Introduction

EVAPCO Controller

Congratulations on the purchase of your eco-Air unit with the EVAPCO Controller. The EVAPCO Controller will ensure that your

eco-Air unit is operating in the most efficient manner possible while using minimal resources. Along with proper eco-Air unit

maintenance, the EVAPCO Controller will ensure that your eco-Air unit provide years of service at peak efficiency.

The EVAPCO Controller serves as a single connection point for the eco-Air unit and contains all of the protection and logic devices

required to run the eco-Air unit in the most efficient manner possible.

n order to reduce downtime, Evapco recommends keeping a stock of spare fuses. Consult the wiring diagram for the quantity,

type, and fuse size required. Contact your local EVAPCO representative for replacement or spare parts.

This bulletin includes a description of the screens and parameters that are available through the display located on the front of the

EVAPCO Controller. Also included in this bulletin are the functions of the EVAPCO Controller. Please note that the screens

displayed on your EVAPCO Controller display may vary slightly from the images shown in this document.

Become familiar with the EVAPCO Controller by thoroughly reading and understanding the content of this bulletin. A detailed wiring

diagram can be found in the data pocket inside of the EVAPCO Controller.

f you should require any additional information about the operation or maintenance of this equipment, contact your local EVAPCO

representative. You may also visit www.evapco.com for more information.

In tallation and Wiring

Safety

Qualified personnel should use proper care, procedures, and tools when operating, maintaining, or repairing this equipment or any

other connected equipment in order to prevent personal injury and/or property damage. The warnings listed below are to be used

as guidelines only.

Warning: EVAPCO eco-Air units should never be operated without fan screens and access doors properly secured and

in place.

Warning: Avoid working on electrical circuits while they are live. Proper lock-out/tag-out and all applicable safety

practices must be followed prior to servicing any equipment.

Warning: Before opening the panel door, allow sufficient time for VFD’s to discharge after removing power. VFD’s contain

capacitive circuits which maintain a charge even after power is removed.

Warning: The three position selector switch is not intended to replace or act as a disconnect to disable the EVAPCO

eco-Air unit and/or de-energize the EVAPCO Controller. Be sure to follow lock-out/tag-out and all applicable

electrical safety practices before servicing any equipment.

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.

Be sure to follow lock-out/tag-out and all applicable electrical safety practices before servicing any equipment.

Controller User Manual

The following safety issues need to be addressed by those responsible for the installation, maintenance, and repair of the EVAPCO

Controller:

•Access to the control panel (including the disconnect switch(es)).

• Sizing and protection of electrical circuits feeding the control panel(s) and branch circuits feeding the controlled equipment.

• Proper grounding of electrical circuits.

• Qualification of persons who will install, maintain, and service the electrical equipment.

Panel In tallation Con ideration

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. f 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. Otherwise, separate electrical

disconnects may be required. Consult applicable electrical codes to make this determination. Avoid mounting the EVAPCO

Controller with a southern exposure. This will minimize the amount of solar heat gain the system will experience and will make it

easier to view the operator interface.

Temperature/Pre ure Sen or In tallation

EVAPCO eco-Air fluid coolers are supplied with a thermowell (1/4” G threads) and a NTC temperature sensor. The thermowell and

temperature sensor should be installed in the common return pipework of the eco-Air fluid cooler unit. Thermowells must be

installed in the horizontal sections of the coil piping. A small amount of thermal paste should be added to the thermowell before the

NTC sensor is inserted to ensure a more accurate fluid temperature measurement.

Figure 1

The suggested temperature sensor location for fluid coolers. Piping shown by dashed lines provided and installed by others.

TEMPERATURE SENSOR TEMPERATURE SENSOR

EVAPCO eco-Air condensers are supplied with a pressure transducer (7/16”-20 UNF threads). The pressure transducer should be

located in the common compressor hot gas discharge pipework. t is recommended that a shut-off valve be located between the

pipework and the pressure transducer to allow the transducer to be more easily replaced should it become damaged.

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). f the EVAPCO Controller does not ship

factory mounted, the supplied temperature or pressure sensor must be wired to the EVAPCO Controller. Consult the supplied

wiring diagram for a determination if the junction box is supplied.

Each EVAPCO Controller is supplied with one ambient air sensor that is located on the bottom of the Controller enclosure. Should

the EVAPCO Controller be placed in a location where the ambient temperature (i.e. indoors) is not indicative of the ambient

temperature of the eco-Air unit, the ambient temperature sensor must be relocated to a more suitable location and the resulting

opening in the enclosure must be sealed with a Type 4 plug.

PRESSURE SENSOR PRESSURE SENSOR

Controller User Manual

Wiring Con ideration

Consult the supplied wiring diagram for detailed wiring information. All field wiring is indicated by dashed lines on the wiring

diagram.

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. All fittings attached to the EVAPCO Controller

must be Type 4. All wiring must be through the bottom of the EVAPCO Controller. Top entry into the EVAPCO Controller is

not permitted. Any damage caused to any component within or connected to the EVAPCO Controller due to a top entry

connection is not warrantable!

For wiring the EVAPCO Controller to each NEMA fan motor, Belden®VFD cable 295XX (XX denotes gauge) or equivalent should

be used. The shield of the VFD cable needs to be bonded to ground at both ends of the cable.

While the EVAPCO Controller does provide provisions for connection to a BAS, this connection is not required for the EVAPCO

Controller to operate.

Operation and Servicing

On eco-Air units equipped with NEMA fan motor(s), the EVAPCO Controller contains a three position selector switch (Bypass-Off-

Auto) located behind the HM door. The operation of each position is as follows:

Auto: The Auto position allows the EVAPCO Controller to operate the eco-Air unit based on the logic programmed into the

Controller. Note that the unit must be switched on before the eco-Air unit will begin to operate. Please see the On/Off Unit

Screen section of this document for more information.

Off: n the Off position, the EVAPCO Controller will be powered; however, output commands will not be sent to any of the

attached equipment. This position is used for programming the VFD.

Bypass: n the Bypass position, the logic program is bypassed which allows the fan motor(s) to energize independent of

sensor temperature or setpoints. Power is routed around the VFD and thus the fan motor(s) will operate at full power, across-

the-line. The VFD will still be energized when the selector switch is in the Bypass position.

The door protecting the HM must be shut unless an operator is using the HM interface. This will protect the HM interface from

contamination and increase the life of the HM .

The EVAPCO Controller is supplied with air filters that must be inspected every 90 days. Depending on the installation

environment, more frequent inspection and/or replacement may be required. A dirty filter can cause the internal panel temperature

to increase and may cause component failure. Permanently removing the filter will allow dirt and particulates to enter the enclosure

and may cause premature failure.

Please consult the proper Operation and Maintenance nstructions for start-up and maintenance guides for the eco-Air unit

attached to the EVAPCO Controller.
