BRIEF:                               The class starts with a thorough discussion of the system block diagram of a typical LCBS System

               showing all central equipment such as work station PC's, local and remote E-buses, the satellite processors such

               as the Constant/Variable Volume controllers, special controllers such as the Remote I/O, UV and CHC

               Controllers, system routers such as the Q7751A/B FTT to FTT and TPT to FTT routers, Q7740A/B Repeaters,

               User Interface and Configuration tool interfaces such as the Q7752A serial interface for the LONSpec PC, the

               User Interface Wall Modules such as T7770A-D and the DDWM T7780A and the E-bus FTT termination

               modules 209541B. All components of the system are discussed to a functional level.


    The controllers are not programmed via a traditional programming language such as Microcel Pascal for

    Micro/Macrocel controllers. Instead, the application program is prewritten by Honeywell engineers and the

    configurator simply configures this program via a battery of parameters. Even the point file is configured

    parametrically. The parametric database resides in the controller EEPROM. This might appear as a

    somewhat restrictive approach but in practice the parametric choices are quite elaborate and do allow an

    unusual flexibility.However, a default configuration is also available that will allow the controller to run and

    control the connected equipment without any parametric involvement. This approach leads to a much

    quicker application/engineering process once the engineer knows what choices to make to match his/her

    application. The process is quite akin to EMS programming in Excel Plus controllers. One does not write an

    EMS program for the Excel Plus Controller. Instead, one configures one by an intelligent choice of EMS

    parameters. The program is already written and is resident on the controller EPROM.

    The class covers thoroughly the basic or default configuration of the W7750A/B controller,

    XL15 Building Managers, T7770 series and other Wall modules, T7300f/Q7300H

    Commercial Thermostats and the operation of  S7760 Command Display Unit. This is done

    in order to master the engineering process as implemented in the XL 15 Engineering Application. The

    W7751 VAV controllers are the Primary focus of this class and are used to master the XL15

    Engineering Process. 


 Students also learn how to commission the controllers through the LONSpec configuration tool. Actual

physical test and checkout of the controllers is an integral part of the class.                  


Students go through the configuration process with hands-on detailed lab exercises at

least 3 times.  Students’ work is checked by bringing the configured system online via

the LONStation tool and checked for thoroughness and completeness. The engineering

solutions are also checked via the internet explorer. 


Written exercises are used throughout the class to reinforce the learning process.


OBJECTIVES:             Upon completion of the course the student will be able to:


  • Identify functionally critical components of  a connected Echelon bus
  • Understand the purpose and function of the Echelon bus
  • Install and Operate the LONSpec Engineering Tool
  • Use all features of the LONSpec Engineering System
  • Wire a VAVII controller and the XL15  for a specific application
  • Understand the purpose and function of VAVII controller Hardware/Firmware and the same for the XL15 Building Managers.
  • Perform Commissioning and Basic Configuration functions using the LONSpec Software
  • Understand functionally the purpose of all relevant controller/manager physical input and outputs and to be able to work with them.
  • Operate the S7760 Command Display Unit
  • Configure the T7300F/Q7300H Commercial Thermostat
  • Test the Configured system by bringing it online via the Lonstation software and Via the Microsoft Internet Explorer.
