NOTE: Each terminal accepts 22-16 AWG wire.
1. Remove applicable knockout(s), (1), from bottom of
enclosure in low-voltage connection area.
2. Connect the peak control wires to R and P.
NOTE: Outdoor transceivers have a factory-installed
outdoor temperature sensor (thermistor), (2). If the
transmitter is being installed in an area where an
accurate outdoor temperature is not available, the
thermister should be removed and an outdoor
temperature sensor (Order Item #1302044) should
be installed.
3. If installing an outdoor temperature sensor, connect the
outdoor temperature sensor to the two OS terminals. The
outdoor sensor must be placed in a location where it can
accurately sense outdoor temperature and is not affected by
direct sunlight or other abnormal temperature conditions.
NOTE: If necessary, the outdoor sensor can be extended
to a total of 250 ft. No other loads can be
controlled or supplied through this cable. It is for
connection of the outdoor sensor ONLY.
