3.1.1 KEYS FUNCTION 

 

 

TEST: 

When

 

pushed for 3 sec. during normal operation, it activates the condensate drain.  

(Not used on No loss condensate drain)

 

 

SET: 

When pushed and released during normal operation, it displays the parameter C1. 

When  pushed  for  10  seconds,  it  allows  to  enter  the  C8  and  C9  condensate  drain  parameters  programming  menu  (see 
relevant table). 
When pushed after having set new configuration values, it stores the applied modifications. 

 

DOWN: 

When pushed while setting the drain set point, it decreases the displayed value of one unit per second, during the 

first 10 seconds, than of one unit every 0,1 sec. 
When pushed for 10 seconds during normal operation, it starts an automatic test cycle of the controller. 

 

UP: 

When pushed while setting the drain set point, it increases the displayed value of one unit per second, during the first 

10 seconds, than of one unit every 0,1 sec. 

 

ON / OFF: Pressed,

 it activates or deactivates the dryer. When the dryer is deactivated, the display shows OFF. 

 

NOTE:  when  the  controller is  in  the  OFF  position, some  parts  of  the  dryer may  still  be  energized.  Therefore,  for 
safety purposes, disconnect the electrical power before performing any operation on the machine. 
 

 

 
 
3.1.2 CONDENSATE DISCHARGE PARAMETERS PROGRAMMING 

 

 

 

Push the SET key for 10 seconds to enter the parameters configuration menu: the display will show in sequence the 
set point value, the code of the first modifiable parameter (C8) and its value). 
Only if strictly necessary, use the UP and/or DOWN keys to change the displayed parameter value. 
Press the SET key to store the previously changed parameter value or to browse the parameters without changing 
them. 
15 seconds after the last performed operation, the controller will return automatically to the normal operation mode.

NOTE: Changes entered for timing values will be effective only after exiting the programming, while changes to other variables 
will be immediately effective. 
Please remember that eventual changes to the configuration parameters of the machine could negatively affect its efficiency. 
Thus, changes have to be performed by a person familiar with the operation of the dryer.
