To install the new thermistors, Tyson

  • removed all the old insulation and tape, and disconnected the old thermistors from the wire nuts.
  • attached the new thermistors to the the wires running into the house with wire nuts.
  • covered over the junction with heat shrink and some electrical tape.
  • secured the thermistor to the pipe between the last two panels with zip ties, wires, and aluminum tape.
  • wrapped the thermistors and pipe with fiberglass insulation.
  • secured everything with more aluminum tape.
