Okay, what we have here is a freeze sensor.
A freeze sensor is a very simple device and you can place it in the basement or
anywhere else that may be at risk of freezing, in which case you will be notified
when that happens. It's a normally-closed device
and what you want to do on the back here, you can see where you'll run your wires
through there; it's easily mountable.
So, let's go ahead and begin.
You'll want to do that by removing the screws on the top and setting the cover
aside.
Use a small phillips head screw driver for this.
We have our common on the left, and our normally-closed on the right.
Common on the left;
normally-closed on the right.
Now, we're going to connect the 2- conductor wire using an end-of-line
resistor and running this in a series.
So, the yellow wire will attach over here to the normally-closed;
and the green wire will connect to a resistor which will terminate on a
common screw on the eft.
So, go ahead and do that as we've shown you in earlier videos.
As you can see we connected our resistor to our green wire, terminating the
resistor on the common
and our yellow wire directly to the normally closed terminal.
We did this by first feeding the wire through the back.
All that remains is to close the sensor; just line it up and
tighten the screws and then you're done.
Now, if you have any questions about how to connect a resistor or how much should
be stripped on the wire,
you can watch the previous video. The first one we showed you how to connect the
end-of-line resistor is
in the "Door and Window Contacts Video".
That will show you how to properly do a "Butt-Splice"
and connect the end-of-line resistor.
