This is a digital control panel that is wired for operation with a processor that runs on 120 volts.
The power cord is 14 gauge (15 amps) but the relay(s) inside can handle up to 240volts at 30 amps if required.

Unit comes complete with the thermocouple and 6 feet of cord. It also comes with mounting feet so you can screw the box right into the sheetmetal of the water heater for fast installation.  

You need only run the wires from the heater element and pump into the box.

Price is $195 +shipping for the basic 115 volt unit.  We also have 220 volt units available and units with shut down timers!!   Power multiple 220 volt heaters and a 220 volt pump and shut it all down at the same time.   Email me through my website www.MurphysMachines.com

This panel box is a modular unit design and we have many standard configurations available.  Just ask!

These panels can be configured for almost any basic control requirement.

This one controls a 1.5hp-220volt pump and four (4) 220volt heaters and is equiped with a cycle button for timed shutdown when the process is complete. A little automation goes a long way!

Does the controller have any agency approval?  Note that if you're offering this for general sale, that most municipalities require such equipment to have an NTRL listing (UL, ETL, CSA, FM, etc.)
