4.3.1 Setting
During the installation, the water logic must be set in
function of the heating transmitters and the insulation
of the building.
The water logic curves (
¿JXUH
) refer to an ambient
setpoint of 20 °C.
The water logic slope (parameter 720) determines
the impact of variations in outdoor temperature on the
variations in heating start temperature.
The higher the slope the less the reduction in outdoor
