Normal operation

When a temperature differential between the collectors and the bottom of the hot water system is reached, the microprocessor will activate the circulation pump which will circulate the water through the system.  The cooler storage tank water will pass up into the collectors and the warmer collector water will return into the storage tank.

The pump will continue to run until the lower temperature differential is observed (See Chart for the pump on and off temperature differentials)
