Mechanical Specifications
multiple V-belt sized for 130% of nominal motor horsepower. All drive components shall be
accessible without using scaffolds or ladders.
Supply fan motors are either open drip-proof or totally enclosed fan cooled.The motors shall have
a standard NEMAT-frame and a service factor of 1.15. All 60Hz motors meet the Energy
Independence and Security Act of 2007 (EISA).
The entire fan assembly including drive components shall be mounted on a common base.The fan
base shall be isolated inside the unit on rubber-in-shear isolators.The entire assembly shall be
statically and dynamically balanced at the factory.
Filters
Two-inch throwaway fiberglass filters shall be provided for installation during construction.
IntelliPak Unit Controls - DDC
Microprocessor controls shall be provided to control all unit functions.The control system shall be
suitable to control CV or VAV applications.The controls shall be factory-installed and mounted in
the main control panel. All factory-installed controls shall be fully commissioned (run tested) at the
factory. The unit shall have a human interface panel with 16-key keypad, a two line, 40 character
clear language (English, French, Spanish) display as standard to provide the operator with full
adjustment and display of control data functions.The unit controls shall be used as a stand-alone
controller or as part of a building management system involving multiple units.
1
The unit shall be equipped with a complete microprocessor control system.This system shall
consist of temperature and pressure (thermistor and static pressure transducer) sensors, printed
circuit boards (modules) and a unit mounted human interface panel. Modules (boards) shall be
individually replaceable for service ease. All microprocessors, boards, and sensors shall be factory
mounted, wired and tested.
The microprocessor boards shall be stand-alone DDC controls not dependent on communications
with an on-site PC or building management network.The microprocessors shall be equipped with
on-board diagnostics, indicating that all hardware, software and interconnecting wiring are in
proper operating condition.The modules (boards) shall be protected to prevent RFI and voltage
transients from affecting the board’s circuits. All field wiring shall be terminated at separate, clearly
marked terminal strip. Direct field wiring to the I/O boards is not acceptable.
The microprocessor’s memory shall be non-volatile EEPROM type requiring no battery or
capacitive backup, while maintaining all data.
2
Zone sensors shall be available in several combinations with selectable features depending on
sensor.
3
The human interface panel’s keypad display character format shall be 40 characters x two lines.The
character font shall be 5 x 7 dot matrix plus cursor.The display shall be Supertwist Liquid Crystal
Display (LCD) with blue characters on a gray/green background that provides high visibility and
interface ease.The display format shall be in clear language (English, French, Spanish).
4
The keypad shall be equipped with 16 individual touch sensitive membrane key switches.The
switches shall be divided into four separate sections and password-protected to prevent tampering
by unauthorized personnel.The six main menus shall be STATUS, SETPOINTS, DIAGNOSTICS,
SETUP, CONFIGURATION, and SERVICE MODE.
