P that would be great...but from past post about the elements going out and not knowing that make a buzzer or light that goes of when the elements go out or off.
McMaster Carr 6507K6 Electric Current Indicating Rings with wire leads. $9.73 ea
McMaster Carr 6507K7 Remote LED for Rings with Wire Leads?Red. $6.20 ea.
You need 1 - 6507K6 and 1 - 6507K7 for each heating panel you wish to monitor.
The 6507K6 is a small CT (current transformer). You run one of the wires going to a heat panel through the center of it. Mount the remote LED in the control panel face and wire it to the leads on the 6507K6. Do this for each heat panel you wish to monitor. When the heat panel is actually drawing power to heat the current running in the wire you ran through the 6507K6 will cause the 6507K6 to generate a small amount of voltage that will in turn light up the LED indicator. If the LED's are on then the heat panel is getting power and using it so in essence it is heating. When the LED's go off the power to the heat panel is off or the heat panel has failed.
