11.2.2 Troubleshooting
 If no aggregates are configured for the control sequences, the "Current setpoint"
is displayed as "---".
 When the commissioning menu is exited, a check is carried out to see if the
main controlled variable exists.
 If the main controlled variable or differential input is missing, the corresponding
universal controller is switched off and a fault message is triggered (see "Fault
messages").

3011 [Main contr var 1] sensor error
3012 [Main contr var 2] sensor error
3013 [Main contr var 3] sensor error
11.2.3 Control parameters (P-band, integral action time,
derivative action time)
For every sequence, a P-band (Xp), an integral action time (Tn), and a derivative
action time (Tv) can be set.
 Integral action time Tn = 00:00 m.s: The controller has no I-part (PD).
 Derivative action time Tn = 00:00 m.s: The controller has no D-part (PI).

11.2.4 Control timeout
You can enter a control timeout period, for example, to prevent the cooling valve
from opening immediately after the heating valve closes.
The controller does not add the integral action part during that period of time.
