Solar Pool Heater Controls
There are three ways to control the temperature of your solar heated pool.
A manual diverter valve gives you direct control over whether or not your solar pool heating system is working or not.
Automatic Controls are similar to setting the thermostat on your house. When the water temperature is cooler than your desired temperature, and there is enough solar radiation to heat the collectors, the system's pump is turned on.
Semi-Automatic Systems is a unique product by FAFCO. The system automates the heat production, though it does not limit the production of heat. It does not give you the precise temperature control you would get with automatic controls. It does automatically shut down at night or during cool weather so that the water's temperature is not lowered.
