CONTROL OPERATION
HOW THE LED OPERATES
When the system is running the fan automatically, the LED will be
off with a quick blink each second. The control also uses this mode
to indicate when it is in the Program Mode.
When the control is off (turned off manually or by the program), the
status LED will be not illuminated.
When the control is manually turned on, the LED will be on.
HOW THE MASTER & SLAVE CONTROLS WORK
The controls in a system are defined as a Master and Slaves. Any of
the SMSC080 or SMSC110 controls can be designated as a Master.
All controls initially (out-of-the-box) function as a Master.
Master Control
The Master is the control used to initiate the linking and program-
ming process. Once a control is linked to another control, a Master
Slave relationship occurs.
The Master control should always be installed in the home's master
bathroom. Installing the Master in the master bathroom makes it
easier for the homeowner to determine the location of the Master
control. Only the Master control can place the system in vacation
mode, disable mode, change the system level, etc.
The Master control does all the calculations required to determine
how much fan on time is needed to meet a home's ventilation re-
quirements. Ventilation requirements are determined by the system
level setting. The other controls (Slaves) will be linked to the Master
so that they only operate when commands are received from the Mas-
ter control or when manually operated.
Slave Controls
Slave controls accept instructions from the Master control. Slave
controls also communicate to the Master when the home's occupants
manually operate fans. The time that the fans are operated manually
is credited towards the home's ventilation requirements determined
by the system level setting.
Install the controls and wire them as shown. Use the following guidelines:

controls will be used. While the Broan SmartSense
offered by all North American electrical boxes, the deep models have extra work-
ing space and make the installation go a little easier. Deep boxes only cost a few
cents more than normal depth models. Look for single-gang boxes that are 22 cu.
in. or higher and double-gang boxes that are 36 cu. in. or higher.
HOW TO FORM A NETWORK
Controls are linked together so that automated commands for the

when the homes occupants manually operate fans. The time that the
fans are operated manually is credited towards the homes ventilation
requirements determined by the system level setting.
Program Mode
At the Master control (in the master bathroom), use a screwdriver tip
to gently press and hold the SET button for 4 seconds, then release.
The SET button is the clear button at the bottom of each control
(reference drawing of controller face). LED will flash continuously to
indicate Program Mode. Repeat this procedure if LED does not flash
continuously.
Linking Controls (Slaves)
1. While in Program Mode, press and release SET button on Master
control gently with a screwdriver (approx. 1 sec.). A flashing LED
will indicate if the Master control is in Program Mode.
2. At the Slave control use a screwdriver tip to gently press and hold
SET button until the Slave fan turns on (approx. 3 sec.). Release
SET button. When a link is established both the Master and Slave
fans will turn on.
3. The Master's fan will turn off automatically after approx. 15 sec.
4. After the Master's fan turns off, press the Slave control's paddle
OFF to turn the Slave fan off.
5. Repeat steps 2 through 4 to link additional Slaves.
6. When you have finished linking all Slaves, press and release SET
button once at the Master control to exit Program Mode. Master
control LED will turn off after exiting Program Mode.
