Yes 
The consumer group is connected downstream from the primary controller / system 
pump. The primary controller ensures control of a valid heat or refrigeration request, or 
the system pump is activated. 
 
2-pipe system 
The Hx cooling circuit and the heating circuit obtain their cooling or heating energy 
from the same circuit
. 
4-pipe system 
The Hx cooling circuit and the heating circuit obtain their cooling or heating energy 
from separate circuits

The controller facilitates swimming pool heating with solar 
energy or a heat pump on the basis of separately adjustable 
setpoints. In the case of solar heating, it is possible to select 
priority of swimming pool heating over storage tank 
charging.

When using solar energy, the swimming pool is heated up until this setpoint is reached. 
The “Protective collector overtemperature” function can reactivate the collector pump 
until the maximum swimming pool temperature is reached.  
 
When using the heat source, the swimming pool is heated up until this setpoint is 
reached.

No 
Swimming pool heating through solar charging does not give consideration to any 
priorities. If storage tank charging priority (3822) is deactivated also, the swimming pool 
is heated alternately with the storage tanks, the temperature increase being 5 °C. 
Yes 
Swimming pool heating through solar charging is given priority. This also applies if 
storage tank charging priority (3822) would have to give preference to other heat 
exchangers.
