Thermostat Module

  • Shutdown temperature adjustable from 35 °C to 75 °C
  • Start point 7 K below the shutdown temperature
  • Adjustable via pushbuttons
  • Continuous operation and permanently off functions
  • Adjustable speed
  • Average power consumption for approx. 12 hours of runtime/day: less than 3 watts

THERMOSTAT MODULE

HOW IT WORKS

A control thermostat integrated into the pump motor switches off the pump at the set temperature. The pump automatically switches on again when the water in the DHW circulation line has cooled by 7 degrees.

Perfect for detached and two-family houses

Hot water is available at the draw-off points around the clock, without having to continuously run the pump. Pump runtime is reduced by approx. 65 %.

Save even more

If the pump is connected to an external time controller (e.g. to a timer or the DHW heater's time controller), pump runtimes can be reduced even further.


PUMP HOUSING

V-pump housing

1 1/4" male connection thread; fitting set, with 1/2" male screw/solder fitting/ø 15 mm female, non-return valve, cut-off valve, insulation shell

R-pump housing

1/2" female connection thread, insulation shell

 

DRIVE

Permanent magnet drive

The BlueOne DHW circulation pump generation is driven by a highly efficient, electronically commutated DC motor. A voltage transformer is integrated in the module cap for AC operation. All pumps have continuous manual speed adjustment.

Spherical motor technology

The shaftless spherical motor does not feature a revolving bearing shaft. Instead, the stator transfers the rotating magnetic field directly to the permanent magnet rotor on a fixed bearing pin. The rotor bearing is self-adjusting and lubricated by the water. The rotor thus runs with zero play and is virtually noise free. Water carrying parts can be easily cleaned if necessary. The rotor can be replaced when required.

 

CONTROL MODULE

ERT - ELECTRONIC CONTROL THERMOSTAT

The thermostat switches off the pump at the set temperature. The shutdown temperature is set using a pushbutton and is immediately active.

  • Shutdown temperature adjustable in 5° increments from 35 °C to 75 °C
  • Start point 7 K below the shutdown temperature
