Checking the temperature sensor (Order No. 907 0 321):
If a temperature sensor is connected to input E1, and E1 is configured accordingly in the
application, the measured room temperature is transmitted by object 14.
A sensor break or short-circuit in the sensor line are reported by the value -60 °C.
Checking the window contacts:
If a window contact is connected to input E1, and E1 is configured accordingly in the application,
the window status is sent to the configured group address (object 14).
Also input E2 (object 16, condensation monitoring or window contact) can be checked.
Behaviour in delivery condition:
Before the application software is downloaded for the first time, inputs E1, E2 and the additional
relay C1 are connected via a common group address:
E1 = 7/4/100
E2 = 7/4/101
C1 = 7/4/100, 7/4/101
If the contact is connected to E1 or E2, the additional relay C1 is switched on.
This allows both inputs to be checked without bus monitor.
