4.1.13. Maximum store temperature
S MX / S1MX / S2MX:
Maximum store temp.
Adjustment range:
4 ... 95 °C
Factory setting: 60 °C
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 is reached at
the store. The symbols
are shown on the display.

Factory setting: 30 °C
and (both flashing)
pressed in order to confirm within 5 seconds
once again.
In order to cancel the RESET-operation, no but-
ton should be pressed for about 5 seconds. The
controller returns automatically into the indica-
ton mode.
Initially the controller works in the same way as
a standard differential controller. If the switch-
on difference (DT O / DT1O / DT2O / DT3O) 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 /
DT1S / DT2S / DT3S) is reached, the pump
speed is increased by one step (10%). If the
difference increases by 2 K (RIS / RIS1 / RIS2 /
RIS3), the pump speed is increased by 10 %
respectively until the maximum pump speed of
100 % is reached. The response of the control-
ler can be adapted by means of the parameter
„Raise". If the adjusted switch-off temperature
is underrun (DT F / DT1F / DT2F / DT3F), the
controller switches off.
If the adjusted maximum temperature is ex-
ceeded, 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 (flashing).
If the adjusted maximum
reached, solar loading is stopped in order to
avoid a harmful overheating of the swimming
pool. When the maximum temperature is ex-
ceeded, the display shows
