Collector minimum limitation:
Solar/Expert/Tcolmin
adjustment range: -25 ... 90 °C
factory setting: 10 °C
hysteresis 2 K
This is the minimum temperature which must be exceeded
for the solar pump to switch on. If the adjusted minimum
temperature is not exceeded or the condition “collector
blocked“ is fulfilled.
By means of this function, the respective store can be “re-
moved“ from solar control. This means that it is no longer
considered for solar loading.
The temperature of the store will be indicated but a sensor
defect will not be recognised.

If the adjusted switch-on difference
D
Ton between collector
and store is exceeded, the store will be loaded.
If this difference falls below the adjusted switch-off diffe-
rence
D
Toff, the loading function will be switched off.
Loading of the store will also be switched-off or suppressed
if the relevant store or collector is blocked (collector blo-
cked, see collector minimum limitation) or if the store is at
maximum limitation, e.g. Tstmax.
If the adjusted maximum temperature Tstmax is exeeded,
loading of the store is stopped. If the store cools down by
more than 2 K (hysteresis), the store will be loaded again.

store emergency shutdown
value 95 °C
hysteresis = 2 K
If the cooling options are activated (e.g. collector cooling),
the store will be loaded beyond the adjusted maximum
temperature.
In order to avoid too high temperatures in the store, the
emergency shutdown of the store is additionally provided,
which also blocks the store for the cooling options. If a
store reaches the temperature of 95 °C, the emergency
shutdown is activated
store blocked
A store is blocked if either the corresponding sensor is
defective or the emergency shutdown temperature has
been reached.
The parameter “
D
Tset“ is the nominal temperture diffe-
rence between collector and store used for pump speed
control. Once
D
Tset is reached, the pump speed is increased
by 10 %.
