•  Connection up to the stage of parameter 09 with minimum 

delay for hot-water loading 

•  In case of further need via heating, further connection with 

configured delay of parameter 02 

•  Reversion with configured delay parameter 03 

 

This function is only available, if a variable output is assigned to a 
circulation pump 

 

The output controls a hot-water circulation pump. 

 

The use of the economy interval minimises the usual circulation 
losses owing to adjustable switch-on intervals during operation 
and determines the standstill time of the hot-water circulation 
pump within an adjustable period (economy interval).  

 

This parameter determines the length of the period and hence the 
duration of the pause in a circulation pump pulse operating mode.

The switching-on degree is calculated from the ratio:  

n = Pulse time/Period duration x 100 (%) 

With an standstill time of 15 min. and a period of 20 min., the 
circulation pump will run for 5 min. before the subsequent pause 
of 15 min. 

The following is used to calculate the switching-on degree:  
n = 5/20 = 25% 

 

In this function a hot-water circulation pump can be coupled to an 
existing automatic program of a control circuit with regard to the
