High-efficiency pump
A high-efficiency pump can be connected to RO1 or 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 specification. For definition and settings,
the commissioning under
>0.7 Checklist<
has been provided.
Display
For indication of the operating mode and for communication in case
of set-up, malfunction, modification and evaluation, the SmartBio
is equipped with a coloured full graphics display which is perma-
nently backlit. The brightness of the backlighting can be adjusted in
steps of 10% from 10% to 100%. After a preset time backlighting is
dimmed. When a pump is activated, the pump-symbol flashes.

Additional heat source with delay function (DRD)
Function in Hydraulic systems 1.1, 1.2, 2.1 and 2.2.
SmartBio can activate immersion heaters or other heat sources if the
temperature in the primary 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 temperature 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 minutes (5°C x 20 min = 100) etc.
Hydraulic system 1.1 –
Primary heat source and Secondary tank
Hydraulic system 1.1 is intended for heating systems with a primary heat
source and a secondary tank. SmartBio controls the charge and return
pumps. When the primary heat source has reached the set tempera-
ture BT, charge pump RO1 starts transferring energy to the second-
ary tank. When the temperature TS1 in the primary heat source drops,
return pump RO2 starts transferring energy back to the primary heat
source. This return charging will continue as long as there is more en-
ergy 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 be-
tween the pumps. The fat arrow must point to the primary 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 sensor must not be placed on the supply pipe as this might dis-
turb the function.
Hydraulic system 1.2 – Solid fuel boiler with
thermic valve and storage tank
Hydraulic system 1.2 is intended for solid fuel boilers with a storage
tank and a LK 824 ThermoVar thermic valve with double-acting
check valve function. ThermoVar thermic valve ensures a high re-
turn temperature to the solid fuel boiler, thus increasing the ef-
ficiency of the system. Basic functions as in hydraulic system 1.1.
The pumps and the ThermoVar thermic valve are mounted between
boiler and tank according to the valve instruction.
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 find a required menu item, turn
the rotary encoder to “scroll” through the menu – the selectable option
appears on a coloured background on the display. To confirm the selected
menu item, press OK with the rotary encoder. An appropriate 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.
