I looked up the specs on this
"Combined Amps 12.2 "

A 15a switch will be fine since switches are selected based on the
load, not the circuit ampacity.
The switch that says "max 3a" is only good if you are switching the
fan. The heater would smoke it pretty quickly.

All of the wire in the wall needs to be sized to the over current
device (20a=12g copper). There are some exceptions but this is not
one.


Everything you have said is basically what I expected to hear.

I have a couple of other questions, based on the info in this document:

https://www.acwholesalers.com/hvac/p...FV-WCSW-sb.pdf

First "question" - I'm pretty sure I've got this right, please verify.

The first switch in the document - FV-WCCS1 - is what I am planning on
using for the fan. It's a Humidity Sensing switch rated for 15A.

The last switch in the document - FV-WCD01 - is what I am planning on using
for the heater. It's a count down timer switch rated for 20A.

That seems OK to me.

Second "question" - mostly just a curiosity.

I'm a bit confused by the switch directly above the FV-WCD01, specifically
FV-WCSW41. It contains 3 independent rocker switches, each rated for 15A,
but also says that the total switch amperage is 20A. It also says that it
is designed for the FV-11VHL2, which has a fan, heater and light. So does
that mean that if I wanted to, I could use a 15A switch for the heater in
my FV-11VH2, which is basically the same unit but without the light? In
other words, if I had 2 separate 15A switches, one for the fan and one for
the heater, that would be OK, right?

Thanks again for the help.
