4. ZONE-CONTROLThe function of the ZONE-CONTROL instruction is to provide information onzone temperature control characteristics such as set point, type of thermostat,and throttling range. A number of ZONE-CONTROL instructions may be entered toaccount for zone-to-zone variations in these characteristics and/or to permitcomparison studies.ZONE-CONTROL is a "subcommand" of ZONE and, as such, can be used to input·a subset of data to ZONE.An alternative mode for data entry is to complete and enter ZONE-CONTROLkeywords and their values directly into the ZONE command (if this approach ischosen, omit the ZONE-CONTROL keyword in ZONE).ZONE-CONTROLDESIGN-HEAT-Tinforms the SDL Processor that the data to follow are related·to control of zone temperature. A unique user-defined namemust be entered in the U-name field of each ZONE-CONTROLinstruction. ()nission of this entry in the "subcommand" willcause an error.specifies the space temperature that the program uses tocalculate the supply air flow rate required to meet peak (ordesign day) heating loads for the zone.See Sec. D of this chapter for discussion related to this andother system design calculations.Note that a DESIGN-HEAT-T must be specified for all ZONE-TYPE =CONDITIONED. -- --DESIGN-HEAT-T may also be specified for ZONE-TYPE = UNCONDITIONEDor PLENUM (in tnTs case, a value should be specified that isthe user's predicted temperature in this zone at the time ofpeak heating in adjacent zones, that~ those surroundingzones that share a common interior wall). If ZONE-TYPE =UNCONDITIONED or PLENUM and no value is specified forDESIGN-HEAT-T, it will default to the value for TEMPERATURE(see SPACE-CONDITIONS in LOADS).HEAT-TEMP-SCHis the U-name of the SCHEDULE instruction that specifies theset point of the zone heating thermostat. If no data entry ismade, the program will assume that the zone has nozone-activated heating control.See Chap. II for information on the SCHEDULE instruction. However,note that, in this case, the input for the DAY-SCHEDULEinstruction should be hourly room temperature.For additional discussion pertinent to the use of this keywordTOr slmuJatlon of zone thermostatlc contrOl-see:)ec:-B.6 ofthis chapter. - -- - -----The following is an example of data entry for the keywordHEAT-TEMP-SCH and the associated SCHEDULE instructions.IV.193 (Revised 5/81)
