With this unit I understand you need a 99-500 speed control.
I'm also sure you need one in every bath that needs an exhaust.
I'm working with a customer that purchase this equipment for the install.i was not involve in the design process,and to tell the truth this is the first for me with this product.
So I'm looking at the materials list I got a box of timers
that control the lights in the grills,but nothing to control
the exhaust in the bathrooms.
If I may assume that we would need a speed control in every
bathroom.And how many controller can you hook to this board
that is label thermostat?
The installation is a little vauge to me.but then again I'm
simple.Thanks in advance!
