∆∆
∆T-regulation
Please note: Switch-on temperature difference DO must
be at least 1 K higher than the switch-off temperature-
difference DF.
DT O
:
Switch-on temperature
Adjustment range 1,0...20,0 K
Factory setting 6.0
DT F
:
Switch-off temperature diff.
Adjustment range
0,5 ... 19,5 K
Factory setting 4.0 K
4.1.9 Maximum store temperature
If the adjusted maximum temperature is exceeded, a
further loading of the store is stopped so that a damaging
overheating can be avoided. If the maximum store
temperature is exceeded, on the display is shown and .
Please note: The controller is equipped with a security-
switch-off of the store, which avoids a further loading of
the store if 95 °C are reached at the store.
S MX:
Maximum store temp.
Adjustment range 2..95 °C
Factory setting 60 °C
DT S
:
Nominal temperature
difference
Adjustment range 1,5..30,0 K
Factory setting 10.0
(PG 67.30 and 69.30)
RIS
:
Raise
Adjustment range 1 ... 20 K
Factory setting 2 K
(PG 67.30 and PG 69.30
)
Primarily the controller works in the same way as a standard
differential controller. If the switch-on difference (DT O) is
reached, the pump is activated and after having got an
impulse (10 s) a minimum pump speed (nMN = 30 %) is
run. If the adjusted nominal value of the temperature
difference (DT S)
(only PG 67.30 and PG 69.30
) is reached,
the pump speed is increased by one step (10%). If the
difference increases by 2 K (RIS)
(only PG 67.30 and PG
69.30
), the pump speed is increased by 10 % respectively
until the maximum pump speed of 100 % is reached. The
response of the controller can be adapted by means of the
parameter „Anstieg“ (raise). If the adjusted switch-off
temperature is underrun (DT F), the controller switches-
off.
