Description

 HET Domestic Circulator Pump are high-efficiency circulators, designed for heating systems. The pump features AUTO function which automatically adjusts the pump to system demands for optimal comfort and the lowest energy consumption as well as simple commissioning.

Suitable for:

  • Commercial heating
  • Commercial hot water recirculation
  • Domestic hot water recirculation
  • Domestic heating
  • Industrial heating

Benefits

» Exceeding benchmark level of the Ecodesign Requirements for 2015(ErP) with EEI ≤ 0.20
» Providing energy savings and comfort level
» Automatic and continuous detection of optimal duty point by AUTO
» Automatic night setback function
» High safety – built-in electrical and thermal protection of the pump
» Self-venting pump housing
» LED display for indication of power and fault codes
» Fault prompt function
» Low noise level
» Based on 500,000 times test in extreme conditions

ⅠⅡⅢ

Constant speed mode

Three constant speed modes for constant flow applications

CP1 CP2

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)

PP1 PP2

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)

AUTO

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

Night mode

Night mode

The night mode reduces the power consumption to a minimum with power-saving features.
