Description
Select the function of an ordinary measuring sensor, light sensor, wind or tempe-
rature sensor. Basically, all functions operate in the same way.
When the channel or flag entered here is activated, all switching operations of the
sensor are disabled.
The value can be overwritten at any time and deleted by the Delete-key.
This entry is needed in order to use the sensor to activate a relay coded to the
same address.
If the analog value is to be displayed on this channel (for instance on a Touch-
screen), then this option must not be selected.
This option inverts the switching function in relation to the limit values.
When selecting this option, the analog value is provided by another channel. The
channel to provide the alternative analog value is entered in the field "Measuring
channel".
The upper and lower limit values of the sensor. For example, the lower value
could be -30 ˚C, while the upper value could be 60 ˚C.
Note: The entry of each value must be confirmed with the Enter-key.
If the sensor providing the value is coded for another channel, this "source chan-
nel " is entered here. For this purpose, the option "Alternative input" must be acti-
vated. The value can be overwritten at any time and deleted again by the Delete-
key.
These are the switching limits of the sensor object. If the option "Invert limits" is
not selected, the limit values appear as described, ie if the values "17.0" and
"20.0" are entered, the channel switches off when the actual value is below 17.0
and switches on when the actual value is above 20.0.
When the limit values are inverted, the sensor switches on when the actual value
is below 17.0 and switches off when the actual value is above 20.0. This setting is
typical for a heating control system.
The limit values are only active, when the address enabling a second pair of limit
values is not switched on.
Note: The entry of each value must be confirmed with the Enter-key.
This option is selected in order to enter a second pair of limit values, for instance
for night setback.
The second pair of limit values makes it possible to enable a different switching
operation through a different address - "Enabled by address". If "Enabled by
address" is activated, the second pair of limit values will apply in stead of the first
pair.
The second pair of limit values can also be inverted by the "Invert limits" option.
Note: The entry of each value must be confirmed with the Enter-key.
When the selected channel or flag is not active, the first pair of limit values will
apply, when it is active, the second pair will apply.
The value can be overwritten at any time and deleted by the Delete-key.
