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.
