Speed-controlled pump

Line no. Operating line

5530 Pump speed min

The minimum speed of the pump for instantaneous DHW heater can be defined. It is

thus possible to negate the lowest pump speeds, which cannot be properly controlled

Mixing valve control

Line no. Operating line

5544 Actuator running time

Setting the running time of the actuator used with the mixing valve.

6.19 Configuration

Procedure

First, make use of the presetting choices and enter the plant diagram that comes

closest to the plant in question. Then, modify manually the individual partial diagrams to

match them to the actual requirements.

After that, select the extra functions and make the fine-tuning via the operating lines of

the individual parameters.

Preselection of

plant diagram

Line no. Operating line

5700 Preselection

The plant diagrams shown in chapter “Applications“ can be preselected by entering a

diagram number. The plant diagram is the result of preselection plus the connected

sensors.

The sensors contained in the selected plant diagram must be connected to ensure that

automatic sensor identification will not detect some other plant diagram.

Manual setting /

adjustment of partial diagrams

The plant diagrams consist of several partial diagrams.

The required partial diagrams can be used to manually produce the required final plant

diagram.

But it is also possible to modify and adjust partial diagrams of a plant diagram

generated via “Presetting” (5700).

A catalog with partial diagrams, which is separately available, contains the partial

diagrams implemented in the controller – classified according to groups. Also listed in

the catalog are the required operating lines which must be set to produce the

respective partial diagrams, plus the sensors required for the relevant partial diagram.

On operating lines 6212 through 6217 (see page 175), you can check whether the

adjustments led to the right partial diagram. The check number shown there must

accord with the relevant components group.
