What type of splice should I use when joining sensor cables to system wiring?
Do not use wire nuts or connectors. Solder all wire connections, and cover them with shrink wrap tubing. Additionally, since most shrink wrap tubing is not rated as high temp or UV resistant, make sure that those connections are tucked inside UV sheathing, but outside the pipe insulation. See the SunMaxx “Sensor to Wire Connections” installation guide for the entire step-by-step process.
