The Broan SmartSense system offers the required ventilation for indoor air quality. Other ventilation requirements are taken care of if the system is correctly installed. The ventilation level is set during installation based on the number of bedrooms and home square footage. Power outage does not interfere with the settings as they are stored in non-volatile memory. Monitor the fan on time and set automatic ventilation as required to obtain maximum energy consumption.

Additional features switched off at the factory include Delayed-off, Vacation, Automatic-Off, and Disabled modes. These are discussed in detail in the later section of this guide.

How LED Works

LED operates differently in run and Program/Feature Selection modes.

RunMode: LED is on once the fan is on manual ventilation and off when the fan is off. The LED is turned on by pressing ON PADDLE. It turns on for a short period every second when the fan is on automatic ventilation.

Program/Feature Selection Mode: LED turns on and off with a slow blink as the system is in Feature Selection or Program mode. LED is off once the pressed paddle associated with the Feature is off and on when the Feature associated with the pressed paddle is on.

Indoor Air Quality Network

One Broan SmartSense system is strong enough to offer the ventilation rates needed in big houses. However, it is advisable to install several of them for homes with more than one bathroom. Multiple installations will offer distributed ventilation in the entire house.

Multiple installations connect through the house's electrical power circuits to create an indoor air quality network. Interconnection pathways are referred to as links. To obtain maximum link performance, connect multiple installations to one electrical circuit. If it is not possible to connect them on the same circuit, try to maintain various installations on one electrical phase. However, if several installations have to be linked to different electrical phases, ensure to fix an SMSCPLR Broan SmartSense Phase Coupler close to the circuit breaker panel.

Multiple installations can work as independent entities though connecting them as an indoor air quality network is advisable. A single Broan SmartSense control is chosen as the system Master during the installation. Any control can be chosen as system Master, but master bathroom control is usually selected. A single control can connect to a maximum of 10 Broan SmartSense and link Logic units.

How to Connect Smartsense System

1. If there is no other switch fixed and well-marked on the frame, below the decorative plate, or written on the instruction paper as the main switch, then go to the main bathroom switch.

2. Set the main switch in program mode, press the SET button and hold it for 3 seconds until you hear a beep sound, then release it.

For it to be easy for a single-person installation, the main switch will wait for 6 minutes in Program mode for the slave link.

3. Light Emitting Diode (LED) should blink after every second (on and off); if it does not, repeat step 2.

4. Got to the first switch and link it as a slave.

5. Press the SET button and hold it for 3 seconds until you hear a beep sound, then release it.

6. Once you release the slave SET button, the fan and LED should turn on.

7. Press the slave off the paddle and release it manually to turn off the fan.

8. If there is more than one slave installation, move to the next switch and repeat steps 5 to 8. Else, continue to the next step.

9. When all slaves are set, exit the Main Program mode, move to the main switch, press the SET button, and release it.

10. The Master LED will blink fast to show system level and remain on as long as the fan is on. This confirms the Program mode exit.

11. Press the Main off the paddle and release it to switch off the LED and fan.

How to Adjust System Level

A homeowner, building science expert, or installer can set the Broan Smartsense ventilation system level.

1. System-level is usually adjusted from the main switch. If your house has many installations, then identify the Main control. It is usually documented in the master room or marked.

2. Highlight, circle, or mark the system level on one table with a home square footage and the number of your bedrooms. The installer can calculate different rates according to air infiltration measurements.

3. Highlight, mark, or circle the same system level in another table.

4. If your house system level is 30, the following steps are not applicable as 30 is the default system level.

5. Set the Main switch in Program mode, press the Set button, hold it for 3 seconds, and then release it.

6. Light Emitting Diode (LED) should blink after every second (on and off); if it does not, repeat step 5.

7. Press the slave off the paddle and release it manually to turn off the fan.

8. If there is more than one slave installation, move to the next switch and repeat steps 5 to 8. Else, continue to the next step.

9. When all slaves are set, exit the Main Program mode, move to the main switch, press the SET button and release it.

10. The Master LED will blink fast to show system level and remain on as long as the fan is on. This confirms the Program mode exit.

11. Press the Main off the paddle and release it to switch off the LED and fan.
