FROST PROTECTION MODE ON SOLAR CONTROLLER

• The Solar Controller has two different temperature modes. Low temperature mode and

standard operating mode. When the controller is in low temperature mode, the pump will

circulate water to the collectors when the temprature on the roof drops low enough, to prevent

freezing of the collectors.

• Systems installed with E-Frost Collectors: Controller MUST be set to low temperature mode for

the warranty on the collector to be valid. Refer warranty booklet for more details.

• Systems with other types of collectors can be set to standard operating mode.

• The factory default is Low Temperature Mode.
