring. Again, my name is Ed. See you guys next time.
