Upper limit maps
This section explains the different upper limit maps referenced by Hybrid GHP/EHP control.
Upper limit maps are tables that define values that are the upper limits for GHP/EHP for the current system load levels, and the upper limit map
referenced depends on the Hybrid GHP/EHP control mode setting.
The system references maps to be used from one of the following 5 types according to the settings of this unit.
Cost priority map
Referenced with cost priority control.
As this map is automatically generated based on the power costs/gas costs values set in the “Cost settings” screen, these vary depending on
the settings.
You can view the upper limit map that has been generated according to the current settings in the “Check upper limit map” screen.
Energy priority map
Referenced with energy priority control. Values are fixed in the following map.
