Triggering:
For this, two digital inputs are defined as reference value increase and/or reference value reduction.
If the digital input is assigned to reference value increase and the input is short-circuited, the system reference
value increase is active.
If the digital input is assigned to reference value reduction and the input is short-circuited, the system reference
value reduction is active.
If several inputs are configured, the priority sequence is as follows: active before inactive before undefined.
In addition to the contacts, a reference value increase/reduction can also be triggered by the weather forecast
(e.g. a DHW reference value reduction is triggered once a particular global radiation value is reached).
Area of effect:
If a "System reference value increase" is active, this acts on each "consumer" (HC, DHW, PU) in the system in
heating mode that is configured for this, or in cooling more, if the "consumer" is configured for that. If several
inputs are allocated in a system and are active, these act in the same way as if there were only one.
If a "System reference value reduction" is active, this acts on each "consumer" (HC, PU) in the system in
heating mode that is configured for this, or in cooling more, if the "consumer" is configured for that. If several
inputs are allocated in a system and are active, these act in the same way as if there were only one.
A consumer is configured for increase / reduction if the corresponding parameter is not zero
Effect:
If an increase or reduction is active, the corresponding offset is allocated to the reference value in any event.
To achieve a reduction effectively, this means a negative offset must be set.
If both the reference value increase and the reference value reduction are active in a function, the two offsets are
added together. If one of the two functions (increase or reduction) collide with Smart Grid preferential operation,
the offsets are also added together and the Smart Grid forced acceptance has the higher priority.
