High-efficiency pump
A high-effi ciency pump can be connected to RO1 or/and
RO2. The appropriate control signal is issued at TS4. The
control signal may be an analog voltage 0 – 10 V or a PWM-
signal. For further details, please refer to the pump specifi -
cation. For defi nition and settings, the commissioning under
has been provided.

Display
For indication of the operating mode and for communication
during set-up, messages, modifi cation and evaluation, the
SmartBio is equipped with a coloured full graphics display
which is permanently backlit. The brightness of the backlight-
ing can be adjusted in steps of 5% from 10% to 100%. After a
preset time (30 - 255 sec) backlighting is dimmed.

Operation
The entire set-up and operation of the SmartBio are effected via two
control knobs on the controller front. All settings and interrogations
are effected via the rotary encoder. To fi nd a required menu item, turn
the rotary encoder to "scroll" through the menu – the selectable op-
tion appears on a coloured background on the display. To confi rm the

selected menu item, press OK with the rotary encoder. An appropri-
ate submenu is called up or the selection is activated. Press the ESC–
button to make the menu return by one level. If no input is made
within the preset time, the controller will automatically return to the
hydraulic system.
Additional heat source with delay function (DRD)
Function in Hydraulic systems 1.1, 1.2, 2.1 and 2.2.
The green sym-
bol f indicates
the remaining
delay (DRD).
SmartBio can activate immersion heaters or other heat sources
if the temperature in a tank falls below the set value. To avoid
unnecessary starts the additional heat source has an adjustable
delay function. The delay can be set between 0 and 100 degree
minutes. With the setting 0 the additional heat source will start
as soon the temperature is below set value. With the setting 50
it starts with a delay as follows. If the temperature falls 10°C it
starts after 5 minutes (10°C x 5 min = 50 degree minutes). With
the setting 100 the additional heat starts as follows. If the tem-
perature falls 10°C it starts after 10 minutes (10°C x 10 min = 100
degree minutes). If the temperature falls 5°C it starts after 20 min-
utes (5°C x 20 min = 100) etc.
Hydraulic system 1.1 –
Primary heat source/tank and Secondary tank
Hydraulic system 1.1 is intended for heating systems with a primary
heat source/tank and a secondary tank. Heating water and domestic
hot water are taken from the primary heat source. SmartBio controls
the charge and return pumps. When the primary heat source has
reached the set temperature BT, charge pump RO1 starts transferring
energy to the secondary tank. When the temperature TS1 in the pri-
mary heat source drops, return pump RO2 starts transferring energy
back to the primary heat source. This will continue as long as there is
more energy in the secondary tank.
If the temperature TS1 in the primary heat source drops below the set
temperature RA, the additional heat source starts with selected delay.
Normally charge pump RO1 is not activated at this point. However
the pump can be activated in commissioning. The additional heat
source is activated until the set temperature RO has been reached.
The pumps and the ThermoBac DB check valve are mounted in
the return-pipe between primary heat source and secondary tank.
The check valve which prevents self-circulation in both directions is
mounted between the pumps. The fat arrow must point to the pri-
mary heat source.
Sensor TS1 is mounted in a sensor pocket in the upper part of the
primary heat source. Sensor TS2 is mounted in a sensor housing in
the upper part of the secondary tank.
Sensor TS3 is mounted in the lower part of the secondary tank.
N.B! The sensors must not be placed on the supply pipe as this might
disturb the function.
