These selections provide the logic to control a Cooling coil.

The selection options for Coils (Cooling - Cold Deck) are:

Cooling - Cold Deck

Condensate Alarm: This option adds a binary input for a condensate sensor that stops the cooling when activated.
  • Shutdown on Alarm: This option places the system in shutdown mode when the condensate alarm is active.

Cooling Lockout from Outdoor Air

DX Cooling

  • Device Rotation

  • First Stage Modulated: When you check this, you can select up to four stages of cooling.

  • Number of Stages

    • One Stage

    • Two Stages

    • Three Stages

    • Four Stages

    • Five Stages

    • Six Stages

    • Seven Stages

    • Eight Stages

    You can select up to 8 stages of cooling if the first stage is not modulated.

Chilled Water

  • Proportional Actuator

  • Incremental Actuator

  • Two Position Actuator

    • Face and Bypass Damper

      • Proportional Actuator

      • Incremental Actuator

  • Entering Water Temperature

  • Leaving Water Temperature

  • Coil Pump

    • Pressure/Flow Boost

    • Low Temperature Circulation

    • Both Pressure/Flow & Low Temp Circulation: This option combines the existing two sequences to start the pump either when the valve command exceeds zero or when the outdoor air temperature drops below the setpoint.
    • Dual Pumps: This option adds a second coil pump to operate in a duty/standby configuration.
      • Rotate to Balance Runtime: When you select this option with Dual Pumps, the application automatically shifts the lead to the pump with the lowest operating hours.

    • Pump Status

      • Loss of Status Strategy

        • Automatic Restart

        • Manual Restart

          • Unit Reset Switch (BI)

    • Alarm Management

      • Lockout Switch

      • Motor Overload Tripped

        • 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).

  • Shutdown Strategy

    • Off

    • Protect Coil Based on Outdoor Air Temperature

    • User Defined Position

  • Loss of Airflow Strategy

    • Off

    • Remain in Control

    • Protect Coil Based on Outdoor Air Temperature

    • User Defined Position

  • Unreliable Sensor Operation

    • Off

    • Hold

    • Protect Coil Based on Outdoor Air Temperature

    • User Defined Position

The Loss of Airflow Strategy options are available only when the Automatic Restart option for the Supply Fan Status Loss of Airflow Strategy is selected.
