The position of the sensor in the buffer tank significantly affects the heat pump's control logic.
Upper position
It provides a view of the hottest zone of the tank and can be used for supply control.
Lower position
It shows more of the return status or the charge level of the tank.
Incorrect position
It can cause premature stops, delayed starts, or frequent cycling.
Correct choice
The manufacturer's specified sensor position and the specific hydraulic layout must be followed.
