OPERATION

The AQW series design allows customization for a sensor that

meets project requirements for monitoring temperature, CO2

and relative humidity. The product can be ordered as stand

alone temperature, CO2/Temperature, RH/Temperature or all-

in-one CO2/RH/Temperature with a 0-5/10V analog or BACnet

RS485 output. This installation manual applies to the Analog

Version AQW sensor with 0-5/10V output.

To verify the features see the ‘Product Identication’ section of

the installation manual. All versions come with temperature as

a standard output. For CO2 and RH sensing, the option must

be added at the factory.

INSTALLATION

1. IMPORTANT! Locate the device in an area away from

ventilation sources and heat generating equipment and

appliances. The device should be mounted at light switch

height in a vertical orientation. Use insulating material behind

the device to ensure reading accuracy.

NOTE: Do not install the device in multi-gang electrical boxes

with line voltage or other electrical devices.

2. Install backplate to wall or j-box using screws provided.

3. Wire according to installation requirements.

4. Apply power.

5a. Congure the device with ‘Quick Start Menu’ below.

-or-

5b. Congure the device using the extended setup menu (See

‘Menu Options’on page 3 for instructions to access ‘AQ Series

User’s Guide’ online).

QUICK START MENU

1. Press and hold qand u(the left and center buttons) for 1 second to enter the Quick Start Menu that is adjustable using the

LCD. Screen will display SPt when the menu has been activated.

2. Navigation and parameters:

• Pressing uadvances to the next menu item.

• If a menu item is visible, pressing either qor pdisplays the current value.

• If a value is visible, pressing either qor pchanges the value. Holding qor pfor a time accelerates the value change.

• If a value is visible, pressing qand ptogether sets the value to the default.

• If a value is visible, pressing ureturns to the menu item list.

SPt Sets the relay turn-on threshold (Closed above this level); Default: 800

 SPh Sets the relay turn-o hysteresis (Open below this level); Default: 100

 SCL Sets the CO2 concentration scaling (2= 2000ppm (default); 5= 5000ppm)

 UN Close this menu with changes saved and display parameters.

3. When setup is complete, select RUN or wait for setup mode to time out.

VISUAL INDICATORS

Each measurement should display in turn.

If a measurement does not appear, the respective sensor is

damaged, has been removed from the device, or has been

selected not to appear through the Users Menu (See ‘AQ Series

User’s Guide’).

HOME SCREEN

By default, the device displays one measurement at a time,

rotating between measurements every 10 seconds if multiple

sensor options are installed.

To change which measurements are displayed on the LCD,

access the Users Menu (See ‘AQ Series User’s Guide’).

TROUBLESHOOTING

Symptom Solution

No output Check wiring. Ensure power supply

meets requirements.

Reading error

Verify unit is located away from

hot/cold sources.

Verify control panel software is

congured correctly.

Verify accuracy of test instrument.

Install insulation behind sensor to

prevent air ow from inside wall.

INSTALLING MENU BUTTON COVER

The AQW installation kit oers two cover options:

If the anti-tamper cover is used, discard the buttons.

When using the LCD bezel, place the two buttons provided in

locations 1 and 2 with the rounded end up/outward.

Snap on the LCD bezel once the buttons have been placed in

positions 1 and 2.
