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
• Heat exchanger

Cooling

• Ceiling cooling
• Underfloor cooling
• Air-conditioning devices
• 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-limit_max. for limiting the maximum volume flow
• Q-limit_min. 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 (Stratos MAXO-Z)
• 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
• Status display
• Setting and resetting the energy meters (heating and cooling)
• 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
• Dual pump function (for 2 single pumps, which should be operated as twin-head pump)

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

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
