DESCRIPTION
The nVent RAYCHEM ECW-GF-DP is a remote display panel only
for the RAYCHEM ECW-GF electronic controller. The ECW-GF-DP
allows remote monitoring of the heating cable system operation.
The display has LED indicators which signal communication loss
to the controller, high/low temperature alarm, and temperature
sensor failure. The display also has buttons to test and reset the
ground-fault sensor. The display may be located up to 328 feet
(100 m) from the ECW-GF controller.
The ECW-GF-DP remote display panel must be installed in
conjunction with the ECW-GF controller. Refer to the ECW-GF
installation instructions (H58339) for further details.
For technical support, call nVent at (800) 545-6258.
TOOLS REQUIRED
• Large slotted screwdriver • Needle nose pliers
• Small slotted screwdriver • Wire strippers

To test the ground-fault circuitry, press and hold
the Test button, if the circuit passes, the Amber
LED will blink rapidly.
System Alarm
If the Red and Amber LEDs are blinking
alternately, the heating cable system is in
alarm. (Temperature sensor failure or high/low
temperature alarm.) Check the ECW-GF controller
for the displayed error.
