INFORMATION
Marked parameters of the list above are not used on BAF units.
5.3. Setting the operating mode
The controller can use 2 different types of input, mutually exclusive and that are selected with
parameter
, Control type.
= tPr: Temperature control, with up to 3 temperature probes, NTC 10K type at 25°C;
= PrS: Pressure control, with an input of 4-20mA type, connected to the pressure transducer.
INFORMATION
When the control type is selected, only the sensors assigned to it are taken into account. For
example, a connected pressure probe is not considered in the temperature control mode.
The probe value is displayed only if the probe is connected. If the probe is not used and not
connected, “nu” (not used) label appears on the display.
