1030: Mixing Zone Valve Configuration

David Bonnes edited this page Jan 20, 2021 · 2 revisions

1030 is for the configuration of a zone of type: Mixing Zone Vale (these use a HM80):

095  I --- --:------ --:------ 12:259810 1030 016 01C80137C9010FCA0196CB010FCC0101
074  I --- 01:145038 --:------ 01:145038 1030 016 0AC80137C9010FCA0196CB010FCC0101

Note the payload starts with a zone_idx (00-0B), and:

0A C8-0137 C9-010F CA-0196 CB-010F CC-0101

Python code is:

        param_name = {
            "C8": "max_flow_setpoint",  # 55 (0-99)
            "C9": "min_flow_setpoint",  # 13 (0-50)
            "CA": "valve_run_time",  # 150 (0-240), aka actuator_run_time
            "CB": "pump_run_time",  # 15 (0-99)
            "CC": "unknown",  # ?boolean?
        }

That is, there is an array of 5 parameters where, after ignoring the first byte (which is always 0x01):

  • C8 is Max Flow Setpoint (0-99 C, default 55 is 0x37)
  • C9 is Min Flow Setpoint (0-50 C, default 15 is 0x0F)
  • CA is Valve Run Time (10-240 secs, default 150 is 0x96)
  • CB is Pump Run Time (0-99 mins, default 15 is 0x0F)
  • CC is unknown (appears to be always 0x01)
