10.4  H/C changeover 

10.4.1  Application and functions 

 

Use the heating/cooling changeover function block to change over the operating 
mode (heating or cooling) in 2-pipe systems. 

Application 

The preselection heating/cooling is generated on the device 

or

 received as a 

heating/cooling signal from the bus. 
 

23

 

 
The following types of changeover are available for H/C operating mode 
preselection: 

  Changeover with operating mode selector via operation. 

 Changeover by date. 

  Changeover with analog input (e.g. to change over by outside temperature or by 

flow temperature). 

  Changeover with digital input (e.g. to change over via manual switch or via 

changeover thermostat in the flow). 

 
 
If several changeover types are active, the operating mode is determined by the 
following priority selection: 
1. Operation 

selector

 

2.  H/C changeover input

 

3.  Heating/cooling acc to calendar

 

 
The preselected operating mode heating/cooling is provided in the heat and 
refrigeration distribution zone to all other controllers within the same zone. 

In a hydraulic circuit, the operating mode heating/cooling can be preselected only 
via one point. A fault message is generated, if several changeover signals are sent 
simultaneously to the bus within the same distribution zone. 
 
We recommend to enable preselected operating mode H/C at the primary 
controller or generation where possible. 

Recommendation 

 
 

10.4.2  Enable function "Heating/cooling changeover" 

 

To activate "Heating/cooling changeover", select "Yes" in operating line "2-pipe 
heating/cooling system".
