been selected for the "Levelcontrol' make-up variant.
–
Use the arrow keys at the operator panel to select "PU" on the
display.
–
"PU" flashes on the display to visually indicate that the
pump has been selected for the "Magcontrol' make-up variant.
2.
Press "OK" on the controller's operator panel.
–
The pump is switched on and the displays shows "PU!".
–
The display must show values of ≥
5 bar for the pressure for the
activated pump.
3.
Press "OK" on the controller's operator panel.
–
The pump is switched off and the displays shows "PU".
The function test for the pump is completed. Slowly open the "BV" shut-off valve
in the pressure line from the pump to the system circuit.
Note!
If the pressure does not rise when the pump is activated:
•
Shut down the pump.
•
Vent the pump, see chapter 7.3 "Filling the device with water" on
page 9 .
Note!
Execute a function test of the system separator tank according to the
user-supplied specifications.
7.7
Use the device to fill the facility system with water
You have the option to use the device to fill the system circuit with water. These
requirements must be met for the filling with water:
•
The system circuit has not been previously filled with water.
•
The system circuit has a maximum water volume up to 3,000 litres.
•
It is a system circuit with a diaphragm expansion system.
Set the following operating modes at the controller:
•
"Magcontrol" make-up, see chapter 9.2.1 "Customer menu" on page 13 .
•
Manual operation, see chapter 8.1.2 "Manual mode" on page 11 .
Proceed as follows:
1.
Press "Manual" on the controller's operator panel.
2.
Use the arrow keys at the operator
panel to select "Fill" on the display.

Filling
–
"Fill" flashes on the display to visually indicate the selection.
3.
Press "OK" on the controller's operator panel.
–
The pump is switched on and the displays shows "Fill!".
–
The controller calculates the required filling pressure. As soon as this
value has been attained, the controller automatically stops the filling
process.
The system circuit is filled with water.
Note!
Monitor the system for the entire automatic filling process.
Note!
If the maximum filling time (10 hours by default) is exceeded, the
system aborts the make-up process with an error message.
•
After the cause has been found, acknowledge the error message
by pressing "Quit" at the controller's operating panel and
continue with the filling process, see chapter 9.3 "Messages" on
page 14 .

Starting Automatic mode
Automatic operation can be started after initial commissioning. The following
prerequisites must be met for automatic operation:
•
"P
0
" minimum working pressure is entered in the controller.
•
The device is filled with water.
•
All required parameters are defined in the controller.
•
The function test has been concluded.
Start the automatic mode at the operator panel of the controller:
•
Press "Auto" for automatic operation.
•
The "Auto" LED at the operator panel illuminates to visually signal
automatic operation.
Note!
The commissioning process is now concluded.

Manual mode
Use:
For testing and maintenance tasks.
Start:
Press "Manual" on the controller. The Auto LED at the operator panel flashes to
visually indicate that Manual mode is active.
Functions:
Selecting the functions depends on the set make-up variant, "Levelcontrol" or
"Magcontrol".
Manual mode allows you to select the following functions and to perform a test
run:
•
Manual and deactivation of the "PU" pump with "Levelcontrol"
•
Manual switching on and off of the "PU" pump or "Filling" in the

"FIll" function.
–
"PU!" or "Fill!" is displayed to visually indicate that the
pump is being switched on.
3.
Press "OK" at the controller's operator panel to switch off the "PU" pump or
"FIll" function. Displays "PU" or "Fill" to visually indicate that the pump is
being switched off.
Note!
The controller calculates the pressure required for filling. As soon as this
value has been attained, the controller automatically stops the filling
process.
Note!
Manual operations cannot be performed if safety-relevant parameters
would be exceeded. Switching is then disabled.
8.1.3
Stop mode
Use:
For device commissioning
Start:
Press "Stop" on the controller. The Auto LED at the operator panel extinguishes.
Functions:
Except for the display of information, the device is non-functional in Stop mode.
Function monitoring is stopped.
•
The "PU" pump is switched off.
Note!
The system returns an alarm if the Stop mode is activated for more than
4 hours.
If "Floating alarm contact?" in the Customer menu is set to "Yes", the
system outputs the alarm to the group alarm contact.
8.1.4
Summer operation
Use:
The make-up with mains water must be ensured even when the heating and
cooling systems are not operating. Do not shut down the device when the
pressurisation of the heating and cooling systems are in operation.
