If the output is deactivated (de-energised), the buffer is loaded 
(valve position A–AB, discharge deactivated). 
If the output is activated (energised), only the top region of the 
buffer is loaded (valve position B–AB, discharge activated) 

SDHPE: 5 K (fixed) 

Buffer setpoint  

Buffer setpoint +5 K 

 

The stages of the heat generator (then heating pump) should be 
able to switch off below a settable outside temperature. 

 

OFF, -20 – +30 

Special handling of heat generator version, setting 3: 

With a setting of heat generator type 3 (2x single-stage), special 
handling with regard to the outside temperature disable occurs so 
that a heating pump can be combined with supplemental heat 
generators. Below a set outside temperature, the heat pump (first 
heat generator) is then disabled, but the supplementary heater 
(second heat generator) remains enabled.  

•  If no "inverse outside temperature disable" was configured 

("Heat Generator" menu, parameter 38 = OFF), a configured 
"outside temperature disable" ("Heat Generator" menu, 
parameter 25) occurs on both heat generators. 

•  If an "inverse outside temperature disable" was configured 

("Heat Generator" menu, parameter 25 not OFF), the "inverse 
outside temperature disable" acts on the first heat generator 
(stage 1) and the "outside temperature disable" acts on the 
second heat generator (stage 2). 

 

A separate boiler sensor (BS2) must be configured for the second 
heat generator.
