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
Valves and pumps can be controlled manually (–> section 3).
The default setting of the circulation pumps(for theheating circuit) is set for constant operation.

Parameters which do not allow the editing mode to activated are protected by a key
number. These parameters can only be altered as long as the key number is active af
ter selecting a protected function block (e.g. FB20) (–> section 2.4).
Change parameter.
Confirm parameter setting.
To adjust additional parameters, repeat the steps in the fields highlighted in gray.
Return to the operating level.
Note! Thecontroller automaticallyreturns to the operating level if the keys are left unpressedfor

2.4 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 106. To avoid unauthorized use of the key
number, remove the page or make the key number unreadable.
Proceed as follows:
0 0 0 0
blinks on the display.
Set valid key number.
Confirm key number.
When the correct key number is entered, the function block to be changed blinks on the
display, whereas the display does not blink when an incorrect key number is entered.
The key number remains active for approx. 5 minutes if the keys are left unpressed
during this time.

Start-up
2.5 Calibrating sensors
The connected sensors are calibrated in the configuration level. The following applies:
FB16 = ON, select “P1000“: Pt 1000 and Pt 100 sensors
4
FB16 = ON, select “ntc“: NTC and Pt 100 sensors
4
FB16 = OFF: PTC and Pt 100 sensors (default setting)
4
The resistance values of the sensors can be found on page 98.
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.
Perform the calibration in function block FB33. The function block FB33 always remains
activated.
Proceed as follows:
Switch to the parameter level.
Display: Time, blinks
Switch to the configuration level.
Display: Current system code number (Anl), blink
Select function block level 24 to 47.
Select function block FB33.
Activate function block FB33.
Display:
Enter currently valid key number.

Activate editing mode for sensor.
Correct measured temperature.
Read the actual temperature directly from the thermometer at the point of measure
ment and enter this value as the reference temperature.
Confirm corrected measured temperature.
Additional sensors are calibrated similarly.
Exit the configuration level.
Return to the operating level.
2.6 Resetting to default values
Start-up
-
All parameters and function blocks from any parameter level can be reset to their default settings (WE).
Proceed as follows:
Reset to default settings.
Function blocks and parameters are reset to their default settings (WE).
Note!
Resetting protected parameters to their default settings is only possible when the key number is
still active. The function block settings are kept.
Note!
The controller isready foroperation with its default settings. You just need to set the correctdate
and current time.
