3. Control parameters and display channels
3.1.9 ∆T-regulation
DT O:
Switch-on temperature diff.
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
Please note: Switch-on temperature difference DO
must be at least 1 K higher than the switch-off tempe-
rature difference DF.
DT S:
Set temperature diffe-
rence
Adjustment range:
1,5..30,0 K
Factory setting: 10.0 K
RIS:
Rise
Adjustment range:
1 ... 20 K
Factory setting: 2 K
3.1.10 Maximum store temperature
S MX:
Maximum store temp.
Adjustment range: 2..95 °C
Factory setting: 60 °C
This function is a standard differential control. If the
switch-on differential is reached (DT O), the pump is
operated. The pump runs at 100% speed for 10 seconds.
After this period, the pump runs at minimum pump
speed (nMN = 30 %). If the temperature difference
reaches the adjusted set value (DT S), pump speed will
increase by one step (10%). If the difference increases by
2 K (RIS), pump speed will increase by 10 % respectively
until the maximum pump speed of 100 % is reached.
The response of the controller can be adapted via the
parameter „Rise". If the temperature difference falls
below the adjusted switch-off temperature difference
(DT F), the controller switches off.
If the adjusted maximum temperature is exceeded,
the store will no longer be loaded in order to avoid
damage caused by overheating. If the maximum store
temperature is exceeded,
Please note: The controller is equipped with a store
emergency shutdown function, which prevents the
store from being loaded when the store temperature
exceeds 95 °C.
