4.1.9 Maximum store temperature
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 maxi-
mum store temperature is exceeded,
is shown on
the display (flashing).
Please note:
The controller is equipped with a se-
curity-switch-off of the store, which avoids a further
loading of the store if 95°C is reached at the store.
The symbols
and (both flashing) are shown on
the display.
4.1.10 ∆T-regulation (solid fuel boilders and
heat exchange)
Maximum temperature limitation
The controller is equipped with an independent
temperature differential regulation for which mini-
mum and maximum temperature limations as well
as corresponding switch-on and -off temperatures
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.
Minimum temperature limitation
When the adjusted value falls below MN3O , there-
lay will be deactivated. By exceeding parameter
MN3F
, the relay will be activated again. Parallely,
the switch on- and switch off temperaturedifferenc-
es
DT3O and DT3F apply for both: the maximum-
and minimum temperature limit.
Recommendation:
when using buffer tanks for
system 8, following adjustments should be made:
MX3O approx. 80°C/MX3F approx. 75°C.
Please note: the parameter MX3O and MX3F
always apply to the heat sink, the parameter MN3O
and
MN3F
to the heat source.
