DESCRIPTIONThe 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.
