This function can only be called up, if a configurable switching 
output was occupied with a solid fuel loading pump. 

The following sensors can be used for control: 

•  SFS for the solid fuel boiler sensor  

The connection occurs automatically depending on the 
assignment of the output to VI1 or VI2. 

•  SFS for the solid fuel buffer sensor (optional)  

The connection occurs to variable input 1 – variable input 3 
depending on the assignment to an available variable input. 

•  If no solid fuel buffer sensor is connected, the collector 

tank/buffer sensor value (dedicated sensor input) is accepted 
as the buffer sensor. In this way, the collector tank/buffer 
sensor input can be used as a sensor input for several 
uncontrolled heat generators (e.g. solar or solid-fuel). 

 

 

A forced switch-on will be initiated for the solid fuel loading pump 
if a solid-fuel boiler sensor is defective. 

 

The solid-fuel function allows the integration of solid-fuel boilers 
(usually in combination with a buffer tank) into the system to 
support heating. Under this function the solid fuel loading pump 
can be controlled through various switching conditions as 
described in the following. 

 

If the temperature in the solid-fuel boiler rises 10 K above the set 
value, the solid-fuel loading pump is enabled.  

If the temperature in the solid-fuel boiler undershoots the 
minimum boiler temperature, the solid-fuel loading pump is 
switched off and loading is interrupted.
