Key Features

Constant speed mode

Two constant speed modes – min. and max. -for constant flow applications

 

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

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

ECO mode

• The factory setting, ECO, 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.
• ECO can be used in 80% of the heating system.

Air-vent mode

Press the setting button  for 6 seconds under this mode to vent air in the pump.
