An outdoor temperature sensor, shipped in the electrical compartment, is required to be installed with the Comfort Plus. This sensor monitors outdoor temperature and provides this information to the system. The system responds by automatically storing heat in its brick core according to the outdoor temperature and the heating requirements.
The outdoor temperature sensor can be installed in one of two ways: direct wired to the system or wired to the Steffes power line carrier system. The Comfort Plus is factory configured for automatic charge control with a direct wired outdoor sensor. Refer to the Configuration Menu for information on the appropriate settings for the application.
NOTE: If connecting to the Steffes power line carrier (PLC) system, follow the installation instructions in the PLC system's Owner's and Installer's Guide.
Outdoor sensor wire MUST never be combined with other control wiring in a multi-conductor cable.
