If the thermostat function is supposed to run from 06:00 a.m. to 09:00 a.m. only,
adjust t1 O to 06:00 a.m. and t1 F to 09:00 a.m.
If the switch-on and switch-off times of a time frame are set to an identical value,
the time frame will be inactive.
If all time frames are set to 00:00, the thermostat function is solely temperature
dependent (factory setting).
Rapid heat-up
BOOS
Rapid heat-up runtime
Adjustment range: 0 … 120 min
Factory setting: 120 min
Adjustment of the maximum runtime for the rapid heat-up to be active.
Rapid heat-up enables immediate heating of the store even outside the adjusted
time frames.
If rapid heat-up is activated, the controller will switch on the backup heating of the
store. Rapid heat-up of the store will stop if the switch-off temperature BH F is
reached at sensor S3.
Î
In order to activate the rapid heat-up, scroll to the first display channel, press
and hold down button for 3 s. It is also possible to press the button of the
RCTT Remote control (accessory) instead.
3 s
Î
In order to deactivate the rapid heat-up, press and hold down the upper con-
troller button again for 3 s. It is also possible to press the button of the RCTT
Remote control again instead.
Note:
If the temperature at sensor S3 exceeds the adjusted switch-off temper-
ature BH F while rapid heat-up is being activated,
rapid heat-up
will be
blocked.
Drainback option
Note:
A drainback system requires additional components such as a holding
tank. The drainback option should only be activated if all components
required are properly installed.
In a drainback system, the heat transfer fluid will flow into a holding tank if solar
loading does not take place. The drainback option initiates the filling process if
solar loading is about to start. If the drainback option is activated, the following
adjustment can be made.
ODB
Drainback option
Adjustment range: OFF / ON
Factory setting: OFF
Note:
If the drainback option is activated, the cooling functions and the anti-
freeze function will not be available. If one or more than one of these
functions have 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:
If the drainback function
ODB
is activated, the factory settings of the pa-
rameters
nMN
,
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 will change. Adjustments previously made in these
channels will be overridden and have to be entered again if the drainback
option is deactivated later on.
