1 Operation
The controller is ready for use with the temperatures and operating schedules preset by the
manufacturer.
On start-up, the current time and date need to be adjusted at the controller (–> section 1.5).

The operating controls are located in the front panel of the controller and protected by a
Plexiglas door with an integrated quick guide.

1.2 Operating modes
Day mode (rated operation)
Regardless of the programmed times-of-use and summer mode, the controller uses the set
points relevant for rated operation.
The
DHW temperature set point
remains constantly active in system Anl 6.
Night mode (reduced operation)
Regardless of the programmed times-of-use, the controller uses the set points relevant for reduced operation.
The
Sustained DHW temperature
remains constantly active in system Anl 6.
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
depending on the outdoor temperature. The controller switches automatically between both
operating modes.
Manual operation – 0 +
Valves and pumps can be controlled manually (–> section 3).
The default setting of the circulation pump is permanent operation.

1.7 Presetting temperature set points
For the heating circuit, the desired room temperatures during the day (
Day set point
) and
during the night (
Night set point
) can be preset.
In the DHW circuit, the temperature you wish the domestic hot water to be heated to can be
adjusted.
The temperature set points are adjusted using the top rotary switch:
Desired temperature set point Position

tion can only be carried out after the valid key number has been entered.
The valid key number for initial start-up can be found on page 96. To avoid unauthorized
use of the key number, remove the page or make the key number unreadable.
2.1 Setting the system code number
Six different hydraulic schemes are available. Each system configuration is represented by a
system code number. The different schemes are dealt with in section 4. Available controller
functions are described in sections 5, 6 and 7.
Changing the system code number resets previously adjusted function blocks to their default
values. Function block parameters and parameter level settings remain unchanged.
The system code number is set in the configuration level.

CO-SYS -> F02 - 0: PTC sensors
The resistance values of the sensors can be found on page 91.
If the temperature values displayed on the controller differ from the actual temperatures, the
measured values of all connected sensors can be changed or readjusted. To calibrate a sen
sor, the currently displayed sensor value must be changed to match a temperature (reference
value) measured directly at the point of measurement.
Activate the sensor calibration in CO-SYS over function block F08.
An incorrect sensor calibration can be deleted by setting F08 - 0.
Proceed as follows:
Turn rotary switch “Configuration and parameterization“ to COPA.

3 Manual operation
Switch to manual operating mode to access all outputs (see wiring diagram in section 11).
When manual operation is activated using the rotary switch for “Operating modes“, the ro
tary switch “Configuration and parameterization“ should be in position INFO, otherwise the
pump level cannot be accessed over the rotary pushbutton.
Proceed as follows:
Turn rotary switch “Configuration and parameterization“ to INFO.
Turn “Operating modes“ switch to +, 0 or –.

4 Systems
Six different hydraulic schemes are available. The systems can be configured both as pri
mary and secondary systems. The fundamental hydraulic difference between a primary and
a secondary system (heat exchanger in the heating/DHW circuit replaced by a mixing valve)
is illustrated in Fig. 2. The controller settings do not have to be changed.

Boiler systems:
Based on the systems Anl 1 to Anl 3, one-stage boiler systems can be set up.
The boiler can be controlled by an on/off output (CO-SYS -> F05 - 0).
