Reading And Programming The Configuration Parameters - Carel heaterSteam User Manual

11.3 Reading and programming the configuration parameters

The configuration parameters are used to set the operating mode of the controller, that is to assign the humidifier's essential
functions.
The configuration parameters are divided into three groups:
Parameters for configuring standard operation (operating mode and types of probes), identified by codes from A0 to A9:
see Table 11.3.1.
Parameters for configuring the operation of accessory devices, identified by codes from b0 to b7: see Table 11.3.2.
Parameters for the setting the serial connections and remote control, identified by codes from C0 to C7: see Table
11.3.3.
These parameters can be accessed only by password to prevent the unwanted modification of the configuration.
