Ventilation with Humidity sensor-- CA requirements

11 years ago

The state requires that we put ventilation in our bathroom that has a humidity sensor (and is energy star, but, whatever). We have a skylight in the bathroom, so we want to put a wall fan in the skylight tunnel to capture the humidity that travels up that tunnel. We are having trouble finding a wall fan of sufficient suction (>/= 110CFM) that has a built in sensor. So, two things:

1. any leads on a wall fan of that type? Google is failing me, we don't have a contractor to ask.

2. anyone know if inspectors will allow a separate humidity sensor that controls the fan, such as the one linked below? The problem I see with a sensor next to your light switches is that your room has to be awfully foggy to sense humidity way down at waist level as opposed to at the ceiling. I don't mind that, but maybe the inspector will....

You can always replace it, after the final inspection

This is is what we have. Recently passed inspection in CA. (I don't think it actually works all that well though as the room still seems humid to me when it shuts itself off.)

Is that just a sensor with no on/off switch? What brand? If I can find a sensor with no switch, we are thinking we could just mount the sensor up high. Maybe I'm way over thinking this--maybe I don't need a wall fan in the tunnel at all and a regular ceiling fan (with built in sensor) will suffice...

Also, crl_, what was your application? Why did you choose a separate sensor over having the built in sensor in the fan?

I can turn it on manually, but it turns itself off at some point. I don't know how it decides when to turn itself off. Our remodel is still in progress and we have only used the shower three times so far.

This is in a hall bathroom with a shower.

I did not choose. My GC said, you have to have a sensor, and installed this one. I had no idea they were required (it's new since our master bathroom two years ago) and no opinion on what to get.

Crl , That looks like a Leviton humidity switch. There should be an adjustment control for you to set for your humidity range. If you are using the manual function then the switch will turn off after 10 minutes. You need to set the sensor to auto function to meet your humidity requirements.
