ICC2 Controllers with manufactured date codes MAY 2024 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
Each sensor is now wired separately across the common terminal (C) on the ICC2 Power Module. For new ICC2 sensor wiring configurations, follow the instructions below.

IMPORTANT: Remove the red jumper. | |||
