2. Navigation and parameters:
• Pressing
u
advances to the next menu item.
• If a menu item is visible, pressing either
q
or
p
displays the
current value.
• If a value is visible, pressing either
q
or
p
changes the value.
Holding
q
or
p
for a time accelerates the value change.
• If a value is visible, pressing
q
and
p
together sets the value
to the default.
• If a value is visible, pressing
u
returns to the menu item list.
SPt
Sets the relay turn-on threshold (Closed
above this level); Default:
800
SPh
Sets the relay turn-off hysteresis (Open below
this level); Default:
100
SCL
Sets the CO2 concentration scaling (
2
=
2000ppm (default);
5
= 5000ppm,
10
= 10000ppm)
ADj
Sets the CO2 concentration calibration offset up to +/-
250ppm; Default:
0
ppm
CAL
Sets the CO2 auto calibration period
OFF
Auto calibration disabled*,

60d
60 days
°FC
Selects the unit system for displayed temperature
measurements
UsR

LvL
Output Scaling (analog version only):

RUN
Close this menu with changes saved and display
parameters.
3. When setup is complete, select RUN or wait for setup mode
to time out.
*If auto calibration is disabled, sensor may experience drift. Use
in areas that are continuously occupied or with concentrated
levels of CO2 such as greenhouses should consider
dual-
channel sensor
options. Consult factory for more information.

QUICK START MENU - BACNET
IMPORTANT
: The device will not activate the BACnet interface
until the baud rate and the MS/TP MAC address are configured.
If an active RS485 network is not available, configure the device
using the
Setup Menu
(documented in the ‘AQ Series User’s
Guide’).
Access the auto configuration wizard by removing the front
cover and pressing the
q
,
u
, and
p
(all three) buttons for one
second. After the wizard activates, the display will show
CFG
.
The wizard automatically advances between each step after a
few seconds. Pressing the
u
button also advances the wizard.
bR
The baud rate value can usually be detected from
existing network activity. If no baud rate could be
detected, the display will show
??
. If necessary, use
q
and
p
to change the baud rate before advancing.
AdR
The device detects the smallest free MAC address on
the local MS/TP subnet from existing network activity.
If the installation requires a specific MAC address,
use
q
and
p
to override the detected address. If the
wizard detects that the selected MAC address
conflicts with another device, it automatically
advances to the next smallest free MAC address.
After the wizard completes, the device saves the baud rate and
MS/TP MAC address. Additionally, the device adds 665000 to
the selected MAC address and saves the resulting sum as the
device object ID. If the object ID conflicts with another device,
use
id.1
,
id.2
, and
id.3
in the
Setup Menu
to set a unique
object ID.
The BACnet interface becomes active immediately after the
wizard completes. To reconfigure the baud rate and MAC
address, use the Setup Menu or run the wizard again.
