Adjustment channels
4.1.9 ∆T-regulation
DT O / DT1O / DT2O /
DT3O:
Switch-on temperature
Adjustment range:
1.0 ... 20.0 K
Factory setting: 6.0
DT F / DT1F / DT2F / DT3F:
Switch-off temperature
difference
Adjustment range:
0.5 ... 19.5 K
Factory setting: 4.0 K
Please note: Switch-on temperature difference
DO must be at least 0,5 K higher than the switch-
off tempe rature difference DF.
DT S / DT1S / DT2S
/ DT3S:
Nominal temperature
difference
Adjustment range:
1.5 ... 30.0 K
Factory setting: 10.0 K
RIS / RIS1 / RIS2 / RIS3:
Raise
Adjustment range:
1 ... 20 K
Factory setting: 2 K
4.1.10 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.
4.1.11 Store maximum limitation - swimming pool
SPMX (Arr 10 only):
Swimming pool
Setting range: 4 ... 95 °C
Factory setting: 30 °C
4.1.12 ∆T-regulation (solid fuel boilders and heat exchange)
Maximum temperature limitation
MX3O / MX3F:
Maximum temperature
limitation
Adjustment range:
0.5/0.0 ... 95.0/94.5 °C
Factory setting:
MX3O 60,0 °C
MX3F 58,0 °C
and (both fl ashing)
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 controller
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
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 (fl ashing).
If the adjusted maximum temperature is rea-
ched, solar loading is stopped in order to avoid
a harmful overheating of the swimming pool.
When the maximum temperature is exceeded,
the display shows (fl ashing).
The controller is equipped with an independent
tempe rature differential regulation for which mi-
nimum and maximum temperature limations as
well as corresponding switch-on and -off tempe-
ratures can be separately adjusted. Only possible
for Arr = 2 and 8 (e.g. for solid fuel boilers or
heat exchange regulation).
Is the adjusted value MX3O exceeded, the relay
2 will be deactivated. By falling below MX3F, the
relay will be switched on again.
