Loading pump control - program 4
The loading pump runs when S1 has exceeded the threshold min, the temperature of S1
is diff higher than S2, and S2 has not yet crossed the threshold max.
Program 5
6
The loading pump function has an additional storage limiter max2 via sensor S3.
Program 6
The loading pump function has an additional threshold min2 via sensor S3 and temperature
difference diff2 between S3 and S2. Hence, the system can be switched off via two
energy generators (S1 and/or S3).
Air flap control for an earth collector - program 8
The output switches when S1 < max or > min. An air/water heat pump thus has a flap for
the airflow from the earth collector above the outside ambient temperature min (regeneration)
and below the outside ambient temperature max (heating). S2 and S3 have no function.
Program 9
The output switches when S1 > max or < min. Hence, while program 8 switches above
and below a temperature window, program 9 switches within a temperature window.
