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

Features

Installation

Remove the cover from the base at the bottom of the device.
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
Wiring for models with RH and Temperature:
- Momentary to ground.
  ** 0-10V DIP switch selectable for temperature, RH (if equipped) or fan speed (Off 0V, Auto 1.5V, Low 3.3V, Medium 6.7V or high 10V).
  Wiring for models with LCD and Temperature transmitter only (SLASLXX, SLABLXX and SLAWLXX):

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.

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
