Product Identification
Product Overview
The TWS analog series measures the temperature of the air inside a room. Devices are designed for use in hospital
rooms, laboratories, and other spaces that require precise environmental control. The keypad allows control of
setpoint values. The slide switch position determines the output type (amp or volt). To maintain accuracy, keep
vents clear of dust, debris, etc. The TWS is warranted for period of ve years.

Outputs Switch-selectable amp or volt
If volt is selected, the configuration menu allows selection between
0-5V or 0-10V
Physical UL 94-V-O fire retardant ABS
Temperature Accuracy ±0.5°C (±1°F)
Operating Humidity Range 0-100% RH (non-condensing)
Operating Temperature Range 10° to 35°C (50° to 95°F)
Analog Output Scaling 10° to 35°C (50° to 95°F) or 0° to 50°C (32° to 122°F), menu
selectable*
Calibration Offset Adjustable ±9.9° (C or F) in 0.1° increments
Setpoint Range
Minimum to Full Scale in 1° (C or F) increments
* If the 0° to 50°C (32° to 122°F) scaling range is selected, the device’s operating temperature range still applies.
One side of the transformer secondary is connected to the signal common, so an isolation transformer or
dedicated power supply may be required.
RTD/Thermistors in wall packages are not compensated for internal heating of the product.
EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper
surge protection (EN 61000-6-1:2007 specification requirements).

Installation Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Locate the tab at the top of the sensor housing. Using only the minimum required force, press this tab down and pull the cover
outward from the top. Set the cover aside.

2. Remove the backplate by unfastening the sensor from the bottom of the backplate and pivoting the sensor outward.
3. Punch out wire opening in the backplate.
4. Position the backplate vertically on the wall, 4 ½ feet (1.4 m) above the oor. Locate away from windows, vents, and other
sources of draft. If possible, do not mount on an external wall, as this might cause inaccurate temperature readings.
