Equipment/function
Applications

The pump enables fine-tuning of the control method for the specific application in each individual installation (e.g. radiator, underfloor heating, ceiling cooling) while operating at the highest efficiency.

Heating

• Radiator
• underfloor heating;
• Ceiling heater;
• Air heater
• Chimney
• heat exchanger,

Cooling

• Ceiling Cooling
• Floor cooling
• Air conditioners
• Chimney
• heat exchanger,

Combination of heating and cooling

• Automatic switching

Depending on the selected application, the following control methods are available:

Modes of control

• Constant speed (control mode)
• Δp-c for constant differential pressure
• Δp-v for variable differential pressure
• Dynamic Adapt plus for continuous (dynamic) adaptation of the capacity to the current requirements
• T-const. for continuous temperature regulation
• ΔT for differential temperature control
• Constant Q for continuous flow regulation
• Multi-Flow Adaptation: determination of the total flow rate through the supply pump for the necessary feed of the secondary pumps in the heating circuit distributors
• User defined PID control

Optional functions

• Q-Limitmax. to limit the maximum flow
• Q-Limitmin. to limit the minimum flow
• No-Flow Stop (shut-off at no flow)
• Automatic night setback
• Pessimum point control (Δp-c with external real state sensor)
• Thermal disinfection detection (Stratos MAXO-Z)
• Variable slope characteristic Δp-v

Manual settings

• Selecting the application via the Setup Guide
• Adjustment of the respective operating parameters
• Nominal operating point: direct entry of the calculated operating point at Δp-v
• Status display
• Setting and resetting the energy meter (amount of heat and cooling)
• Pump ventilation function
• Key lock for locking the settings
• Function for resetting to factory settings or saved restore points (parameter sets)
• Input of analog input parameters
• Input of binary input parameters
• Input of relay output parameters
• Dual pump operation (with two single pumps to be operated as a dual pump)

Automatic control

• Demand-optimized power control for energy-efficient operation
• Downstream operation identification
• No-flow shutdown (No-Flow Stop)
• Soft start
• Automatic troubleshooting procedures (e.g. unblocking function)
