HVACTemplates are used to quickly create an HVAC system for a building with one or more zones. The only inputs required are zone name, specific schedules used to control the HVAC system, and minimal other inputs to describe the desired HVAC system.
To see how HVACTemplates work, review the example files with names starting with HVACTemplate*. I do not think a template exists for ZoneHVAC:LowTemperatureRadiant:ConstantFLow.
The current template expansion program supports the following objects. These are the plant, system, thermostat, and zone templates. Typically, one of each of these is required. The plant type is used when chilled or hot water loops are needed. If there are no plant loops, this template is not used. The system type is used for each HVAC system. The thermostat type is used to populate the zones with a thermostat. And finally, the zone type is used for zone equipment in each zone.

Many other objects are created when using templates. For example, the HVACTemplate_5ZoneBaseboardHeat.idf file was modified (by removing 4 of the zone baseboard heat templates) to keep only a single zone template for the baseboard. This example system uses 4 template objects.
HVACTemplate:Thermostat,
HVACTemplate:Zone:BaseboardHeat,
HVACTemplate:Plant:HotWaterLoop,
HVACTemplate:Plant:Boiler,
When this simulation is executed, the template objects will be expanded to create all required objects for the HVAC system specified. The expanded system will be saved in the expidf file and can be viewed after the simulation completes. Template objects in the input file will be commented out, and the objects added due to expansion are added at the end of the input file.
The first 4 objects below are the HVACTemplates in the original (modified) file. In the expidf file, these are commented out since they are no longer needed and have been replaced with the required EnergyPlus objects. It is apparent from this example that using templates can save a significant amount of time setting up the HVAC system.

HVACTemplates are used to quickly create an HVAC system for a building with one or more zones. The only inputs required are zone name, specific schedules used to control the HVAC system, and minimal other inputs to describe the desired HVAC system.
To see how HVACTemplates work, review the example files with names starting with HVACTemplate*. I do not think a template exists for ZoneHVAC:LowTemperatureRadiant:ConstantFLow.
The current template expansion program supports the following objects. These are the plant, system, thermostat, and zone templates. Typically, one of each of these is required. The plant type is used when chilled or hot water loops are needed. If there are no plant loops, this template is not used. The system type is used for each HVAC system. The thermostat type is used to populate the zones with a thermostat. And finally, the zone type is used for zone equipment in each zone.

Many other objects are created when using templates. For example, the HVACTemplate_5ZoneBaseboardHeat.idf file was modified (by removing 4 of the zone baseboard heat templates) to keep only a single zone template for the baseboard. This example system uses 4 template objects.
HVACTemplate:Thermostat,
HVACTemplate:Zone:BaseboardHeat,
HVACTemplate:Plant:HotWaterLoop,
HVACTemplate:Plant:Boiler,
When this simulation is executed, the template objects will be expanded to create all required objects for the HVAC system specified. The expanded system will be saved in the expidf file and can be viewed after the simulation completes. Template objects in the input file will be commented out, and the objects added due to expansion are added at the end of the input file.
The first 4 objects below are the HVACTemplates in the original (modified) file. In the expidf file, these are commented out since they are no longer needed and have been replaced with the required EnergyPlus objects. It is apparent from this example that using templates can save a significant amount of time setting up the HVAC system.

HVACTemplate:Zone:WaterToAirHeatPump
Many other objects are created when using templates. For example, the HVACTemplate_5ZoneBaseboardHeat.idf file was modified (by removing 4 of the zone baseboard heat templates) to keep only a single zone template for the baseboard. This example system uses 4 template objects.
HVACTemplate:Thermostat,
HVACTemplate:Zone:BaseboardHeat,
HVACTemplate:Plant:HotWaterLoop,
HVACTemplate:Plant:Boiler,
When this simulation is executed, the template objects will be expanded to create all required objects for the HVAC system specified. The expanded system will be saved in the expidf file and can be viewed after the simulation completes. Template objects in the input file will be commented out, and the objects added due to expansion are added at the end of the input file.
The first 4 objects below are the HVACTemplates in the original (modified) file. In the expidf file, these are commented out since they are no longer needed and have been replaced with the required EnergyPlus objects. It is apparent from this example that using templates can save a significant amount of time setting up the HVAC system.
