Settings assistant
Thanks to the settings assistant, it is no longer necessary to be familiar with the matching control mode and additional options of the corresponding application.
You can select the matching control mode and additional options in the application’s settings assistant.
You can also directly select a basic control mode in the settings assistant.
Selection via the application
In the 
“Settings” menu, select
- “Set auto control”
- “Settings assistant”.
Possible application selection:
The “Heating” application is used as an example.
Select the “Heating” application by turning the operating button and press to confirm.
Different system types are available depending on the applications.
The following system types are available for the “Heating” application:
System types for heating application |
|---|
‣ Radiator |
‣ Underfloor heating |
‣ Ceiling heating |
‣ Fan heater |
‣ Hydraulic shunt |
‣ Heat exchanger |
‣ Basic control modes |
The “Radiator” system type is used as an example.
Select the “Radiator” system type by turning the operating button and press to confirm.
Different control modes are available depending on the system type.
For the “Radiator” system type in the “Heating” application, the following control modes are available:
Control mode |
|---|
‣ Differential pressure ∆p-v |
‣ Dynamic Adapt plus |
‣ Hall temperature T-const |
Example: Control mode “Dynamic Adapt plus”
Turn the operating button to select “Dynamic Adapt plus” control mode. Press the operating button to confirm.
No other settings are required in Dynamic Adapt plus.
Once you have confirmed the selection, it is displayed in the “Settings assistant” menu.
Direct selection of a basic control mode
In the “Settings” menu, select
- “Set auto control”
- “Settings assistant”
- “Basic control modes”.
The following basic control modes are available:
Basic control modes |
|---|
‣ Differential pressure ∆p-c |
‣ Differential pressure ∆p-v |
‣ Index circuit ∆p-c |
‣ Dynamic Adapt plus |
‣ Volume flow Q-const |
‣ Multi-Flow Adaptation |
Temperature T-const |
‣ Temperature ∆T-const |
‣ Speed n-const |
‣ PID control |
A control mode with temperature controller, index circuit Δp-c control and the PID control also requires the selection of actual value- or sensor source (analogue input AI 1/AI 2, internal sensor).
When you confirm a selected basic control mode, the “Settings assistant” sub-menu appears, displaying the selected control mode in the information bar.
You see more menus under the display. These are intended for parameter configuration.
For example: Input of the setpoint for differential pressure control, activation/deactivation of setback operation, No-Flow Stop function or input emergency operation speed.
Heating & cooling application
The “Heating & cooling” application combines both the applications. The pump is set separately for both applications and can switch between both applications.
In the “Settings” menu, select
- “Set auto control”
- “Settings assistant”
- “Heating & cooling”.
Select the control mode for the “Heating” application first.
System types for heating application | Control mode |
|---|---|
‣ Radiator | Differential pressure Δp-v Dynamic Adapt plus Hall temperature T-const |
‣ Underfloor heating ‣ Ceiling heating | Differential pressure Δp-c Dynamic Adapt plus Hall temperature T-const |
‣ Fan heater | Differential pressure Δp-v Dynamic Adapt plus Hall temperature T-const |
‣ Hydraulic shunt | Feed temperature T-const Return ΔT |
‣ Heat exchanger | Feed temperature T-const Feed ΔT |
‣ Basic control modes | Differential pressure Δp-c Differential pressure Δp-v Index circuit Δp-c Dynamic Adapt plus Volume flow cQ Temperature T-const Temperature ΔT-const Speed n |
After having selected the desired system type and control mode for the “Heating” application, select the control mode for the “Cooling” application.
System types for cooling application | Control mode |
|---|---|
‣ Ceiling cooling ‣ Underfloor cooling | Differential pressure Δp-c Dynamic Adapt plus Hall temperature T-const |
‣ Air-conditioning device | Differential pressure Δp-v Dynamic Adapt plus Hall temperature T-const |
‣ Hydraulic shunt | Feed temperature T-const. |
‣ Heat exchanger | Feed temperature T-const Feed ΔT |
‣ Basic control modes | Differential pressure Δp-c Differential pressure Δp-v Index circuit Δp-c Dynamic Adapt plus Volume flow cQ Temperature T-const Temperature ΔT-const Speed n |
A control mode with temperature control also requires assignment of sensor source.
If the selection is made, the sub-menu “Settings assistant” will appear with the display of selected system type and control mode.
NOTICE
The menu “Heating/cooling switchover” for further adjustments is available only if all settings have been made for “Heating & Cooling” application.
Heating/cooling switchover
Initially select “Heating” in the “Heating/cooling switchover” menu.
Then configure additional settings (e.g. setpoint specification, setback operation, etc.) in the “Set auto control” menu.
The settings for cooling are made once the specifications for heating are completed. To do this, select “Cooling” in the “Heating/cooling switchover” menu.
More settings (e.g. setpoint, Q-LimitMax,…) can be made in the “Set auto control” menu.
In order to adjust the automatic switchover between heating and cooling, select “Automatic” and enter the switchover temperature each for heating and cooling.
If the switchover temperatures are exceeded or not reached, the pump automatically switches between heating and cooling.
NOTICE
If the switchover temperature for heating in the fluid is exceeded, the pump operates in heating mode.
If the fluid temperature drops below the cooling switchover temperature, the pump operates in cooling mode.
In the temperature range between the two switchover temperatures, the pump remains inactive. It conveys the fluid occasionally only for measuring the temperature.
Proceed as follows to prevent inactivity:
• Set the switchover temperatures for heating and cooling to the same temperature.
• Select the switchover method using a binary input.
For an external switchover between “Heating/cooling”, select “Binary input” in the “Heating/cooling switchover” menu.
The binary input must be set to “Switching heating/cooling” function.
NOTICE
When using the heating/cooling quantity measurement, the energy is automatically logged in the respective correct counter for heat and cooling energy meter.
