Install controls and wire them as shown. Use following guidelines:
•IMPORTANT:
QTXE080 Ultra Silent™ fan must be wired to SMSC080 SmartSense® control.
QTXE110 Ultra Silent™ fan must be wired to SMSC110 SmartSense® control.
•Use minimum 75 °C rated electrical wiring.
•Except for required neutral wire, these controls install like normal switches. Make sure electrician knows each control location must have a neutral wire. Neutral wire at switch locations may be code requirement or regular practice in installation municipality; but unless explicitly specified, electrician might not install it.
•Specify deep device electrical boxes where controls will be installed. These controls fit in most North American electrical boxes; however, deep boxes provide extra working space which eases installation. Labor cost savings can offset higher box costs, which is usually less than a dollar over standard depth boxes. Use boxes that have 18 cu. in. minimum volume and are at least 1‑1/2 in. deep.
•All controls must be grounded using attached ground wire.
