what is this thing ? Westinghouse LMT-100 Load controller

Post by dacflyer » Mon Feb 18, 2013 2:01 pm

i know it is some sort of a load controller, this unit looks like a electric meter, but it is inside the house, and connected to ( or it was ) a water heater.
my question is. how did this work, and was it a self learning device ? or did the electric company control it ?
i tried to find info on the web about it. but had no luck...

Here is my guess.
Some electrical utilities (at least here in Canada) offer some kind of monetary discount if your hot water heater does not consume electrical power during peak periods, like 5 to 8 PM when ovens are in use. That device probably disables the heating coils at certain times. Could that thing inside it that looks like a meter actually be a timer?

Why don't you give your electrical utility a call and ask?

Side Note:
Our utility company here in Maryland uses radio controlled switches to shed the AC and/or water heater load during peak demand periods.
There is no set timed cycle, they do it based on load demands. You can enroll in a higher load shed percent and get a larger rebate if desired.

i have tried to ask a few guys i know with my local utility. they said these units were offered by another utility co. years ago. but he did not know how they operated.
i am not sure if it was something pre-programmed or if it was remotely controlled.
it has 2 leds on it.. a red one and a yellow one. but no markings of its state.
