Frost alarm
Temperature limit value for frost alarm
Options [°C]: – 2...10
(5)
Setting the temperature limit value. If the temperature falls below the limit
value, the
Control value (heating) when actual temperature is absent
or
in event of frost
is triggered and an alarm signal is sent via the EIB / KNX
(communication object “Temperature monitoring – Frost alarm error signal”).
Repetition of frost alarm
Options: –
no
repetition
–
cyclic repetition
Activation of the cyclic transmission function for the frost alarm.
If the option “cyclic repetition” is set, the object value is sent according
to the parameterised
Period for cyclical sending of frost alarm
.
Period for cyclical sending of frost alarm
Options [min.]: – 2...255
(5)
Setting of the cyclic transmission time for a frost alarm. This parameter is
only visible if the option “cyclic repetition” is set for the parameter
Repetition
of frost alarm
.
Variable temperature limit value monitoring
Maximum value
Options [°C]: – 2...10
(5)
Setting of the maximum permitted differential between the actual tempera-
ture and the setpoint temperature. When the maximum value is exceeded,
an error signal is sent via the EIB / KNX (communication object “Temperatu-
re monitoring – Temperature error signal (limit violation)”).
