The pulses for the amount of heat flowing through are counted, 
e.g. 5 pulses within a minute. Through calibration via parameter 
12, the actual thermal output in kW is calculated.  

 

 

This function is only active if the charging pump function was 
assigned to one of the outputs "direct heating circuit pump", 
"variable output 1"or "variable output 2" in the "Hydraulics" menu. 

 

A charging pump to supply remote parts of the heating system is 
active at every heating or hot-water demand to the heat 
generator. It can be connected, through variable settings, at one 
of the variable outputs or at the direct circuit pump output. 

 

A charging pump connected to the central device under address 
10 will run as soon as any demand is present on the data bus 
(including all heating and hot-water circuits within the control 
network). 

A charging pump connected to an extension controller (address 
20, 30 ... 50) runs only on demand from the heating circuit 
associated with the respective control device. 

 

To avoid a high-temperature safety switch-off of the heat 
generator, a charging pump is switched off according to the set 
time delay when a request to the heat generator is withdrawn.
