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.
