IF the system (or zone) does nothave heating capability, entry for keyword HEAT-TEMP-SCH should beomitted. If the system (or zone) does not have cooling capability, entryfor keyword COOL-TEMP-SCH should be omitted.Note that entry of both DESIGN-HEAT-T and DESIGN-COOL-T is required inany case (program wi 11 abort if entry for either is omitted). These twokeywords are shown in the above example, and in those that follow, merelyto illustrate this requirement although they do not provide informationrelated to thermostat simulation. They do provide information for thecalculation of zone supply air flow rate (see Sec. 0.1 of this chapter).Case 2 - TWO-POSITION Heating or Cooling Thermostat Operation withSeasonal ResetThis simulation is exactly as shown for Case 1, except that only onetemperature set point can be active at any given time. To simulate thiscondition, the heating capability of the system serving the zone must beIV.165 (Revised 5/81)
