Pause control
This function takes into account the actuation times of
valves and switches on the pump with a delay.
If the pause speed is activated, the relay of the store which
has been loaded last remains switched on during the loading
break time. Speed is determined by the value adjusted in
nLO.
If the pump delay is activated, the corresponding relay for
the valve will be energised fi rst. The pump(s) will be activa-
ted with the delay time (200s).

Adjustment range: 20 ... 90 K
Factory setting: 30 K
Spreaded loading option
(for PRIO 1, 2, Su 1 or Su 2 only)
Spreaded loading option OSE:
In 2-store systems with
2 pumps, a spreaded loading function can be activated.
As soon as the adjustable spread difference
DTSE
between
the collector and the priority store is reached, the second
store will be loaded in parallel unless it is blocked. If the
temperature difference falls by 2 K below
DTSE
, the pump
is switched off.
The collector temperature has to be higher than the store
temperature.

Note:
In systems with pump logic, the parameter
PDELA
is not available.
Drainback option
A drainback system permits the heat transfer fl uid to drain
back into the holding tank when solar energy is not coll-
ected. The drainback option will initiate the fi lling of the
system when solar loading begins. If the function is activated,
the menu items described in the following (
tDTO
,
tFLL
and tSTB) have to be adjusted:
Note:
The drainback option is only available in system
with one store and one collector fi eld and if no
cooling function is activated.
LLOGI / ODB
Drainback option
Selection: ON / OFF
Factory setting: OFF
Note:
A drainback system requires additional com-
ponents such as a holding tank. The drainback
option should only be activated if all components
required are properly installed.
Note:
If the drainback option ODB is activated, the
cooling functions and the antifreeze function will
not be available.
Note:
If the drainback option ODB is activated, the
factory settings of the parameters
DT O
,
DT F
and
DT S
will be adapted to values suiting
drainback systems. Additionally, the adjustment
range and the factory setting of the collector
emergency shutdown
CEM
will change.
Previous adjustments made in these channels
will be overridden and have to be entered again
if ODB is deactivated later on.
