Heating and cooling combined
- Automatic switchover (version “-R7”: not possible; however, possible with Stratos MAXO temperature sensor)
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 control
- ΔT-const. for constant 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 control
Optional functions
- Q-Limitmax. for limiting the maximum volume flow
- Q-Limitmin. for limiting the minimum volume flow
