18.2 Mode of operation
18.2.1 Sensor test
All temperature values measured can be displayed on operating line 141:
Code Sensor or unit
0 Outside sensor (terminal B9)
1 Flow temperature sensor (terminal B1)
2 D.h.w. temperature sensor (terminal B3)
3 Room unit sensor (terminal A6)
4 Primary return temperature sensor (terminal B7)
5 Multipurpose sensor (terminal B71)
Faults in the measuring circuits are indicated as follows:
--- = open-circuit or no sensor connected
ooo = short-circuit
18.2.2 Relay test
All relays can be manually energized on operating line 142, allowing their states to be
checked:
Code Response or current status
0 Normal operation (no test)
1 All relay contacts open
2 Relay contact at terminal Y1 closed
3 Relay contact at terminal Y2 closed
4 Relay contact at terminal Q1 closed
5 Relay contact at terminal Q3 / Y7 closed
6 Relay contact at terminal Y5 closed
7 Relay contact at terminal Y6 closed
8 Relay contact at terminal Q7 / Y8 closed
To terminate the relay test:
• Select another operating line
• Press one of the operating mode buttons
• Automatically after 8 minutes
With plant type no. 5, the relay test may be made only when the main shutoff valve is
fully closed!
Recommendation: When making the relay test, always close the main shutoff valve.
