Constant pressure mode

• The pump maintains constant pressure regardless of the flow
• The preferred operation mode for under floor heating and 2 string systems with low flow variation
• Constant pressure curves (low and high)

Proportional pressure mode

• If the proportional pressure mode is selected, the differential pressure varies proportionally with the flow, i.e. higher flow means higher differential pressure
• Proportional pressure is the preferred choice for one-string systems with high flow variation
• Proportional pressure curve (high and low)

Autoadapt mode

• The factory setting, AUTO, analyzes the heating system and automatically adjusts the pump setting to meet the heating requirement. The result is optimum comfort and a minimum of energy consumption.
• AUTO can be used in 80% of the heating system
