Never install any wiring in a line voltage area unless the wire is rated for line voltage.
NOTE 1: If using a direct wired outdoor temperature sensor for automatic charge control, one outdoor
sensor is required for each heater that is installed.
NOTE 2: Dip switch #6 must be turned "ON" only if connecting a hard wired outdoor temperature sensor.
