Humidity Sensor and Fan Control
SPECIFICATIONS
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
- Connect RED wire from sensor to the FAN wire.
- Connect BLACK wire from sensor to the HOT wire.
- Connect WHITE wire from sensor to the NEUTRAL wire.
- Connect GREEN wire from sensor to the GROUND 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:
- High Humidity (80% RH)
- Medium Humidity (65% RH) *(default)
- 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.

TROUBLESHOOTING
The switch button is not functional:
Check if the device is wired properly. This device requires a NEUTRAL wire for operation. Often the WHITE wire is used as a LOAD wire. Be sure to test ALL wires. Also make sure that the HOT and LOAD wires are not reversed.
Press the Fan Button:
-
If the load does not work and the indicator light is not on.
TURN OFF the power at the circuit breaker then check wire connections.
Confirm that the NEUTRAL wire is connected. -
If the Humidity Sensor does not turn on the fan.
Change the humidity level to match the appropriate condition or manually turn ON the fan, after 20 minutes the humidity sensor will be operational.
