Options

•VAV Supply AirTemperature control with inlet guide vanes — Provided with all the necessary controls to control/ operate a VAV rooftop from the discharge air temperature, including a discharge air microprocessor controller, a discharge air sensor, pressure sensor and inlet guide vanes. The microprocessor controller coordinates the economizer control and the stages of cooling with zone or outdoor air reset capabilities and an adjustable control band to fine-tune the control to specific applications.The inlet guide vanes are used with VAV rooftops to control duct static pressure. Option includes vanes and static pressure controls. Forward-curved fans with inlet vanes are the most efficient way to mechanically modulate airflow.

•Exhaust Fan Variable Frequency Drives w/o Bypass (with Statitrac Only) — Provided with all the necessary controls to control/maintain building space pressure through a CV orVAV rooftop.The Variable Frequency Drive (VFD) modulates the speed of the exhaust fan motor in response to building pressure. A differential pressure control system, called Statitrac, uses a differential pressure transducer to compare indoor building pressure to atmospheric pressure.The VFD receives a 0-10vdc signal from the unit microprocessor based upon the space static pressure and causes the drive to accelerate or decelerate as required to maintain the space pressure within the deadband.

•Exhaust Fan Variable Frequency Drives and Bypass (with Statitrac Only) — Bypass control provides full nominal airflow in the event of drive failure.

•VAV Supply AirTemperature Control withVariable Frequency Drives w/o Bypass — Provided with all necessary controls to operate a VAV rooftop from the discharge air temperature, including 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 drives (VFD) to provide supply fan motor speed modulation.

VFD receives 0-10vdc 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.

•VAV Supply AirTemperature Control with Variable Frequency Drives and Bypass — Bypass control provides full nominal airflow in the event of drive failure.

Ambient Control

•Low Ambient Dampers are provided on condenser fan to allow the unit to operate down to 0 F. (20-75 tons only)

Agency Approval

•Rooftops can be provided with either Underwriter’s Laboratories (UL) or Canadian Standards Association (CSA) approval.

Miscellaneous Options

•Non-Fused Disconnect Switch with External Handle — External handle enables the operator to disconnect unit power with the control box door closed for safety.

•Hot Gas Bypass — Valves, piping and controls are all included to allow operation at low airflow, avoiding coil frosting and damage to compressor. When suction pressure falls below valve adjustable setpoint, the valves modulate hot gas to the inlet of the evaporator.

•Economizer Control with Comparative Enthalpy — used with the fresh air economizer, two enthalpy sensors are provided to compare total heat content of the indoor air and outdoor air to determine the most efficient air source when economizing.

•Economizer Control with Reference Enthalpy — used with the fresh air economizer, an outdoor enthalpy sensor is provided to compare the total heat content of outdoor air to a locally adjustable setpoint.The setpoint is programmed at the human interface, or remote human interface, to determine if the outdoor enthalpy condition is suitable for economizer operation.

•Economizer Control with Dry Bulb — used with the fresh air economizer, an outdoor temperature sensor is included for comparing the outdoor

dry bulb temperature to a locally adjustable temperature setpoint.The setpoint is programmed either at the human interface, or remote human interface, to determine if outdoor air temperature is suitable for economizer operation.

•Ultra Low Leak Fresh Air Dampers — Dampers have chlorinated polyvinyl chloride gasketing to seal to a leakage rate of 1 percent of nominal airflow at one-inch W.C. static pressure.

•High DuctTemperatureThermostats — Two manual reset thermostats, one located in the discharge section of the unit set at 240 F and the other in the return section set at 135 F.The rooftop will shut down if the thermostats are tripped.

•High Capacity Evaporator Coil — Additional rows of coil and enhanced evaporator tube surfaces provide increased capacity compared to standard coils.

•Copper Fins On Condenser Coil — Copper fins offer extra corrosion resistance as compared to standard aluminum fins.

•Generic Building Automation System (GBAS) Module — Provided for those cases where the customer uses a nonTracer building management systems.The GBAS module provides a binary input for Demand Limiting, four

(4) analog inputs for setpoint adjustment and five (5) relay outputs for diagnostic reporting. Inputs can use a potentiometer or 0-5 vdc signal.

•High Efficiency Motors — Supply and exhaust fans are provided with high efficiency motors.

•Remote Human Interface Panel (RHI)

— Remote Human Interface Panel can perform all the same functions as unit mounted Human Interface Panel, except for the Service Mode. Up to 4 rooftop units can be monitored and controlled with a single Remote Human Interface Panel.This panel uses the same attractive enclosure as our Tracker® building control panel.With features such as a 2 line X 40 character clear English display, a red LED light to indicate an alarm condition (alarm also shown on the two line display), a simple 16 key keypad that is used in conjunction with the display, to prompt
