4.1.7
∆
T-adjustment
Please note:
Switch-on temperature difference DT O
must be at least 1 K higher than the switch-off temperature-
difference DT F.
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
4.1.8 Maximum store temperature
If the selected 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, is shown on the display.
Please note:
The controller is equipped with a safety-
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
Basically 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. If the selected switch-off
temperature is underrun (
DT F
), the controller switches
off.
