(3) Specify COOL-TEMP-SCH in the ZONE-CONTROL subcommand and anassociated SCHEDULE with hourly values of desired ZONE temperaturefor cooling. These temperatures will be used to operate theinduction box in the cool ing mode. If the user does not specify aCOOL-TEMP-SCH for a ZONE, it will be cooled (unless theCOOLING-SCHEDULE is set to off) but there will be no control of thecool ing process. -(4) Specify HEAT-TEMP-SCH in the ZONE-CONTROL subcommand and anassoc ia ted SCHEDULE with hourly val ues of des ired ZONE temperaturefor heating. These temperatures will be used to modulate the outputof the zone coil. If the user does not specify a HEAT-TEMP-SCH fora ZONE, the only heating available will be from the supply air andlight heat.(5) Specify THERMOSTAT-TYPE = PROPORTIONAL (the default) in theZONE-CONTROL subcommand. This assures a variable volume air flowentering the induction box for cooling and a constant volume airflow entering the induction box for heating.(6) Specify a value for REHEAT-DELTA-T in the SYSTEM-TERMINALsubcommand. This indicates to the program that zone (reheat) coilsare to be used in the ZONEs and it also indicates the maximumincrease in temperature of the supply air pass ing over the zonecoils.(7) The desired control strategy for the system has now been specified.To complete the input, specify values for the other keywords thatare appropriate to this SYSTEM-TYPE, or allow these keywords todefault. This example is the first strategy in Table IV.29.I V.163 (Revised 5/81)
