How are the wall controls powered? The Hunter Industrial Fan Team March 02, 2018 04:28 Updated Follow All of the touchscreens will be powered by 120v. The standard control does not require any additional power. Our controls can take 110V or 220V due our internal power supply. This needs to be noted when placing your order with your sales person.
