1.2 Operating modes

Day mode (rated operation)

Regardless ofthe programmed times-of-use and summer mode,the set points relevant for rated operation are used by the controller.

Night mode (reduced operation)

Regardless of the programmed times-of-use, the set points relevant for reduced operation are used by the controller.

Automatic mode

During the programmed times-of-use, the controller works in rated operation. Outside these times-of-use, the controller is in reduced operation, unless control operation is deactivated de pending on the outdoor temperature. The controller switches automatically between both oper ating modes.

Manual operation+ 0 –

Valves and pumps can be controlled manually.

1.6 Setting the times-of-use

Two times-of-use can be set for each day of the week. If just one time-of-use is required, the start and stop times of the second time-of-use must be programmed to identical times. The time schedules for the three heating circuits, DHW heating and the circulation pump can be read over Modbus. Pump circuits are treated as mixer circuits.

2.3 Changing parameters

Depending on the set system code number and the activated functions, not all parameters listed in the parameter list in the Appendix (–> section 12.2) might be available.

The parameters are grouped by topics:

PA1: Heating circuit 1

PA2: Heating circuit 2

PA3: Heating circuit 3

PA4: DHW heating

PA5: System-wide parameters

PA6: Does not exist

PA7: LON communication

PA8: Does not exist

PA9: Communication

Proceed as follows:

Switch to configuration and parameter level. Display shows:

Select parameter level. Open parameter level. Select parameter. Activate editing mode for the parameter. Edit the parameter. Confirm the parameter setting.

To adjust additional parameters, repeat the steps in the fields highlighted in gray.

Exit parameter level. Return to the operating level.

Start-up

2.3.1 Enter key number

Some functions are protected against unintentional or unauthorized access. These functions can only be activated or deactivated after the valid key number has been entered. The valid key number for initial start-up can be found on page 137. To avoid unauthorized use of the key number, remove the page or make the key number unreadable.

Proceed as follows:

0 0 0 0

The key number remains active for approx. 10 minutes.

blinks on the display. Set valid key number. Confirm key number.

When the correct key number is entered, the function block that is to be changed blinks on the display. On entering an incorrect key number, the controllers switches to the next configuration level.

2.4 Configuring universal inputs

The connected sensors are calibrated in Co6 configuration level. The following applies:

Co6 -> Fb00 = ON: Pt 100/Pt 1000 sensors (default setting)

Co6 -> Fb00 = OFF: Pt 100/PTC sensors

The resistance values of the sensors can be found on page 128. Each universal input can be configured separately. The following inputs Ni 200/1000, PTC, NTC, Pt 100/1000, (0/4...20) mA, (0–10 V) can be configured as function block parameters. The function blocks 01 to 17 correspond to the binary inputs BE1 to BE17 in the terminal wiring plan (page 92 onwards). The function block for the required sensor is activated and the function block parameter selected which corresponds to the type of input signal.

2.5 Calibrating sensors

If the temperature values displayed at the controller differ from the actual temperatures, the measured values of all connected sensors can be changed or readjusted. To calibrate a sensor, the currently displayed sensor value must be changed such that it matches the temperature (ref

erence temperature) measured directly at the point of measurement. Sensor calibration is to be activated in Co6 via function block Fb23.

Proceed as follows:

Switch to configuration and parameter level. Display shows:

PA1

Select Co6 level. Open Co6 level. Display shows:

Fb00

Select function block Fb23. Confirm selection. Display shows:

0 0 0 0

Enter and confirm key number. Fb23 blinks on the display.

Activate editing mode for function block. Activate function block. Start sensor calibration. Select the function block for the sensor that you want to calibrate:

The function blocks Fb01 to Fb17 correspond to the inputs in the terminal wiring plan (page 92 onwards) e.g. Fb02 = BE2

Activate editing mode for function block. Fb_ blinks on the display.

Display measured value. Activate editing mode for measured value.

Measured value blinks on the display. Correct measured temperature. Read the actual temperature directly from the ther

mometer at the point of measurement and enter this value as the reference tempera

ture. Confirm corrected measured temperature.

Additional sensors are calibrated similarly.

Note! The sensor values adjusted are not reset by the Loading default settings function.

2.6 Resetting to default values

All parameters and function blocks from any parameter level can be reset to their default set tings (WE).

Proceed as follows:

Reset to default settings. Function blocks and parameters are reset to their default settings (WE).

Note!

When the key number is active, thefunction blocksprotected bythe key number are also reset to their default settings. The controller isready foroperation with its default settings. You just need to set the correctdate and current time.

Switch to manual mode to configure all outputs (see wiring diagram in section 11).

Proceed as follows:

Position all selector mode switches to +, 0 or –. Select

pump manual level. Open pump manual level. Select pump PU1 to PU5:

PU1: BA11 PU2: BA12 PU3: BA13 PU4: BA14 PU5: BA15

Confirm pump selection. The display blinks.

Activate output: Deactivate output:

Confirm setting. The modified values remain active as long as the controller is in manual mode.

Move slide switch from 0, + or –. Exit manual level.

Note! In manual mode, frost protection is not guaranteed.
