Phase Angle Power Controller With Integrate Flow SW Shutoff

[Cardinalbags]

I've posted in the past regarding use of flow switches to kill boiler power in the event of cooling water loss. I wanted to post my wiring diagram for this.

First I must give a tip of the hat and a thank you out to Mulekicker. It was from his posts on phase angle controllers that I took as my original design starting point.

Anyhow, here it is:

And finally here is a picture of the controller enclosure in operation.

The keen observers will notice the amp meter is not reading properly. It went Wango Tango on the first run. Although the meter face reads 0-50, it is not uncommon for manufacturers to make only 0-5 amp models and then it is required to use a coil transformer to scale up to the maximum faceplate value, in my case I would need a 5-50 CT. When I first installed it, it was inline and receiving the full amperage, hence the Ted Nugent reference.
