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 five years.

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).
