RAYSTAT-ECO-01
Energy-Saving Freeze Protection Controller Installation Instructions
DESCRIPTION
The nVent RAYCHEM Raystat-ECO-01 controller is used to
control heat-tracing freeze protection systems based on ambient
temperature. The controller provides a pilot-duty relay to drive an
external contactor.
The controller adjusts the power of the heating cable by
energizing the circuit for a percentage of a complete duty cycle.
For example, if the ambient temperature is halfway between
minimum ambient and 40°F (4°C), the heating cable will be
energized for 5 minutes and off for 5 minutes. The actual duty-
cycle periods and ratios vary, depending on ambient temperature.
For technical support, call nVent at (800) 545-6258.
ELECTRICAL CODES
Installation and all wiring must be in accordance with applicable
regulations. The controller must be installed by a qualified
electrician and in nonclassified areas only.
