Product overview

nVent RAYCHEM AT-TS thermostats provide temperature control in non-hazardous area.
The temperature set point can be checked through a window in the lid. LED's are providing
an indication when the relay contact is closed (Heating ON) and when the temperature
sensor is defect (sensor break or sensor short-circuit).
The temperature sensor has a length of 3 meter and can be shortened for ambient sensing
operating. Direct connection of the heating cable is possible. Connection kits need to be
ordered separately. The thermostat is available in 2 temperature ranges.

Functional description

When the temperature exceeds the setpoint, the switching contact opens and switches the
heating cable off.
When the temperature falls below the setpoint, the switching contact closes. The integrated
green LED display lights up to indicate that the heating cable is switched on. In the event of
a sensor defect, the switching contact closes. The integrated red LED display lights up to
indicate that there is a defect. In the event of power loss, the switching contact opens.
Installation
A. Pipe line sensing control
1. Attach temperature sensor to the pipe with adhesive tape. The sensor should rest
firmly against the pipe without intermediate space. The minimum distance of the
sensor from fittings and the pipe end is 1 m. The angle of the pipe between the heating
cable and the sensor should be 90-120°.
2. Mount the housing in the required position.
3. Adjust the temperature setpoint. Finish the wiring and insulation. Only operate with
insulated sensor.
4. Fill the pipes, check the operating points with a thermometer and correct if necessary.
Due to the low heat conductivity of non-metallic pipes, adjust the thermostat operating
point only when the pipe is full.
