Water calculation mode
Deactivated
The “Deactivated” option sets the
circuit as disabled.
Points
Points is the most versatile calculation type.
Set 4 points and one vertex point, to create
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.
Use the down arrow key to select the
parameter to modify. Then modify the value
using the left and right arrow keys.
Vertex offset
High ambient temperature
Low ambient temperature
Set point at low ambient temperature
Set point at high ambient temperature
Gradient
Configure 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.
Use the down arrow key to select the parameter
to modify. Then modify the value using the left
and right arrow keys.
Vertex offset
Gradient curve
Fix
Set the circuit’s temperature to a defined
value, forcing the unit to maintain it.
Fixed temperature
