Summary of Contents for EVAPCO Eco-Air

  • Page 1 EVAPCO Controller Users Manual For eco-Air Air Cooled and Adiabatic Fluid Coolers and Condensers ™ For EVAPCO Authorized Parts and Service, Contact Your Local EVAPCO Representative or the Local Mr. GoodTower Service Provider ® EV PCO, Inc. — World Headquarters & Research/Development Center EV PCO, Inc.

  • Page 2: Table Of Contents

    EVAPCO Controller ........

  • Page 3: Introduction

    Warning: Do not attempt to service or enter the eco-Air unit even if the unit status is indicated as being off. Unless power is completely removed from the eco-Air unit, it may be possible for the eco-Air unit to start at any time without notice.

  • Page 4: Panel Installation Considerations

    When the EVAPCO Controller does not ship factory mounted on the eco-Air unit, the EVAPCO Controller should be placed in close proximity to the eco-Air unit to reduce the wire lengths required. If the EVAPCO Controller is within sight of or mounted on the eco- Air unit, the EVAPCO Controller may be used as the main electrical disconnect for the eco-Air unit.
  • Page 5 When the EVAPCO Controller ships factory mounted to the eco-Air unit, the supplied temperature or pressure sensor must be wired to the junction box location on the connection end of the eco-Air unit (Figure 3). If the EVAPCO Controller does not ship factory mounted, the supplied temperature or pressure sensor must be wired to the EVAPCO Controller.

  • Page 6: Wiring Considerations

    All wiring in and out of the EVAPCO Controller should be with copper conductors and wire lengths must be kept as short as possible. Consult the detailed wiring diagram for field wiring connections of each device. Applicable electrical codes for the location should be followed during the sizing and installation of the field wiring.

  • Page 7: Screen Navigation

    Navigating the Display The operator interface contains a LED display and six buttons that allow the user to navigate the various screens as well as view and modify several setpoints that affect the operation of the eco-Air unit. Figure 4 The operator interface of the EVAPCO Controller.

  • Page 9: Navigating The Scheduler

    Navigating the Scheduler Several functions of the EVAPCO Controller are able to be scheduled to operate during certain periods of the year or at certain times of the day. In this example, consider a noise restriction from 8:00pm to 5:30am starting Sunday night and ending Friday morning.
  • Page 10 Controller User Manual Each block represents a half hour period of time. First, press the ENT button four times until the first block is highlighted by the cursor. Note that this first block represents 12:00am to 12:30am. Figure 10 The 12:00am to 12:30am block is selected. Press the UP or DOWN button to enable the Quiet Mode during the selected period of time.
  • Page 11 Controller User Manual This schedule for Monday now may be copied to the other days of the week. Press the ENT button to place the cursor after the copy to text shown on the display. Figure 13 The day to copy to the current schedule to is highlighted by the cursor. Use the UP button to change the copy to date to Tuesday and press the ENT button.
  • Page 12 Controller User Manual Repeat the steps above until the desired scheduled is set. Below is what the schedule of each day of the week should be for this example. Figure 16 The Quiet Mode weekly schedule for the presented example.

  • Page 13: Operator Interface Screens

    (see the Service Screens section for more information). Figure 18 The Standby Screen. If the eco-Air unit is equipped with a pre-cooling system, the status of the solenoid valve is shown at the bottom of the screen as shown in Figure 18.
  • Page 14 Alarms Screen. Figure 19 Standby Screen with an active alarm. When the eco-Air unit is equipped with EC fan motors, the status and current speed of the fan motors may be viewed by pressing the DOWN button. Figure 20 The left screen displays the status of the fan motors.
  • Page 15 When the eco-Air unit is equipped with a pre-cooling system, several additional status screens indicate the various timers associated with the control of the pre-cooling system. Figure 21 though Figure 24 will not be displayed unless the eco-Air unit is equipped with a pre-cooling system.

  • Page 16: Alarms Screen

    When the pre-cooling system contains multiple stages or solenoid valves, the solenoid or pre-cooling section that enables first will change after all stages are switched off. For example, if the eco-Air unit contains two stages, the first time the pre-cooling system activates, stage one will be activated first followed by stage two.

  • Page 17: Main Menu Screen

    The On/Off Unit Screen shows and allows the operator to set the current operational status of the eco-Air unit. When the eco-Air unit is not controlled via an external source (i.e. BAS), the On/Off Unit Screen is the only way to disable the eco-Air unit without removing power.

  • Page 18: View Setpoints Screen

    One of the screens that allows viewing, but not editing of setpoints and options. Clock/Scheduler Screens The Clock/Scheduler Screens allows the internal clock of the EVAPCO Controller to be set as well as the scheduling of several routines. If enabled, the following routines may be programmed during certain periods of certain days:...

  • Page 20: Input/Output Screens

    Input/Output Screens Figure 34 displays the current status of all digital inputs, digital outputs, analog inputs, and analog outputs of the EVAPCO Controller. This screen is primarily used for troubleshooting and start-up purposes to determine if the correct signals are being sent to and from the EVAPCO Controller.
