insTallaTion
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.
