Specifications Condensing Units

Controls

Condensing units shall be completely factory wired with necessary controls and contactor pressure lugs or terminal block for power wiring. Unit shall provide an external location for mounting a fused disconnect device.

A choice of microprocessor or electro- mechanical controls shall be available. The 24-volt electro-mechanical control circuit shall include control transformer and contactor pressure lugs for power wiring. Units shall have single point power entry as standard.

The microprocessor controls shall provide for all 24-volt control functions. The resident control algorithms shall make all heating, cooling and/or ventilating decisions in response to electronic signals from sensors measuring indoor and outdoor temperatures.The control algorithm maintains accurate temperature control, minimizes drift from set point, and provides better building comfort. A centralized microprocessor shall provide anti-short cycle timing and time delay between compressors to provide a higher level of machine protection.

Time delay timers shall be provided to help prevent compressors in dual compressor units from simultaneous start-up. An anti-short cycle timer shall be available as an optional accessory.

Zone Sensor

This field installed control shall be provided to interface with the Micro equipped units and shall be available in either manual, automatic programmable with night setback, with system malfunction lights, or remote sensor options.

Thermostat

Two stage heating and cooling operation or one stage heating and cooling shall be available for field installation in either manual or automatic changeover. Automatic programmable electronic with night setback shall also be available.

LonTalk® Communication Interface Thisfactoryorfieldinstalledoptionshall be provided to allow the unit to communi- cate as aTracer™ LCI-R device or directly withgenericLonTalkNetworkBuilding AutomationSystemControls.

LowAmbient Operation

Standard units shall start and operate to approximately 50°F when matched with air handlers and coils. Optional head pressure control accessory permits operation to 0°F.

FACTORY INSTALLED ACCESSORIES

Black Epoxy Coated Condenser Coil — This option is designed to provide corrosion protection of air cooled condenser coils for seacoast application. The black epoxy coil protection is a factory applied thermoset vinyl coating, bonded to normal aluminum fin stock. The uniform thickness of the bonded vinyl layer exhibits excellent corrosion protection in salt spray tests performed in accordance with ASTM B177.

ACCESSORIES

Vibration Isolation Packages — Shall reduce transmission of noise and vibration to building structures, equipment and adjacent spaces. Packages shall be available in either neoprene-in-shear or spring-flex types.

Hot Gas Bypass Kit — Shall be available to provide capacity modulation.

Time Delay Relay — Shall prevent compressors in dual compressor unit from coming on line simultaneously. Timer shall be 24-volt, cycle, with four minute timing period.

Anti-Short-CycleTimer — Shall prevent rapid on-off compressor cycling in light load conditions by not allowing compressor to operate for

5-7 minutes upon shutdown. Shall consist of a solid state timing device, 24- volt, cycle with either 5 or 7 minute fixed-off timing period.

Condenser Coil Guard — Metal grille with PVC coating shall be provided to alleviate coil damage.
