PRO-Tect: Pipe Freeze Protection Dual-Zone Control with GFEP

Unfortunately there's no set answer for this because it depends on many factors such as the diameter of the pipes, the installation density of the heating cables, the outdoor temperature, the installation of thermal insulation sleeves, etc.

There are too many variables to provide an accurate answer. Even though this product is designed to keep pipes from freezing, it is not designed to thaw pipes. If your pipe has frozen with the heat tape installed and energized, please check the placement of the built-in thermostat and verify that the insulation has been properly installed and waterproofed.

Yes, it can be used for both application types to prevent pipes from freezing and bursting during cold weather.

Never spiral heating cable around pipes. Attach self regulating cable in straight runs at the 8 o'clock position, or if two runs are required (pipes greater than 12“ diameter) attach the cable at the 8 o'clock and the 4 o'clock positions. Please refer to the installation manual for further information.

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.

Yes you can but you will need to increase the size (AWG) of the supply lines and circuit breaker to account for the increased load.

Yes, you can use a 3-wire RTD Sensor: Platinum, Alpha = 0.00385, ITS–90,100 ohms. Once it is installed you will need to configure the controller for it by navigating to the sensor type screen and changing it to RTD. The GPT-230 will allow you to use a different sensor on each channel or you can use one sensor for both channels. It is simply a matter of how you wish to configure it.

WarmlyYours does not recommend using an extension cord for permanent installations. Pipe heat should always be plugged directly into a receptacle or hardwired to the circuit that is powering it.

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.

Do not wrap self regulating cable around the pipe in a coiled or spiral fashion, and do not use electric tape to attach it. WarmlyYours recommends attaching the cable in a straight run and to use aluminum or fiberglass tape, pipe straps, or plastic zip ties to attach the cable. Then cover the assembly with fire-resistant insulation and assure it is waterproof. Place electrical heating cable WARNING labels every 10‘, and where the label will be clearly visible.

Use plastic zip ties, aluminum or fiberglass tape, or pipe straps. Do NOT use vinyl electrical tape, masking tape or duct tape. Do NOT use metal wire or metal twist ties to attach the cable.

The GPT-230 displays a number of alarms, beside the ground fault it will also alarm for low current. If you have disconnected the load to trouble shoot a possible ground fault in the heater cable, then you probably have a Low Current Alarm and a very low default ground fault current reading.

You can tell the difference by looking closely at the display, it will tell you what the alarm is for. If you want to clear the low current alarm so you can test the controller then go into the configuration menu and disable the Low Current Alarm. You will need to do this for each channel.

Remember to re-enable the Low Current Alarms when you are done testing and ready to put the unit back into service.

The 3 dashes indicate that no ground fault current is being detected because that channel is not calling for heat.

This would indicate that you have enabled the Low Temperature Alarm and that the current temperature the sensor is sensing is below the alarm setpoint. You can change the set point, wait for the heaters to warm the sensor, or disable the alarm.
