Frost Protection Mode - Rinnai Prestige Operation & Installation Manual

FROST PROTECTION MODE

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 temperature
on the roof drops low enough, to prevent freezing of the collectors.
Standard operating mode is designed for systems using flat plate collectors. Low temperature mode MUST be
used for systemswith evacuated tube collectors. Refer to the warranty booklet for more details.
