The PT-DUAL is a control that can be used with WarmlyYours PRO-Tect: Pipe Freeze Protection Self-Regulating Heating Cable for most commercial (non-hazardous) and residential applications that require 2 independent heater-control circuits. This control can be used for pipe freeze protection or process heating applications. Because this control comes with 2 temperature sensors and 2 built-in relays, it can independently or jointly control 2 resistive loads of up to 30-amps apiece.  Another added benefit of this control is that the integrated Ground Fault Equipment Protection (GFEP) in each of the heating circuits eliminates the need for GFEP protection in a circuit panel, which can significantly save on cost. The temperature set-points for the control are adjustable from −99.9 °F to 999 °F (note: please confirm the separate temperature rating of the heating element/s you use with the control) though the included sensors have an operating range of −40 °F to 230 °F. There are 2 temperature sensor inputs and the heating circuits can operate independently or from 1 sensor.

Can pipe heat be installed in walls?

No. Only install pipe heat (heat trace cable) in accessible locations. Do not install this self regulating cable in walls or any place where the cable is hidden. Do not run it through walls, ceilings, or floors. The cable must be installed 10“ away from combustible surfaces, such as wood, and it should not be embedded in insulation or roofing material.

What is the difference between WarmlyYours Ice Shield and WarmlyYours Pro-Tect self regulating cable?

Ice Shield is 120V or 240V and outputs 5W/ft, and is designed for roof and gutter deicing.
PRO-Tect is 120V or 240V and outputs 5W/ft, 8W/ft, or 10W/ft, and is designed for pipe freeze protection.

Can I plug self regulating cable into an electrical outlet?

WarmlyYours offers a conversion kit (SR-PLUG-KIT) to enable a plug-in requirement. This kit includes ground fault equipment protection (GFEP). The receptacle must be 120V, grounded, and approved for wet locations if located outside. The self regulating cable must not exceed 140‘ in length.
