The final system programming is complete. A "Heat Monitor" statement has been built for the Domestic Hot Water and Space Heating tanks. The heat energy is measured in Watts and is calculated from the temperature differential across the collector and the flow rate during the period that the pump (either one) runs.
The programmed parameters are: collector input flow temp, collector return flow temp, flow rate (set at 1 gpm - actual measured flow), and pump relay "on" time.
The wattage is a "totalized" acculation in watts. There are two seperate "statements" that totaled, represent the solar energy gathered, stored and delivered to the home.
