second option enables a new 1-
bit object, “
[HCx] Unfreeze Alarm
”, which
should be used for externally unfreezing the alarm
once “
[HCx] Alarm
” has
received the no-alarm value (i.e., the inverse of the trigger value).
Note
:
the acknowledgement should be sent necessarily after “
[HCx] Alarm
”
has acquired the no-alarm value. Sending it while the trigger value is still active
will have no effect
.
Deactivation
– Action
: sets the state the output should acquire once the alarm
has been deactivated (and acknowledged, if required). The options depend on
the control method:

CYCLICAL MONITORING
It is possible to perform a
cyclical monitoring
of the control orders that are received
from the external device (e.g.: a thermostat) that controls this module, with the aim of
detecting communication issues.
This requires defining a
cyclical monitoring interval
, in other words, how frequently
these orders are expected to arrive from the bus. If this period is exceeded with no orders
received, a certain reaction will be performed and the error will be notified through a
specific object.
The
reaction in case of failure
can consist in:
Set the output status to a specific position.
Doing nothing.
