Panasonic FV-VS15VK1 Whisper Select-Plug and Play Multi-Speed Module

Make sure you put the cover on the fan after you've installed this and want to check the sensitivity, otherwise the light from the night light may be too bright and cause the sensor to turn the light off, so the light blinks constantly when the room light is off.

great add on...thank you

I bought the motion sensor & nite light options for my 6 WhisperCeiling fans for my house after getting tired of hearing a jet engine in my bathrooms for years( the replaced model was a Nutone..a cheap builder install) some noteworthy observations. 1 : Motion sensor module: FV-MSVK1 As mentioned previously depending on which model exhaust you buy …there may be two timers if you add the motion detector module.(built into the exhaust itself PLUS the Motion Sensor Module you added on). The motion detector timer ( has a fixed cut off time of 20 minutes. But, if you add the Multi-Speed w/Time Delay Module (FV-VS15VK1) there is a separate timer you can set the fan to stop after 0 to 60 minutes, and it overrides the motion detector setting. 2: NightGlow LED Light Module: FV-NLVK1 The dial only adjust the ambient light sensitivity to tell it when to turn on. It DOESNOT adjust the brightness or output of the light itself 3: Condensation Sensor : FV-CSVK1 When the condensation sensor is used in conjunction with Multi-Speed w/Time Delay Module (FV-VS15VK1) the fan kicks up to high speed when the sensor detects moisture depending on your CFM setting. If no other modules are install then fan will run when moisture is dectected & shut of automatically after 20 min later 4: Multi-Speed w/Time Delay Module (FV-VS15VK1) You can set the CFM to 0 (zero) & then the fan ONLY comes on if motion is detected OR set it at a continuous speed to NEVER turn off Fan runs continuously at pre-set level, elevates to maximum level when a wall switch turns on OR detects motion OR condensation

Great little LED light. Works perfectly. Recommend adding it to your fan.

When CFM is set to 0, you can adjust the run time of the fan. My setup is the fan comes on with moisture using Condensation Sensor Module, FV-CSVK1. If I want to run the fan manually, I turn the wall toggle switch on/off/on and the fan will run per the preset of this module. If I move CFM off of 0, then the fan runs continuously at the preset fan speed for the duration of the timer. You can add a motion module too.
