TWS Series

Wall Mount with Analog Setpoints, LCD and

Thermostat Control

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.

* 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.

Tab

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.
