I have a bunch of these solar differential controllers. They have differential and set point functions, as well as basic data logging, hours of pump run, BTU calculation if you enter a flow rate.

Intended for off-grinders with battery systems but they work nicely with any 12VDC like a RV or your truck. Usually connected to the B&G/ Laing solar strong 12-24VDC circulators but will run fans, lights, etc within the relay capability.
Or use it as just a 4 temperature digital display. 4 sensors included, spare fuse, etc.

These are Resol brand controls, very nice German quality. New in the box, old inventory, no warranty. Cover the shipping cost, probably 20- 25 bucks and I will mail one to you. PayPal, Venmo, or send a check :)

A short video on how to make adjustments within the different pre-programed arraignments. A link to the current manual, and a video showing how to make adjustments.

    I got one of these from you a year or two ago and love it, I would love another one for my shop instead of swapping this one between buildings if you have enough available but don't want to be greedy if someone else could use your stock!

    Sure, send me you mailing address again. I’d like to see them put to use.

    Hi Bob, This is too good to pass up. Could I get two?

    Yours, Larry
