Commissioning:
1. Connect all sensors and actuators (pumps, valves, auxiliary relays) to the con-
troller.
2. Establish the power supply of the controller.
3. During the initialization phase the operating control LED flashes red and green.
4. If failures occur after initialization phase (control lamp flashes, flashing symbols
in display), go to the Troubleshooting chapter of the controller manual.
5. When the controller is commissioned for the first time or is reset the com-
missioning menu starts.
1. Language
Adjust the desired menu language
dE : German
En : English
Fr : French
ÎChange to En.
2. Unit
Adjust the unit in which temperatures
and temperature differences are to be
displayed.
ÎChange to suit your needs.
3.Time
Adjust the clock time. First of all adjust
the hours, then the minutes.
ÎChange to local time.
4. System layout
Choose your system (detailed system
information on pages 4-7. )
Operating the commissioning menu:
Note:
This guide is for demonstration purposes only. Please read the mounting
and operating manual carefully before commissioning the controller and
pay attention to all safety advice and information. Wrong connection or
incorrect use can lead to damages to the device, the heating systems or
to persons.
