Threshold switch
The evaluation unit threshold switchis a separate unit, independent of the meteorological data. Four
independent channels with two telegrams per channel are available.
Principle:
A value is received via the bus. It is compared with the defined threshold. If the value is greater than the
defined threshold the condition is met, otherwise the condition is not met.
Logic module
The evaluation unit “logic module” is a separate unit, independent of the meteorological data. Six inde-
pendent channels with two telegrams per channel are available. Therefore the logic modules can fulfill
various tasks within a KNX installation.
Principle:
Up to four 1 bit input values can be linked via a logical operation.
The following input values can be selected:
input objects of the logical modules
status of the sensor evaluations (condition met/ condition not met)
status of the threshold switches (exceeded/ underrun)
operation result of the other logical modules (a logic module cannot be linked with itself)
