Overvoltage Protection
When the Power Supply goes into an overvoltage condition, the output is cut OFF. To restart
(reset) the unit, it is necessary to remove, then reconnect the a-c input power after about 30
seconds, or to open and then reclose the RC terminals.
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.
When remote ON/OFF is not in use, ±RC pins of connector CN2 or CN3 should be shorted
(use connector supplied) for unit to operate.
