Part #44 - 4200 Series

Outdoor Sensor - Knockout Style

Exploded View (Electrical Panel)

An outdoor temperature sensor, shipped inside the painted front panel, is recommended where PLC Communication is not being used. This sensor monitors outdoor temperature and provides this information to the system to adjust the core charging (See L010 and L011) and control the heat pump/air conditioner (See L046 and L047).

The sensor includes a mounting bracket and 40' of shielded cable that can be extended up to 250'.

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 transceiver. The Serenity 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.
