Differential Controller KIT

    This Basic analog differential controller kit or has an indicator that glows brighter in proportion to the temperature difference between solar collector and storage tank. This solar heat controller is capable of regulating AC or DC pumps with power requirements more than 300 Watts. As a matter of fact the relay has been tested for 24 hours under a constant load of 500 Watts with no signs of degradation yet the controller itself consumes less than1 Watt of power per hour. The Differrential Controller Kit is only $75 and I will assemble it for you for $85 and throw the shipping in for free as long as you live on planet Earth. Bigger is better when it comes to the surface area of collectors, but not necessarily better when it comes to the size of the controller. If, however, you need a temperature display for collector and storage  there are other options.

The Basic Differential Controller regulates a pump.

      

If you're going to regulate an AC pump you'll need a tiny DC wall transformer to power the controller. A simple 9 VDC or 12 VDC wall adaptor is all you need. If you are powering a DC pump with a PV power supply all you'll need a battery backup instead of a DC wall adaptor.

The BDC has the following features:
