C. SDL INPUT INSTRUCTIONSCaution:Although the Reset Schedule Instructionsare the first SDL instructions to bediscussed, they are not necessarilyappropriate to your system. Chances are,they are not. l! Y~J! are ready to startentering data, you-shoUTO have by nowchosen a SYSTEM=rYPE. Refer-to-rhe-­Applicability Table for your SYSTEM-TYPE(Sec. ~ of this Chap:). It wi II tell ~if this instruction, and subsequentTnsTrUCtions are appropriate. Remember:Your Appl1cablTTty Table 1S your guide andit will simplify data entry.1. Reset Schedule Instructionsa. DAY-RESET-SCHb. RESET-SCHEDULEThe function of the reset schedule instruction is to define the relationshipsbetween a system control parameter and the outside air temperature foreach hour of the RUN-PERIOD. The instructions are applicable to controlparameters (such as hot deck temperature, cold deck temperature, and baseboardheating) only when the reset control strategy has been specified.The RESET-SCHEDULE instruction is identical to the SCHEDULE instructiondescribed in Chap. II. The user worksheet for the SCHEDULE instruction may beused for RESET-SCHEDULE with, of course, the proper substitution of commandwords. The LIKE keyword is not applicable to RESET-SCHEDULE, but it is applicableto DAY-RESET-SCH. The DAY-SCHEDULE instruction, however, is differentthan the DAY-RESET-SCH instruction. Rather than entering 24 hourly values, asnormally entered for a DAY-SCHEDULE instruction, four keywords and theirassociated values are entered for the DAY-RESET-SCH.DAY-RESET-SCHSUPPLY-HIinforms the SDL Processor that the data to follow willdefine how a system control parameter is to vary inresponse to changes in outside air temperature. An uniqueuser-defined name must be entered in the U-name field ofeach DAY-RESET-SCH instruction. Omission of this entrywill cause an error.is the upper supply air set-point temperature (or outputratio) corresponding to the user input value for OUTSIDE-LO.When this instruction is specified for the reset of coolingair or heating air temperature, the user input is a temperature.(See keywords HEAT-RESET-SCH and COOL-RESET-SCH inthe SYSTEM-CONTROL subcommand.) Fig. IV.1S illustratesthis application.IV.176(Revised S(81)
