Schneider Electric CW2LA2A Humidity Saensors Instruction Manual
SpaceLogic Sensors
Humidity Sensors – Analog and Temperature Sensors – Analog
Product Description
The SpaceLogic SLA Series of humidity and temperature sensors for living space
is a flexible multisensor platform for use with BAS controllers designed to
accept 4 to 20mA, 0 to
5Vdc or 0 to 10Vdc outputs. Housings are available in Medium matte white and
Optimum faces available in black and white. All housing types are available
with three user interface options: touchscreen, LCD with three buttons and
blank. Temperature sensors are included with all SLA Series humidity sensors

Installation
-
Position the sensor base vertically on the wall 1.35 m (4.5
ft.) above the floor with the “UP” arrow facing upward. Locate away from windows, vents and other sources of draft.
If possible, do not mount on an external wall, as this may cause inaccurate temperature readings.
-
Pull 18 or 22 AWG cable(s) through the hole in the backplate.
-
Mount the backplate onto the wall using the screws provided.
-
Connect the wires to the screw terminals. Do not over-tighten the screw

Installation (cont.)
Set the DIP switches
With sensor base fully installed, align top of cover to
mounting tabs on top of sensor base. Swing cover downward until it latches at
the bottom.
Install locking screw to secure cover in closed position.
Touchscreen Operation
Main Screen
The touchscreen user interface displays applicable sensor output values
(temperature and RH), setpoint value and menu button.
Menu Screen
The menu screen opens when pressing the Menu button on the main screen.
Integrator’s submenu, occupancy/override,
Fahrenheit/Celsius, settings and setpoint submenu (temp, RH or fan, determined
by DIP switch settings) are displayed on the menu screen
