SECTION 1 - INTRODUCTION

This Quick Start-up Guide indicates required field 

wiring, miscellaneous connections, and minimum pro-

gramming to provide proper unit operation. This guide 

does not include required basic installation practices 

discussed in the YSWU/YSWD with IPU control In-

stallation, Operation, and Maintenance manual (Form 

145.05-NOM3). The IOM should be reviewed to en-

sure all proper procedures and safety precautions are 

followed when installing this equipment.
In addition, any system alarms indicated by the User In-

terface should be diagnosed as referenced in the Instal-

lation, Operation, and Maintenance manual - 

refer to the 

Fault Description Table, located in the Service section of  

the IOM. 

This Quick Start-up Guide is indexed according to unit 

type and options. Units are categorized as either:

•  Constant Volume by type of control (zone sensor, 

or communicated zone sensor),

•  Variable Air Volume (VAV) by type of supply air 

reset (hard wired, outdoor air temperature, return 

air temperature, or supply fan speed), or

•   FlexSys*. 

SECTION 1 - INTRODUCTION

Refer to applicable section for required field wiring, 

miscellaneous connections, and programming.

References to “Programming” indicates the setpoints 

that should be programmed/verified, under the respec-

tive key on the User Interface keypad (SETPOINT, 

PROGRAM OPTIONS, DATE/TIME, and SCHED-

ULE keys).
Unit options should be programmed based on the unit 

configuration as supplied by the factory.

Refer to Appendix 1 for Installation and Programming 

information before using this Quick Start-up Guide.

Appendix 2 outlines the sequence of operation of the 

Factory Run Test feature of the control. The unit soft-

ware, as shipped from the factory, contains the Fac-

tory Run Test program. The Factory Run Test feature 

is used by the factory to verify proper operation of the 

unit. However, this feature can also be used in the field 

during start-up. By running the program you can easily 

determine that all the key electrical components of the 

unit are working properly. 

See Appendix 2 for direc-

tions on how to turn on the Factory Run Test feature 

as well as a description of the operation of the test 

sequence.

* FlexSys VAV is YORK’s VAV Underfloor Air Unit.
