AURATON S14 is a modern processor-based controller intended for work
also with forced-draught coal and fine coal fired boilers.
Depending on the temperature of water in the boiler, the controller
automatically starts or stops the water pump in the CH circuit with a coal-
fired boiler and the blower installed under the furnace.
The controller's digital sensor measures the temperature of the water in
the boiler and controls the pump and the blower based on the measured
values.
The
AURATON S14 controller also has the GUARD functions which
prevents stalling the rotor of the pump when it is not in use.
6.1. Installation
6.1.2. Mounting the sensor
In the controller, connect the temperature sensor to the SR1 terminals.
Then install the sensor on the boiler in the designated place.
The sensor must not be immersed in liquids or installed at the boiler
smoke outlets. The maximum measured temperature value is 99°C.
6.1.3. Connecting the power supply cable to the blower
In the controller, the blower's cable must be connected to the OUT5
terminal ( L , , N ). In the blower, connect the green or yellow-green wire
(grounding or zero) to the " " terminal, the blue wire - to the " N "
terminal, and the brown wire - to the " L " terminal.
6.1.1. Mounting the controller
The controller must be mounted on a wall or another support using two
screws (the concrete anchors with screws are delivered with the
controller). The cables extending from the controller must be fixed to the
wall with cable clips.
6.2. Operation of the controller
6.2.1. Switching the controller on
Set the power supply switch in the " I " position. After power is
switched on, all segments of the display light up and the software version
is shown for about 2 seconds. Then the controller indicates the current
temperature of measured by the
SR1 sensor.

6.2.2. Settings range
ź
The settings range is between 10°C and 85°C.,
ź
The operation time and interval between blow-throughs settings are
from 0 seconds to 99 minutes. ,
ź
The fan is controlled using the OUT5 output and the set temperature
refers to the temperature measured by the SR1 sensor (CH),
ź
The range of the hysteresis settings is between 2°C and 10°C (with a 2°C
increment).
6.2.3. Changing the temperature
Press the "
D
" button once for a short time. The set value --- °C (the fan is
switched off as a default) starts blinking. Then use the "+" or "-" buttons to
set the desired temperature value above which the fan will be switched
on and off periodically.
Once the desired temperature value is set, it must be confirmed (do not
forget to do so) within 10 seconds by pressing the "
OK " button.
Otherwise, the changed value will not be saved and the controller will
return to the previous setting.
6.2.4. Changing the operation time and the time of periodic
breaks in the fan's operation
Press the "
D
" button once. The fan temperature will start blinking. If you
press the "
D
" button again within 10 seconds, the controller will switch
to programming of the time of the fan's periodic operation (the blow-
through - the default value is 10 seconds). Then use the "+" or "-" button
to set the desired value (after 59 seconds, the time is automatically
displayed in minutes).
If you press the "
D
" button one more time within 10 seconds, you will be
able to set the time of the periodic break in the fan's operation (the time
between the subsequent blow-throughs - the default value is 5 minutes).
Then use the "+" or "-" button to set the desired value (if you go below
1 minute, the time is automatically displayed in seconds). Once the
desired value is set, it must be confirmed (do not forget to do so) within
10 seconds by pressing the "
OK " button. Otherwise, the changed
setting will not be saved and the controller will return to the previous
setting.
6.1.4. Connecting the controller
After the wires are secured to prevent accidental ripping, connect the
power supply cable on the side of the controller to the
IN terminals ( L , ,
N ). Then connect the cable to a 230V/50 Hz power outlet with a grounding
pin.
NOTE: The ambient temperature in the place where the controller
is installed must not exceed 40 °C.
NOTE: The wires and cables may be connected only when the
power supply is cut off.
