Water Calculation Mode
The main parameter for conguration of space heating is the water calculation temperature.
The water calculation mode establishes the temperature setting for each circuit, selecting a function to assign each temperature
setting depending on the ambient temperature.
Each circuit has its own Water Calculation type for heating. Both circuits may be
congured as:
• Disabled
• Points
• Gradient
• Fix
To switch between them the variable type must be edited.
? NOTE
• Setting a space heating circuit at “None” does not deactivate it for space cooling. They are independent circuits.
• Installer may ban the possibility of switching between water calculation modes. In that case the user is not be able to edit the water calculation
variable type.
None
The “None” option sets the circuit as disabled.
Points
Points is the most versatile calculation type. The user sets four points that creates a line
representing the function that the Air to water heat pump will use to give the temperature
setting according to the current ambient temperature.
Gradient
It calculates the temperature setting using a gradient congured by the installer. In this view
the user may congure the same variables as in the “Points” view, but automatically. User
can only edit the gradient variable and it will automatically set the values for the other 4
variables on the chart.
? NOTE
The unique editable variable on that view is “Curve”.
