Code WordTHERMOSTATICTABLE IV.30BASEBOARD-CTRLTemperature control of the baseboard element is by athermostat located within the zone.OUTDOOR-RESET Temperature control of the baseboard element is by athermostat located outside the building.If code-word THERMOSTATIC is entered, the program willassume that the baseboard element adds heat as required,up to the maximum capacity of the element, to maintainzone temperature within the heating throttling range.The baseboards are sequenced on first in response to adrop in space temperature.If no entry is made for this keyword (default), or if thecode-word OUTDOOR-RESET is entered, the program assumesthat baseboard heating output varies linearly with thetemperature of the outdoor air (i.e., circulating fluidtemperature is referenced to outside air temperature).The linear function and the operating period arespecified by keyword BASEBOARD-SCH (see SYSTEM-CONTROLsubcommand) .THERMOSTAT-TYPEInput for this keyword is the code-word that identifiesthe type of thermostat action to be simulated. See TableIV.31 for the code-words and a brief description of thetype of thermostat each represents. Note that theprogram will assume the same type of thermostat actionfor both cooling and heating.TABLE IV. 31Code-WordPROPORTIONALTWO-POS ITI ONTHERMOSTAT-TYPEThermostat throttles heat addition rate (or heatextraction rate) in linear proportion to thedifference between zone set point temperature andactual zone temperature. The proportional bandis input by the user (see keywordTHROTTLING-RANGE). PROPORTIONAL is the default.On-off type thermostat simulated as a very narrowfixed throttling range around each set point.This code-word is normally not used for hot andchilled water system controls.IV.195 (Revi sed 5/81)
