Its basic function is to monitor collector and storage temperatures and to automatically turn a small circulator ON or OFF at the appropriate temperature differentials.

How do I install a solar system?

Secure tank in event of an earthquake. Install a shut-off valve for the solar system so that the cold water supply is not interrupted. Install a T&P Relief Valve.
