9.2 Displaying Values on the Controller 
After the initial start and initialization phases are completed, the display value is determined by the parameter 
C0 (in case of remote operation OFF, there will simply be two dashes in the right two digits). 
Normally this is: 
•  The measurement from the main probe (stand-alone control). 
•  The % of steam production in appliances with slave control. 
The other values may be accessed by: 
•  pressing the SEL button. This displays the unit of measure of the value previously displayed. 
•  holding down the  button. This displays the measurement of the primary sensor, followed for 1 
second, by the unit of measure. This value can be observed with the sensor disconnected. 
•  holding down the  button. This displays the measurement of the secondary sensor, followed for 1 
second, by the unit of measure. This value can be observed with the sensor disconnected. 
•  In case of alarm, pressing the PRG button will reset the alarm message (assuming the cause of the 
alarm has been removed). 
To display the Set Point (main setting): 
•  Press the SEL button for around 2 seconds, until St appears. On releasing the button, the unit of 
measure of the Set Point is displayed for 1 second, and finally the current set value. 
It is also possible to access the functional parameters of the unit; these values control how the gaSteam 
operates. Follow the instructions in the appropriate section of this manual to change the parameters. 
9.3 Indication of an Alarm State 
In case of alarm status, the LED 9 begins to flash while the display indicates the code of the alarm 
alphanumerically in intervals of 2 seconds, displaying the value of the functional parameter that caused the 
alarm. 
In case of multiple alarms, the controller will display all applicable alarm codes in 2 second sequences. 
Simultaneously, the controller activates the alarm relay. For interpretation of the alarm codes see the 
maintenance section of this manual. The controller continuously displays the alarm, even if the reasons for the 
alarm have been removed, until reset by pressing the PRG button. If there are other alarm conditions they 
cannot be reset, the alarm will remain activated until they are fixed. 
Press for about 2
