Configuration parameters for firmware version 1.2 

The TCY-FT-U is preset to work for most applications. For special requirements it can be fine tuned to work ideally with a 
simple parameter setup routine. The parameters can be changed on the unit without the need of additional equipment.  

Identifying the firmware version 

The parameters and functionality of controller depend on its firmware version and revision. It is therefore important to use 
a matching product version and parameter set. The Firmware version and revision version can be found when pressing 
simultaneously the 

S

 and 

T

 keys during several seconds. On the upper 7 segment display, the firmware version can be 

found, on the lower 7 segment display the current revision index (or “sub-version”).  

Access to parameters 

The TCY-FT-U is an 

intelligent 

controller and can be adapted to fit perfectly into your application. The control operation is 

defined by parameters. The parameters are set during operation by using the standard operation terminal.  
The parameters are password protected. There are two levels of parameters: User operation parameters for access control 
settings and Expert parameters for control functions and unit setup. The passwords for user levels and expert levels are 
different. Only control experts should be given the control parameter password.  
The parameters can be changed as follows: 
 

1.

 

Press UP and DOWN button simultaneously for three seconds. The display will indicate the firmware version in the 
upper large digits and the revision in the lower small digits. Pressing any key will show: CODE. 

2.

 

Select a password using UP or DOWN buttons. Select 009 in order to get access to the user parameters, 241 for 
controls parameters.  
Press OPTION after selecting the correct password.  

3.

 

Once logged in, the parameter is displayed immediately 

4.

 

Select the parameters with the UP/DOWN keys. Change a parameter by pressing the OPTION key. The MIN and 
MAX symbols show up and indicate that the parameter may be modified now. Use UP and DOWN key to adjust 
the value. 

5.

 

After you are done, press OPTION or POWER in order to return to the parameter selection level.  

6.

 

Press the POWER key again so as to leave the menu. The unit will return to normal operation if no key is pressed 
for more than 5 minutes.
