Self-Contained Options

Air Volume/Temperature Control

• Zone Temperature Control

This option includes a zone sensor, microprocessor unit control module, a microprocessor compressor controller, and a unit-mounted human interface panel. The unit operates at a design airflow based on the fan and motor drive selections.

•Supply Air Temperature Control with Inlet GuideVanes

This option controls supply air temperature to the specified supply air cooling setpoint by modulating the economizer option and/or staging mechanical cooling on and off as required. Control components include a discharge air microprocessor controller, discharge air sensor, pressure sensor, and inlet guide vanes. The microprocessor controller coordinates the economizer control and the cooling stages with zone or outdoor air reset capabilities and an adjustable control band to fine-tune the control to specific applications. The inlet guide vanes (IGV) operate with the self-contained unit to control duct static pressure. The IGV option includes vanes and static pressure controls.

Inlet Guide Vanes

•Supply Air Temperature Control With Variable Frequency Drive

This option controls theVAV self- contained unit from the discharge air temperature using a factory mounted variable frequency drive (VFD). The VFD safely varies the fan motor speed to allow

the motor to meet the dynamic requirements at the motor shaft and meet the system static. Other control components include a discharge air microprocessor controller and discharge air sensor.The microprocessor controller coordinates the economizer control and the stages of cooling with discharge air temperature reset capabilities. Includes factory installed and tested variable frequency drive (VFD) to provide supply fan motor speed modulation. The VFD receives 0-10vdc signal from the unit microprocessor based upon supply static pressure and causes the drive to accelerate or decelerate as required to maintain the supply static pressure setpoint.

Supply Air Temperature Control With Variable Frequency Drive with Bypass Manual bypass control provides full nominal airflow and zone temperature control in the event of a drive failure. The VFD with bypass is factory mounted completely wired and tested. A motor overload relay and fuses are provided to properly size motor protection during both drive and bypass modes.

Waterside Economizer

The waterside economizer takes advantage of cooling tower water to either pre-cool the entering air to aid the mechanical cooling process or, provides total system cooling if the water temperature is low enough. Waterside economizing enables when the unit’s entering water temperature is below the unit’s entering mixed air temperature by a minimum of 4 F plus the economizer’s approach temperature. The approach temperature default is 4 F and is adjustable from 0 to 9 F. Waterside economizing disables when the unit’s entering water temperature is not below the unit’s entering mixed air temperature by at least the water economizer approach temperature. The economizer acts as the first stage of cooling. If the economizer is unable to maintain the supply air setpoint, the unit control module brings on compressors as required to meet the setpoint.

The waterside economizer includes a coil, modulating valves, controls, and piping with cleanouts. All components are factory installed in the unit cabinet. The coil construction is ½-inch (13mm) OD

seamless copper tubes expanded into aluminum fins. The evaporator and economizer coils share a common sloped (IAQ) drain pan. Drain pan options are either galvanized or stainless steel and insulated and internally trapped.

The waterside economizer coil options have either two or four rows with no more than 12 fins per inch. The tubes are arranged in a staggered pattern to maximize heat transfer.The coil has round copper supply and return headers with removable cleanout and vent plugs. The optional mechanically cleanable economizer has removable cast iron headers to allow easy mechanical cleaning of the tubes. The waterside working pressure is rated for 400 psig (2758 kPa).
