2.5 Optional Accessories
The following accessories are available for purchase
separately from your authorized Morningstar dealer:
Remote Temperature Sensor (Model: RTS)
The RTS measures battery temperature for accurate temper-
ature compensation and is recommended when the ambi-
ent battery temperature differs from the ambient controller
temperature by more than 5º C. The standard cable length
is 33 ft (10m).
NOTE:
The use of a Remote Temperature Sensor is
strongly recommended. Controller location, air flow, and
system power can drastically affect the local temperature sensor
reading. An RTS will provide optimal charg
ing performance.

formation, error indications, and self-diagnostic read-out.

The meter can be flush mounted in a wall or surface
mounted using the mounting frame (included). The RM-1 is
