or OFF. Telegrams are not triggered in
this case.
No further evaluation of the limiting
values takes place during the active
frost/heat protection mode. The limiting
values are first evaluated and updated
again after changing to another
operating mode (comfort, standby or
night mode).
If the controller is in the frost/heat
protection operating mode and the
operating mode changes from heating to
cooling or vice versa, then the
parameterised behaviour of the limiting
values is executed according to the
current operating mode of the controller.
The cyclical transmission of the limiting
values of the measured values is not
influenced.

With "No" no external limiting value is
configured.
With "Absolute value via 2-byte object"
the limiting value is predefined via a
2-byte value object.
With "Percentage via 1-byte object" the
limiting value is predefined via a 1-byte
value object.
When using the external switching
object "Store limiting value via switching
object", the current measured value of
the sensor can be defined as limiting
value.
