Application
Domestic hot water circulation systems of all kinds, hot-water heating systems of all kinds, air-conditioning systems, closed cooling circuits, industrial circulation systems.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
