Controllers
Information
All control blocks that form the control sequence of a system are instantiated into one single class, a so-called control section. This package contains such control sections for heat pump plant models.

Buildings.Templates.Plants.HeatPumps.Components.Controls.AirToWater
Controller for AWHP plant
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 parameternSenDpHeaWatRem. - 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 parameternSenDpChiWatRem. -
Inside the sub-bus
busAirHan[:]orbusEquZon[:], with a dimensionality of one- HW plant requests yielded by the air handler or zone
