1. Enter program control instructionCOMPUTE SYSTEMS ..to instruct the processor to perform calculations.m. If the PLANT and ECONOMICS programs are not to be run, enter theprogram control instructionSTOPn. The User Worksheets with each command have been provided to helporganize the data-input effort. They provide a space for theentry of a label or a value for each command word, keyword, andcode-word.It is suggested that the applicable worksheets be reproduced byphotocopy in the requisite numbers (i.e., one copy for each lONE,each SYSTEM, etc.). The worksheets can be filled out in anyconvenient order, but it is recommended that they be arranged inthe sequence described in paragraphs a thru m above, beforestarting data input.WARNINGThe proper specification of SCHEDULEs in the SYSTEMS simulator is asimportant, if not more important, than the proper specification of SCHEDULEsin the LOADS simulator. In SYSTEMS, these SCHEDULEs turn the HVAC equipmenton and off, reset temperatures, establish flow rates, etc. These SCHEDULEsshould be thought of as "system controls". They control the HVAC system asmuch as do economizer control strategies and fan control strategies. The programdoes not automatically control, nor optimize the operation of, the HVACequipment. The user must control the equipment via the input for his SCHEDULEsor be aware of what the program is doing if a SCHEDULE is allowed to default.The improper specification of SCHEDULEs can easily double the energy consumptionof the simulated building.8. SOL Input Instruction LimitationsThe maximum number of each type of SOL instruction that the program canaccept in a single run is shown in Table IV.1. A building that cannot be specified,without exceeding these limits, should be divided in the most convenientmanner and modeled as two separate buildings, or the user should inquireconcerning the availability of larger limits at the user's computer facility.I V.8 (Revised 5/81)
