Time period - switch-on conditions
tDTO:
Time period -
switch-on conditions
Adjustment range: 1 ... 100 s
in steps of 1 s
Factory setting: 60 s
The parameter tDTO is used for adjusting the time period
during which the switch-on condition DT O must be per-
manentely fulfilled.
Filling time
tFLL:
Filling time
Adjustment range:
1.0 ... 30.0 min
in steps of 0.5 min
Factory setting: 5.0 min
The filling time can be adjusted using the parameter tFLL.
Stabilization
tSTB:
Stabilization
Adjustment range:
1.0 ... 15.0 min
in steps of 0.5 min
Factory setting: 2.0 min
The parameter tSTB is used for adjusting the time period
during which the switch-off condition DT F will be ignored
after the filling time has ended (Arr = 1 only).
Booster function option
OBST:
Booster function
Adjustment range: ON / OFF
Factory setting: OFF
This function is used for switching on a second pump when
filling the solar system. When solar loading starts, R2 is ener-
gized in parallel to R1. After the filling time (tFLL) has ended,
R2 is switched off.
Note:
The booster function is available in system layout 1
(Arr = 1) only.
The booster function will only be available if the
drainback option has been activated.
Drainback option
A drainback system permits the heat transfer fluid to drain
back into the holding tank when solar energy is not coll-
ected. The drainback option will initiate the filling of the
system when solar loading begins.
If the drainback option ODB is activated, the pump will
operate for the adjusted filling time tFLL in order to fill
the system with fluid from the holding tank. In system
layout 1, the switch-off conditions will then be ignored for
the stabilization time tSTB in order to avoid the system
from shutting down prematurely.
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
layouts 1 and 2.
ODB:
Drainback option
Adjustment range: OFF / ON
Factory setting: OFF
Note:
A drainback system layout requires additional
components such as a holding tank. The
drainback option should only be activated if all
components required are properly installed.
Note:
When the drainback option ODB is activated,
the cooling functions OCC, OSYC and OSTC
as well as the antifreeze function OCF are not
available.
If OCC, OSYC, OSTC or OCF have already
been activated before, they will be deactivated
again as soon as ODB is activated. They will
remain deactivated, even if ODB is deactivated
later on.
Note:
When the drainback option ODB is activated,
the temperature differences DT O and DT F
are set to a fixed adjustment. Additionally, the
adjustment range and the factory setting of the
collector emergency shutdown temperature
EM changes (see the corresponding channel
descriptions for further information).
Previous adjustments made in these channels will
be overridden and have to be entered again if
ODB is deactivated later on.
