Equipment/function

Field of application

The pump facilitates an operation with highest system efficiency via precise setting of the control mode for the system-specific application (e.g. radiator, underfloor heating, ceiling cooling).

Heating

  • Radiator
  • Underfloor heating
  • Ceiling heating
  • Fan heater
  • Hydraulic shunt
  • Heat exchanger

Cooling

  • Ceiling cooling
  • Underfloor cooling
  • Air-conditioning devices
  • Hydraulic shunt
  • Heat exchanger

Heating and cooling combined

  • Automatic switchover

The following control modes are available depending on the selected application:

Control modes

  • Constant speed (control mode)
  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • Dynamic Adapt plus for continuous (dynamic) adjustment of the delivery rate to the current requirement
  • T-const. for constant temperature regulation
  • ΔT for differential temperature control
  • Constant Q for constant volume flow control
  • Multi-Flow Adaptation: Total volume flow determination through the feeder pump for the needs-based supply of secondary pumps in the heating circuit distributors
  • User-defined PID controller

Optional functions

  • Q-limitmax. for limiting the maximum volume flow
  • Q-limitmin. for limiting the minimum volume flow
  • No-Flow Stop (zero-flow-deactivation)
  • Automatic setback operation
  • Index circuit evaluator (Δp-c control with external actual value sensor)
  • Thermal disinfection detection
  • Variable pitch of Δp-v pump curve

Manual settings

  • Selection of the field of application using the Setup Guide
  • Setting the related operating parameters
  • Nominal duty point: direct input of calculated duty point at Δp-v

  • Pump venting function
  • Key lock for disabling the settings
  • Function for resetting the factory settings or the saved restoration points (parameter sets)
  • Parameterising the analogue inputs
  • Parameterising the binary inputs
  • Parameterising the relay outputs

Automatic functions

  • Power adjustment according to requirements for energy-efficient operation depending on the operating mode
  • Setback operation
  • Deactivation at zero flow (No-Flow Stop)
  • Soft start
  • Automatic troubleshooting routines (e.g. deblocking function)
  • Switchover heating/cooling mode
  • Full motor protection with integrated trip electronics

External control inputs and their functions

2 x analogue inputs:

  • Signal types: 0 – 10 V, 2 – 10 V, 0 – 20 mA, 4 – 20 mA, PT1000
  • Applications: Remote adjustment of the setpoints in every control mode (except Multi-Flow Adaptation), sensor inputs for temperature, differential pressure or free sensor in user-defined PID-operating mode

2 x digital inputs:

  • For potential-free control outputs or switch
  • Parametrizable functions:
    • Ext. Off
    • Ext. Min
    • Ext. Max
    • MANUAL (BMS-OFF)
    • Key lock
    • Switchover between heating/cooling mode
