9.8 Locking sequences according to the outside
temperature
9.8.1 Purpose and activation
This function locks individual sequences depending on the outside temperature.
Purpose
This function is always active if an outside temperature value is available.
Activation
If other influences act on the sequence controller at the same time, the order of
priorities applies as shown in subsection 9.1.4 “Function priorities”.
9.8.2 Operating principle
You can lock heating sequences at high outside temperatures and cooling
sequences at low outside temperatures. This ensures that heating is deactivated in
summer and cooling is deactivated in winter. The switching differential is fixed at
2 K.

1 = sequence enabled
Explanation
0 = sequence disabled
If individual sequences are locked, the controller continues its action with the other
sequences without a transition.
Response if individual
sequences are disabled
If, for example, sequence 1 is locked, the controller uses sequence 2 for heating
(sequence 1 does not delay the control process).
