Image of AT-TS-14

Raychem’s AT-TS-14 thermostat provides line-sensing temperature control for frost protection cable.

The temperature set point can be checked through a window in the front face.

LED’s provide an indication when cables are energised or when the temperature sensor detects a fault (sensor break or sensor short-circuit).

If you require connection to a BMS, you will require a RAYSTAT V5.
