DEScRIpTION
The 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 Pentair Thermal Management 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.
