value for the required temperature is then set below the
Correction
sign.
The example of
setting the room temperature to the fixed value of 25 °C is done in two steps:
1.
Room
= Set.
2.
Correction
= 25 °C.
Other parameters that can be set for any temperature sensor are:
Correction
(0 s, 0 °C)
– consists of two parameters. The first one is used to smooth
the jammed signal from the sensor by specifying filtering in seconds. The other one
can be used by the user to change the value given by the sensor and to adjust the
temperature deviation caused by, for example, the cable length.
Range
(–10 °C, 250 °C)
– determines the range over which the temperature of the
connected sensor can vary. Exceeding the limits can be signalled as an alarm. The
maximum range is -100 °C to 250 °C.
Value
( °C)
– indicates the temperature at the sensor location. If the temperature
value is less than -100 °C, then the supply cable has probably shorted or the
measuring cell itself has shorted. If the temperature is higher than 250 °C, then the
supply cable or the measuring cell itself has probably been broken. In the case of an
unstable value, a foreign signal is probably induced in the supply cable. A potential
fault is indicated by a bell on the LCD display or a flashing or lit alarm LED and a
message in the alarm list.
Pressure sensor
– by default it refers to the
AssignmentInputs/Outputs

menu. For the selected sensor, one of the inputs labelled according to the syntax described in
the previous section “Inputs and Outputs” is selected (e.g. for a supply air filter gauge
connected to the 3rd universal input of the second input extension
SupplyFilterAI
= 2X3
).
Another option is to set a constant pressure by setting the input to
Set
.
The required value for
the required pressure is then set under the
Correction
sign.
An example of setting the filter
pressure to a fixed value of 500 Pa is done in two steps:
1.
SupplyFilterAI
= Set.
2.
Correction
= 500 Pa.
Other parameters that can be set for any pressure sensor are:
