Pre-defined applications in the settings assistant

Radiator – Differential pressure Δp-v

For the “Heating with radiators” application, there is an optimized variable differential pressure control. Consumer loads with connected radiators can be supplied with a variable differential pressure control (Δp-v) according to the needs.
Assuming a maximum required delivery head at the design point, the pump variably adjusts the differential pressure to the volume flow. The volume flow varies through the open and closed valves at the consumers. The pump output is adjusted to the requirements of the consumer load and the energy requirement is significantly reduced.

Radiator – Hall temperature T-const

For applications, in which the pump supplies only one room/hall with radiators, there is a temperature control, which not only adjusts the pump output to the temperature requirements of a room/hall, but also controls the temperature of the room/hall. This control mode does not require hydraulic control valves and prevents hydraulic loss.
In order to control the hall temperature, the pump requires a temperature sensor, which records the current temperature of the room. For this purpose, commercially available temperature sensors such as PT1000 sensors can be connected to an analogue input of the pump.

Drinking water – Temperature T-const

• Detection of disinfection:

The “Detection of disinfection” function has been provided in the “Set auto control” menu after having selected the “Drinking water – temperature T-const” application in the settings assistant.
This function monitors the feed temperature at the hot water source with an external temperature sensor in order to record the significant increase of temperature in case of thermal disinfection.
Once the system detects thermal disinfection, the pump switches to maximum output to support disinfection and rinse the system with hot water.

NOTICE: If the “Detection of disinfection” option is not used, the pump reduces the power when it detects a temperature increase. This prevents thermal disinfection.
Ensure the system is rinsed with hot fluid on the basis of other measures:

• Manual selection of “MAX” function in the “Settings” “Manual operation” menu.

• External control of the “External MAX” function through a binary input.
