DIRECTIONS
The HDFS3P1 is a 3 Amp, single pole Humidity Sensor and Fan Control
Switch. This sensor helps conserve energy and automates the fan in which
it is connected, which provides energy savings and reduces the possibility
of mold and mildew. When the humidity sensor detects excess humidity in
a room, it automatically turns on the ventilation fan. The sensor continues
to monitor the air and automatically turns the fan off when the humidity
level drops below its preset level.
WARNING
Turn the POWER OFF at the circuit breaker before installing the sensor
Read and understand these instructions before installing. This device is
intended for installation in accordance with the National Electrical Code
as well as local regulations. It is recommended that a qualified electrician
performs this installation. Make sure to turn off the circuit breaker or
fuse(s) and make sure power is off before wiring the device.
Use copper wires only. NEUTRAL WIRE IS REQUIRED.
WIRING DIRECTIONS
1. Connect RED wire from sensor to the FAN wire.
2. Connect BLACK wire from sensor to the HOT wire.
3. Connect WHITE wire from sensor to the NEUTRAL wire.

OPERATING INSTRUCTIONS
The HDFS3P1 features three adjustable humidity levels for customizable
control to suit the specific ventilation needs of the room. These humidity
levels are as follows:
1. High Humidity (80% RH)
2. Medium Humidity (65% RH)
*(default)
3. Low Humidity (45% RH)
Fan Mode: Manual ON, Auto OFF
a. The manual button is used to turn the fan off after a 20 minute time delay.
b. If the fan is in the ON state, the manual button is used to turn off the
fan before the time delay expires, the fan will immediately turn off and
the humidity sensor will stop working.
c. Turn ON the manual button and the humidity sensor will be operational
after 20 minutes.
Humidity Mode: Auto ON, Auto OFF
a. The Fan will turn ON automatically when preset humidity level is
reached and automatically turn OFF when the humidity level drops below
the preset.
b. If the humidity level is higher than preset for 3 minutes, then the fan will
continue to run for 5 minutes.
c. When the manual button is used to turn OFF the fan before the 20
minutes is reached, the fan will turn OFF immediately and the humidity
sensor will stop detecting. Only when the manual button is set to ON
then the humidity sensor will resume operation after 20 minutes. Expect
a 3 minute delay for the automatic sensor to turn on the fan.
