Duct humidistat TDC-BH-U-W24
Configuration parameters
The TDC-BH-U can be adapted to wide variety of applications. The adaptation is done with parameters. 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 revision. It is therefore important to use
a matching product version and parameter set. The firmware version is marked on the package box of your
product. In order to identify the firmware version of an installed controller, press UP and DOWN keys
simultaneously for three seconds: The display will indicate the firmware version in the upper large digits and
the revision in the lower small digits. Press the LEFT key to return to normal operation.
Setting of user parameters
The TDC-BH-U 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 control buttons.
The parameters may only be accessed by entering a code. There are two levels of parameters: User
operation parameters for access control settings, and Expert parameters for control functions and unit setup.
The codes for user levels and expert levels are different. Only control experts should be given the control
parameter code.
The parameters can be changed as follows:
1.
Press UP and DOWN button simultaneously for three seconds. The display shows the software
version in the large digits and the product code in the small digits.
2.
Pressing the OPTION button will indicate CODE on the small digits and 000 on the large digits.
3.
The code for accessing the user parameters is 009
4.
Select this using UP or DOWN buttons.
5.
Press OPTION button after selecting the correct code.
6.
Once logged in, the parameter is displayed immediately.
7.
Select the parameters with the UP/DOWN buttons. Change a parameter by pressing the OPTION
button. Three triangles will show up on the lower right and indicate that the parameter may be
modified now. Use UP or DOWN buttons to adjust the value.
8.
After you are done, press OPTION or POWER in order to return to the parameter selection level.
Press the POWER button again so as to leave the menu. The unit will return to normal operation if no button
is pressed for more than 5 minutes.
