Pipe Freeze Pro’s integrated thermostat means that the cable can completely cut off power to the Heat Tape and save electricity beyond the functions of self-regulating heat tape. It’s a great feature that makes Pipe Freeze Pro unique among our products. (On Heat Tape Pro, this can be achieved with sensors and thermostats)

Does the thermostat/sensor need to be touching the Pipe?

Depending on your situation, you may want the integrated thermostats sensor to be directly in contact with the pipe it is protecting. In other situations you may want it to be exposed to the ambient temperature around the pipe. You’re going to want to do which ever is colder.

In situations where the ambient air is cooling the pipe to the point of freezing, you can leave the sensor exposed to the air. In situations where the pipe is conducting cold from another source, you’ll want to touch the sensor directly to the pipe. The sensor should not touch an area of the pipe that is measurably warmer than the specific area you want to protect.

Should the thermostat sensor be under the insulated wrap or foam?

No. If you are touching the thermostat sensor to the pipe, the thermal conductivity of the pipe will be good enough. you don’t need to enclose the sensor with the pipe. If you are using the sensor to detect the ambient air temperature around the pipe, you’ll actually be doing a disservice to the effectiveness of your heat tape by covering the sensor.
