S-3; SYSTEM Keyword ; ValueKeyword ; ValueFAN-SCHEDULEF-SCH2Keyword ; Val ueKeyword ; ValueIf the system fans must operate continuously because ofventilation requirements, or some other reason, but system heatingand/or cooling is deactivated during off-hours, the keywordsHEATING-SCHEDULE and/or COOLING-SCHEDULE can be used to simulate thiscondition. Note, however, that baseboard heating is also turned offwhen heating is deactivated in this manner.Case 10Addition of Baseboard HeatThermostatically controlled or outdoor-reset baseboard heatingmay be added to any of the control schemes described in the previouscases.When thermostatically controlled baseboard heating is specified,by entry of a value for keyword BASEBOARD-RATING and entry of thecode-word THERMOSTATIC for the keyword BASEBOARD-CTRL (both in theZONE instruction), the program simulates control of the baseboardelement in sequence with the system heating component, starting withthe baseboard and turning on the system component only after maximumbaseboard capacity has been reached. Baseboard heating is assumed tobe available whenever heating is available (see keyword HEATING­SCHEDULE in SYSTEM-CONTROL subcommand).When outdoor-reset baseboard heating is specified, by entry of avalue for BASEBOARD-RATING as above, the baseboard output is independentof the zone temperature. A reset schedule that defines therelationship between the hourly baseboard output and the outsidetemperature must be entered. A data entry for the keywordBASEBOARD-SCH is required to reference the reset schedule (seeSYSTEM-CONTROL subcommand).IV.175 (Revised 5/81)
