INSTRUCTIONS FOR WIRING HUMIDIFIER
On furnaces with output terminals ACC, or
EAC check output voltage to determine
that terminals are 115V. Connect on-off
switch in series with the hot wire.
On furnaces where it is desirable to use a
current sensing relay, the humidifier may
be wired from a continuous 115 volt
power source. Install the on/off switch in
series with the hot or black wire. Install
the Braeburn ® 229050 Current Sensing
Relay in series with the humidistat circuit.
The Current Sensing Relay will detect
furnace operation and supply power to
the humidifier accordingly.
