The selection options for Chillers are:

Number of Chillers: This option describes the number of chillers in the system.

  • One

  • Two

  • Three

  • Four

  • Five

  • Six

  • Seven

  • Eight

Select Type of Sequencing: This option describes the method of sequencing or staging the chillers in the system.

  • Return Water Temp Differential: This option sequences chillers to maintain a return water differential.

  • Chiller Load: This option sequences chillers based on the load of each chiller.

    • % Full Load Amps: This option provides control based on a percent of full load amperes.

    • Actual Amps: This option provides control based on actual amperes.

  • Decouple Loop Flow: This option sequences chillers using a decouple loop flow.

    • Bi-directional Flow Sensor: This option provides a flow meter that reads and outputs a positive or negative flow.

    • Bi-directional Flow Sensor with BI input: This option provides a flow meter that always outputs a positive value, but also has a BI that indicates a positive or negative flow.

    • Calculate Decouple Flow: This option is available when there are two flow meters that are used to calculate the decouple flow.

  • Building Load: This option sequences chillers to meet building load.

    • BTU Meter AI: This option measures the building load with a BTU meter through a single AI.

    • Calculate Building Load: This option determines building load using two temperatures and a flow meter.

Chiller Rotation (Runtime): This option automatically changes chiller staging order based on runtime (equal runtime rotation strategy).

Chiller Status: This option monitors the status of each chiller.

Chiller Maintenance Switch: This option generates network inputs used to remove a chiller from service.

  • Maintenance Switch (BI): This option generates a binary input used to remove a chiller from service.

Chill Water Pumps: This option provides control for any chill water pumps.

  • Dedicated Primary CHW Pumps: This option provides control if each chiller has one dedicated CHW pump.

    • Pump Status: This option monitors the status of the pump.

      • Loss of Status Strategy

        • Automatic Restart

        • Manual Restart

          • Unit Reset Switch (BI)

    • Alarm Management

      • Motor Overload Tripped

        • Automatic Restart

        • Manual Restart

          • Unit Reset Switch (BI)

      • Belt Alarm

        • Automatic Restart

        • Manual Restart

          • Unit Reset Switch (BI)

    • Blocking Protection: This option provides monitoring of the command to a motor (typically a pump). If the command is off for an extended period of time (for example, 7 days), the motor starts for a short time (for example, 30 seconds). This feature prevents blocking (that is, it prevents the motor from seizing up).

    • Bypass Valve with Diff Pressure Sensor: This option allows a bypass valve to control differential pressure.

  • Parallel Primary CHW Pumps: This option provides control when CHW pumps are piped in a parallel fashion (any pump may work with any chiller).

    • One Pump

    • Two Pumps

    • Three Pumps

    • Four Pumps

    • Five Pumps

    • Six Pumps

    • Seven Pumps

    • Eight Pumps

    • Bypass Valve with Diff Pressure Sensor: This option allows a bypass valve to control differential pressure.

  • CHW Pump Speed:
    • Single Speed Pump
    • Variable Speed Pump
