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.
