Remote Control ON/OFF:
"High", 2.4V to 24V (or open), unit OFF- Fan Off ; "Low", 0.0V to 0.4V (or closed), unit ON.
Source current is 1.6mA maximum at low level, and sink current is 1.0 mA maximum at high
level. The ±RC terminals are isolated from the a-c input terminal and the DC output terminals.
When remote ON/OFF is not in use, ±RC terminals must be shorted (use shorting link sup-
plied) for unit to operate.
