Hi,
I intend to air condition my entire house which involves a lot of room fans for equal air distribution.
The fans I can purchase here are high rpm high power types, far too loud at nominal power. Reducing fan speed with a phase contol unit would solve only a part of the problem. The ON/OFF cycles are controlled by a MASTER controller and the rpm regulation, done with normal (modified) dimmers should be left to individuals in the rooms. Setting the fan speed too low the fan won't start...
