Weather-dependent curve

To be able to compensate for differences in temperature, the unit relies on its

weather-dependent curve. This curve defines how much the temperature of the

tank or leaving water must be at different outdoor temperatures. Because the

slope of the curve depends on local circumstances such as climate and the

insulation of the house, the curve can be adjusted by an installer or user.

Types of weather-dependent curve

There are 2 types of weather-dependent curves:

▪

2-points curve

▪

Slope-offset curve

Which type of curve you use to make adjustments, depends on your personal

preference. See

"Using weather-dependent
