Remote Temperature Sensor RTS

The RTS may be used with Morningstar’s ProStar™ , Sunsaver MPPT, Sunkeeper, Sunsaver Duo and TriStar™ solar controllers. The RTS should not be used with any other controllers. Also note that the RTS may only be used with ProStar manufactured after May 2001 (bar code label: after 0122xx - year 2001 / week 22). The ProStar has on-board temperature compensation, and the RTS provides more accurate compensation by measuring temperature at the battery. Use of the RTS is recommended whenever the temperature at the battery will be more than 5°C (9°F) different than the temperature at the controller. The TriStar has no on-board temperature compensation, and the RTS will provide temperature compensated charging. Use of the RTS is recommended only for battery charging or diversion control modes (not for load control mode) and whenever the temperature of the battery varies more than 5°C (9°F) during the year.
