Code-WordHOT-WATERELECTRICGAS-FURNACEOIL-FURNACETABLE IV.41HEAT-SOURCE, ZONE-HEAT-SOURCE,PREHEAT-SOURCE, and BASEBOARD-SOURCEThe source of heat is hot-water, provided byconventional equipment specified in the PLANT program.This code-word is appropriate for central heatingcoils, preheat coils, baseboard heaters, and zoneheating coils. (It is possible to utilize solar energyby using the HEAT-RECOVERY command in PLANT).The source of heat is an electric resistance element.This code-word is appropriate for central heatingcoils, preheat coils, baseboard heaters, and zoneheating coils.The source of heat is a gas-fired furnace, which willbe simulated here in SYSTEMS.The source of heat is an oil-fired furnace, which willbe simulated here in SYSTEMS.HEAT-PUMP The source of heat is an air-to-air heat pump. Note:This code-word is appropriate only as a HEAT-SOURCE forthe RESYS and PTAC systems. It should not be used forany other systems (see the HP system).HOT-WATER/SOLAR The source of heat (total or assist) is eitherhot-water provided by conventional plant equipment orhot water/air provided by solar equipment, if present.If there is no solar equipment present, the source willbe treated just as simply HOT-WATER. This code-word isappropriate for central heating coils, preheat coils,and zone heating coils. Sources of the solar type arepassed to CBS (in PLANT) via the PLANT-l component.This code-word is not appropriate to the HP system.IV.260 (Revised 5/81)
