Information

This class implements the sequence of operation for plants with air-to-water heat pumps. It is based on the controller Buildings.Templates.Plants.Controls.HeatPumps.AirToWater.

Control points

The control sequence requires the following external input points in addition to those already included in the HP plant template.

• Outdoor air temperature TOut: AI signal with a dimensionality of zero
• HW differential pressure from remote sensor(s) dpHeaWatRem: AI signal with a dimensionality of one, the number of remote sensors is specified by the parameter nSenDpHeaWatRem.
• CHW differential pressure from remote sensor(s) dpChiWatRem – only for heating and cooling plants: AI signal with a dimensionality of one, the number of remote sensors is specified by the parameter nSenDpChiWatRem.
• Inside the sub-bus busAirHan[:] or busEquZon[:], with a dimensionality of one
  • HW plant requests yielded by the air handler or zone equipment controller bus(AirHan|EquZon)[:].reqPlaHeaWat: AI signal (Integer), with a dimensionality of one
  • HW reset requests yielded by the air handler or zone equipment controller bus(AirHan|EquZon)[:].reqResHeaWat: AI signal (Integer), with a dimensionality of one
• CHW plant requests yielded by the air handler or zone – only for heating and cooling plants: equipment controller bus(AirHan|EquZon)[:].reqPlaChiWat: AI signal (Integer), with a dimensionality of one
• CHW reset requests yielded by the air handler or zone – only for heating and cooling plants: equipment controller bus(AirHan|EquZon)[:].reqResChiWat: AI signal (Integer), with a dimensionality of one
