WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

3. Installation work and electrical wiring must be done by a qualiﬁed person(s) in accordance with all applicable codes and standards, including ﬁre-rated construction codes and standards.

4. Sufﬁcient air is needed for proper combustion and exhausting of gases through the ﬂue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

6. This unit must be grounded.

7. Do not connect this product as a load on a fan speed control or light dimmer.

8. Read and understand entire instructions before proceeding with installation.

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.

HOW SYSTEM WORKS

Broan SmartSense® system is design to provide recommended ventilation for desirable indoor air quality. Related ventilation requirements of *ANSI/ASHRAE Standard 62, “Ventilation for Acceptable Indoor Air Quality” are fulﬁlled when this system is installed accordingly. Ventilation level, which is based on home square footage and number of bedrooms, is easily set during installation. Power outages do not affect settings, since they are stored in power independent (nonvolatile) memory. Energy usage is optimized by monitoring fan on-time and adjusting automatic ventilation as needed. Indoor air quality is provided 24-hours a day, 7-days a week.

A single Broan SmartSense® system is powerful enough to fulﬁll ventilation rates for larger homes; however, it is recommended to use multiple installations for homes with multiple bathrooms. Multiple installations provide distributed ventilation throughout the home. Multiple installations are linked and communicate through home’s normal power circuits to form an indoor air quality network.

Broan SmartSense® controls are designed and factory set for multiple installation homes. If a single Broan SmartSense®

system is installed then System Level must be adjusted accordingly; otherwise, fan may run continuously.

Additional features, which are turned off at factory, include Vacation and Disabled modes. Vacation mode temporarily disables system until Master fan is manually turned on. Disabled mode removes system from automatic ventilation usage. Disabled mode does not affect manual operation.

HOW LED WORKS

LED works differently in Run and Program modes. Run Mode: LED is off when fan is off. LED is on when fan

is on manual ventilation; turned on by pressing ON paddle. LED turns on brieﬂy every second (fast-blink) when fan is on automatic ventilation; turned on by Broan SmartSense® system.

Program Mode: LED is on while SET button is pressed. LED turns on and off every second (slow-blink) when system is in Program mode.

INDOOR AIR QUALITY NETWORK

Multiple installations communicate through a home’s electrical power circuits to form an indoor air quality network. Communication pathways are called links. A phase coupler

is required if multiple installations are connected to both electrical power phases.

Individual systems in a multiple installation home can operate independently; although, it is recommended to link multiple installations as an indoor air quality network. If a

single Broan SmartSense® system is installed or independent system operation is desired, proceed with “How To Set System Level” section. If System Level is not adjusted, fan may not shut off automatically or run unnecessarily too long.

One Broan SmartSense® control is selected as system Master during set up. Any control can be selected as system Master, but typically master bathroom control is chosen. All controls are factory set as system Masters.

SmartSense® controls that are linked to Master control are called Slaves. One Master control can link up to 10 Broan SmartSense® Slave controls.

HOW TO LINK SMARTSENSE® SYSTEM

1. Unless another control is designated and clearly marked on frame, under decorative plate, or documented on this instruction sheet as Master control, go to master bathroom control.

2. Put Master control in Program mode; press and hold SET button for 3-seconds and then release it.

Note: Master control will automatically exit Program mode

after 4-minutes.

3. LED should be turning on and off every second (slow-blink); if it isn’t then repeat step 2.

4. Go to ﬁrst control to link as a Slave.

5. Press and hold SET button until fan turns on. If fan doesn’t turn on in less than 5-seconds, make sure Master is in Program mode; which is indicated with LED slow-blink.

Note: At same time Slave turns on, Master fan turns on.

Master fan should turn off automatically in less than 15-seconds.

6. Release Slave’s SET button.

7. If Master control has not automatically turned Slave off then press Slave’s OFF paddle to manually turn it off.

8. If there are more Slave installations then go back to Master control and repeat steps 2 through 8.

Note: Master control will automatically exit Program

mode 4-minutes after it is started. Slave link needs to be made before Master automatically exits Program mode or Master control’s Program mode needs to be started again.
