•ELECTRIC HEATERS wired for single point power sup- ply. These nickel chromium heater elements are pro- vided with limit and automatic reset capability to prevent operation at excessive temperatures.

•VARIABLE AIR VOLUME (VAV) - A factory-installed variable frequency drive (VFD), mounted in the Blower Access compartment, is used to control the speed of the indoor blower motor in order to maintain a constant static pressure in the supply duct. A pressure transducer and VAV control board are mounted inside the control box. The drive comes completely wired and pre-programmed from the factory.

An optional, factory-installed manual bypass switch available with factory-installed VFD can be found in the Blower Motor Access compartment. The switch can be used to either route power to the VFD for modulating control of the blower motor, to bypass the drive and oper- ate the motor at full speed, or to power the drive (and not the motor) for diagnostic purposes.

Due to space limitations, VAV is not available with any of the factory-installed BAS options described below, but is available with ‘BAS-ready’ models. Terminal blocks are provided in the control box for field wiring of the cus- tomer-installed BAS.

A ‘VFD-ready’ option provides the provisions for a cus- tomer-installed drive. The unit comes with a mounting bracket installed in the Blower Access compartment which may accommodate other vendor’s drives depend- ing on their size. In order to utilize the unit’s mounting bracket, the maximum recommended drive dimensions are as follows:

For 5-hp motor applications

10” H x 6” W x 7” D

For 7.5 thru 15-hp motor applications

13” H x 8” W x 8” D

If the customer-installed drive will not fit in the allotted space, then it will have to be mounted within a NEMA-4 enclosure for outside installation or inside the building on a perpendicular wall not subjected to excessive tempera- ture, vibration, humidity, dust, corrosive gas, explosive gas, etc.

A terminal block located in the control box is provided for field connection of the VFD controls.

•HOT GAS BYPASS - To allow for low cooling load oper- ation, a direct-acting pressure-modulating bypass control valve installed on the system #1 discharge line is used to divert high temperature, high pressure refrigerant around the TXV in order to maintain a desired minimum evapo- rator pressure. HGBP is standard on all units with VAV and optional with CV units.

•FILTER OPTIONS - Standard units are shipped with 2” throw-away filters installed. 2” pleated and 4” pleated fil- ters are offered as a factory installed option.

•CONVENIENCE OUTLET - This 110 volt outlet can be “powered” by the unit with a stepdown transformer or

262259-YTG-B-0107

you may order the unit with a “non-powered” conve- nience outlet that can be wired in the field.

•DISCONNECT SWITCH - For gas heat units and cooling units with electric heat, a HACR breaker sized to the unit is provided. For cooling only units, a switch sized to the largest electric heat available for the particular unit is provided. Factory installed option only.

•BAS - Building Automation System Controls (avail- able on two-system cooling product only).

Simplicity® INTELLI-Comfort™ CONTROL - The York® Simplicity® INTELLI-Comfort™ control is factory installed. It includes a supply air sensor, a return air sen- sor, and an outside air sensor. There are provisions for a field installed dirty filter indicator switch, an air-proving switch, an Outside Air Humidity sensor, a Return Air Humidity sensor, an Inside IAQ sensor, and an Outside Air IAQ sensor. Construction mode operation, 365-day real time clock with 7 day programming plus holiday scheduling is built-in. Two different modes of demand ventilation are achieved through the INTELLI-Comfort™ using CO2 sensors. It uses an inside CO2 sensor to per- form Demand Ventilation. It can also use an Outside CO2 sensor to perform Differential Demand Ventilation. It uses a Patented Comfort Ventilation algorithm to provide comfortable ventilation air temperature. The patented economizer-loading algorithm will protect the equipment when harsh operating conditions exist. Humidity in the occupied space or return duct can be monitored and controlled via humidity sensors and the on-board con- nection for hot gas re-heat system. It uses the INTELLI- Start™ algorithm to maximize energy savings by recov- ering the building from the Unoccupied Setpoints to the Occupied Setpoints just in time for the Occupied Time Period to begin. The Simplicity® INTELLI-Comfort™ bal- ances space temperature, ventilation air temperature, CO2 and humidity for ultimate comfort.

Simplicity® INTELLI-Comfort™ with ModLINC CON- TROL - The York® Simplicity® INTELLI-Comfort™ with ModLINC control is factory installed. It includes all the features of the INTELLI-Comfort™ control with an addi- tional control to translate communications from MOD- BUS to the BACnet MSTP protocol.

Novar® BAS CONTROL - The Novar® ETC-3 building automation system controller is factory installed. Includes supply air sensor, return air sensor, dirty filter indicator switch, and air proving switch.

JOHNSON CONTROLS BAS CONTROL - The Johnson Control YK-UNT-1126 building automation system con- troller is factory installed. Includes supply air sensor, return air sensor, dirty filter indicator switch, and air prov- ing switch.

CPC BAS CONTROL - The Computer Process Controls Model 810-3060 ARTC Advanced Rooftop building auto- mation system controller is factory installed. Includes
