Forced Operation Dependent Parameters; Cyclical Monitoring - ABB i-bus KNX Product Manual

ABB i-bus KNX
Parameters
7.8.1.1

Forced operation dependent parameters

The following parameters are available with forced operation activated. On the usage of the Forced
operation, 2 bit option, these parameters are available twice, once for the ON state and once for the OFF
state.
7.8.1.1.1 —
Dependent parameter
Control value / Control value for forced operation ON / Control value for forced operation OFF
Options:
This parameter is used to specify the control value that is to apply with forced operation active (for 2-bit in
the related state, ON or OFF).
The control value refers only to the valve for the currently active type of operation (heating or cooling).
7.8.2

Cyclical monitoring

Options:
The cyclical monitoring is used to monitor specific, selected group objects for the correct function of the
device. For each group object monitored it is possible to define a monitoring time during which the group
object monitored must be received.
If the group object is received in the defined time, the monitoring time starts again immediately after
the reception of the group object. If the group object is not received in this time, it can be specified how
the device is to behave.
•
Deactivated: The cyclical monitoring is deactivated.
•
Activated: The cyclical monitoring is activated. The dependent parameters for monitoring the individual
group objects are displayed. For each group object it is possible to decide separately whether it is to
be monitored or not.
For all cyclically monitored group objects it is important to set the behavior of the sending device
correctly. The group objects must be sent cyclically and the cycle time must be less (= more frequent)
than the receive time monitored.
Recommendation: Monitoring time = 2 × sending cycle time
Do not select times that are too low because this configuration can cause a high bus load and the
probability of an error increases.
