HPC Controllers with date codes of JAN 2023 and newer include two sensor inputs. The SEN-SEN terminals from the original HPC Controllers have been split into SEN and SEN-2 to allow for two separate sensor installations (i.e., flow + rain sensor). Sensors now wire separately across the Common terminal (COM).
Front Panel (Old vs New) | Terminals | Notes |
HPC Front Panel (Pre-JAN 2023) | SEN/SEN | Currently, only compatible with a single flow/clik sensor. If the front panel (HPC-FP) is upgraded with a 2023 JAN or newer version, there is the option to use the two-sensor configuration. |
HPC Front Panel (JAN 2023 or Newer) | SEN/SEN-2/COM | Compatible with two sensors. |
