with VAV air handlers to control duct static pressure. Option includes vanes and static pressure controls. Airfoil supply fans with inlet vanes are an efficient way to mechanically modulate airflow.

•VAV Supply Air Temperature Control with Variable Frequency Drives w/o Bypass—Provided with all necessary controls to operate a VAV air handler 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 0-10 vdc 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 Air Temperature Control with Variable Frequency Drives and Bypass—Bypass control provides full nominal airflow in the event of drive failure.

Agency Approval

Air Handlers can be provided with UL/CSA approval.

Miscellaneous Options

•Marine Lights (Customer Powered)—A 120V master light switch is factory installed in the main unit control box for lighting control. The master switch is wired into an isolated terminal block with access for customer provided service. Marine light fixtures are supplied with 150W incandescent bulbs. Marine light fixtures are placed in the Supply Section (2), Fresh Air Section (1), Return Section (1), and Extended Casing Section (1) for units without Heat.

•Non-Fused Disconnect Switch with External Handle—External

RT-PRC031-EN

handle enables the operator to disconnect unit power with the control box door closed for safety.

•Unit Interrupt Rating—Using a non-fused circuit breaker for disconnect switch purposes a 65000 Amp rating is optionally available on 460/3/60 powered units and a 25000 Amp rating is available on 575/3/60 units. Fan motors and electric heat (if applicable) circuits are also equipped with series rated circuit breakers.

•GFI Convenience Outlet (Factory Powered)—A 15A, 115V Ground Fault Interrupter convenience outlet is factory installed. It is wired and powered from a factory mounted transformer. Unit mounted non-fused disconnect with external handle is furnished with factory powered outlet.

•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.

•Low Leak Dampers—Return air, fresh air and relief air dampers have chlorinated polyvinyl chloride gasketing to seal to a leakage rate of 10 cfm/ft^2 (AMCA Class 2) at 1.0 in w.g. pressure difference.

•Ultra Low Leak Fresh Air Dampers—Dampers have chlorinated polyvinyl chloride gasketing to seal to a leakage rate of 4 cfm/ft^2 (AMCA Class 1) at 1.0 in w.g. pressure difference.

•High Duct Temperature Thermostats—Two manual reset thermostats are provided with 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 air handler will shut down if the thermostats are tripped.

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

•High Efficiency TEFC Motors— Supply and exhaust/return fans are provided with high efficiency Totally Enclosed Fan Cooled motors.

•Belt Guards—Supply and exhaust fans can be optionally equipped with a universal size belt guard to accommodate any applicable drive configuration. The guard totally encloses the drive system and is provided with a two-piece removable front panel for servicing. Return fan guards are also available with individually sized belt guard with a single-piece removable panel for servicing.

•Airflow Paths—In addition to the traditional downflow supply and upflow return, horizontal supply and return is available. End return is also available on select units. For additional details on airflow configuration, see Table 1, p. 24 Table 2, p. 24

•Burglar Bars—A grate system is available for the supply and return air duct connection areas on non-horizontal airflow path units to minimize unwanted intrusion into duct systems.

•Generic Building Automation System (GBAS 0-5vdc) Module—
