Key Features

   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
• CP2, CP3, CP4, CP5

   Constant speed mode

• Two constant speed modes - min. and max. -for constant flow applications
• CP1, CP6 or PP1, PP6

   Air-vent mode

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

   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.

   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
• PP2, PP3, PP4, PP5
