(only if heat balancing is activated)  

This set value allows choosing between volume flow computed in 

•  litres/minute for calculating the flow volume or 

•  litres/pulse when using the pulse input corresponding to the 

respective pumping capacity of the solar loading pump. 

 

With set value 0 L/min., no calculation of heat balancing is 
possible. 

 

(only if heat balancing is activated)  

This set value defines the fluid density of the heat carrier medium 
used according to the manufacturer data.  

 

Specific heat capacity medium (only if heat balancing is activated)  

This set value defines the specific heat capacity of the heat carrier 
medium used according to the manufacturer data. 

 

The physical values of volume flow, density and specific heat 
capacity form the basis for determining the solar heat balancing 
and the solar power and are calculated according to the 
mathematical relation 

W = (V/t) · ρ · cW · Δδ · tSOP  

    The results can be seen on the information level. 

W = Heat balancing 

V / t = Volume flow of the heat carrier medium 

ρ = Density of the heat carrier medium 

cW = Specific heat capacity of the heat carrier medium 

Δδ = Temperature differential (collector flow/return) 

 

This is an automatic function of the controller. If the solar loading 
pump was switched off longer than 24 hours, it is operated for 
approx. 20 seconds to prevent blocking via corrosion.  

 

This function is only active if a buffer loading pump is assigned to 
a programmable switching output or if a buffer sensor has been 
connected to a variable input.
