ICC2 - Sensor Wiring Update

ICC2 Controllers with manufactured date codes NOV 2023 and newer include updated sensor inputs. These changes are also denoted by a blue sticker on the back of the facepack. The SEN-SEN terminals from the original ICC2 Controllers have been replaced with two dedicated sensor inputs: 

  • Weather Sensors (Solar Sync/Clik Sensors)
  • Flow Sensors (future development)

Each sensor is now wired separately across the common terminal (C) on the ICC2 Power Module. Follow the instructions below for new ICC2 sensor wiring configurations.
