Configuration

The units can also be adjusted  
to requirements retroactively  
by adjusting DIP switch blocks  
1 to 3 accordingly. 
DIP switch block 1 configures  
unit-specific parameters and must 
be set in accordance with the 
table below. DIP switch block 2 
configures the network addresses 
within a bus and DIP switch block 3 
configures the unit's functions. 

Configuration is carried out using 
white slide switch SW1-4 for DIP1, 
SW1-6 for DIP2 and SW 1-8  
for DIP3. 
The following settings must be 
made according to usage before 
starting up for the first time.

Unit configuration (DIP1)

Adjusting this DIP switch provides 
the controller with specific key 
variables that are required  
for safe control behaviour  
and optimised unit operation.  
Only the configuration specified 
for the relevant unit is permitted 
to be used here, as this is the 
only way to guarantee optimised 
control behaviour. 

Network configuration (DIP2)

The addresses for the leading 
(master) and subsequent (slave) 
units are defined using switch 
block DIP2.

Function logic (DIP3)

The units can be used  
for numerous applications  
and requirements. The following 
settings are possible using switch 
block DIP3:

SW 1-3:  2- or 4- conductor function
SW 4:  Use of a valve
SW 5:   Fan function  

in the warm-up phase

SW 6:  Fan communication
SW 7:   Fan function in re-heat 

mode

SW 8:   internal/external controller
