Air Flap Control For An Earth Collector - Program 8, 9 - Technische Alternative ESR 31 Mode D'emploi

Program 7
S1
min
diff
S2
max
The loading pump function has an additional threshold min2 via sensor S3 and tempera-
ture 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
A = ON
S1 max
A = OFF
S1 min
A = ON
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 max (regenera-
tion) and below the outside ambient temperature min (heating). S2 and S3 have no function.
Program 9
A = OFF
S1 max
A = ON
S1 min
A = OFF
The output switches when S1 < max and > min. Hence, while program 8 switches above
and below a temperature window, program 9 switches within a temperature window.
S3
Required settings :
min 2
max ... limit TK S2
min ... switch-on temp. energy generator 1 S1
diff 2 min2 ... switch-on temp. energy generator 2 S3
... energy generator 1 S1 – TK S2
diff
diff2 ... energy generator 2 S3 – TK S2
Required settings :
max ... upper switch-on threshold S1
min ... lower switch-on threshold S1
Required settings :
max ... upper limit S1
min ... lower limit S1
