Water calculation mode
Disabled
The “Disabled” 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.
