Setup
System Conguration
System conguration is where altitude correction is performed and
where the operating modes are selected. Each switch can be congured
on the y at any time during normal operation without repeating the
commissioning phase.
The primary grille has control over both Altitude settings and continuous
mode. For dual grille systems, the altitude and continuous ventilation
switches are disabled on the secondary grille regardless of the switch
position.
Table 2: Selectable features
Each grille has its own occupancy and humidity sensor and will operate
independently of the other.
For instance, if both grilles have the humidity function enabled, each grille
will track its own baseline humidity and call for ventilation as needed.
Altitude Correction (default: 1,000 FT)
Locate the primary grille and remove the grille trim piece. Located on the sensor board is a dip
switch terminal. Set the rst 3 dip switches using the table below.
Set the desired operating mode(s) for each grille (Humidity, Occupancy, or Continuous Operation). For a dual grille system, congure the secondary
grille at this time. Refer to the System Conguration table below for switch positions related to each function.

Humidity
Monitors background humidity and activates ventilation
automatically when a rapid increase in humidity is
detected. Ventilation will deactivate when humidity levels
fall to within a degree of normal humidity levels. Run time
can be adjusted on a 1 to 5 scale where 1 is the shortest
run time and 5 is the longest.

Table 4: Default Values & Function Switch Positions
Commissioning mode maps out the system performance and provides a maximum airow the system can achieve.
It is important that the installation is fully completed prior to entering commissioning mode as this affects system
accuracy). Follow the steps below for initiating commissioning mode.
1. Apply power to the fan (120V).
2. Locate the primary wall switch (3 button). The ‘OFF’ button on the
fans primary wall switch will illuminate (solid) to indicate the system
has power and has established connection between the Fan, Grille,
and Wall Switch.
3. With the primary wall switch in the ‘OFF’ position, PRESS and
HOLD the AUTO and MAX buttons until both button lights illuminate
(~5 Sec). Both lights illuminating indicates the commissioning
routine has been enabled and will take approximately 2 min to
complete. A RED indicator light will energize on the Primary Grille
for the duration of the commissioning.
4. Once self commissioning is completed, the ACTION INDICATOR on
the primary grille will ash a color sequence indicating the
maximum airow the system can achieve based on the installation.

Table 5: Airow code
Example:
9 Blue ashes followed by 3 Red ashes indicate that the system
recognized it’s a Serenity Duet and the maximum airow is 195 CFM.
5. To exit COMMISSIONING MODE, Press and Hold the OFF BUTTON on
the primary wall switch until system turns off (approx. 4 seconds) and
then turn the system back on by pressing the ‘AUTO’ button.
6. To re-commission, simply repeat step 3 of the commissioning process
otherwise the system is ready to monitor the environment and operate
on the factory default airow rates and run times.
The ‘AUTO’ button on the primary wall and secondary wall
switches allow the system to determine when it needs to
operate based on the functions previously set (humidity,
occupancy or continuous).
