Location can significantly affect the controller operation. Controller
located in a place with no air circulation or exposed to direct sunlight
may not work correctly. Install the controller on the internal wall of
the building (partition wall), in a place with air circulation. Avoid
installing it in the vicinity of heat generating devices (TV set, heater,
fridge) or in places exposed to direct sunlight. Installing the
controller near a door may also cause problems as the controller will
be exposed to vibrations.

If for any reason you want to have the temperature in
the room reduced by 3°C every day at the same time,
then you can do it for 6 hours. To reduce the
temperature:
1. Press the button and hold it for
3 seconds.
The display will show the symbol of
moon ( ) and the hour counter ( ).
2. The controller goes to the temporary
temperature reduction mode and
every day at the same time it will
reduce the temperature by 3°C for 6
hours.
2. Using the and buttons set the desired temperature
in the room with the 0.2°C accuracy.
3. Confirm your settings by briefly pressing the button.

The AURATON 3003 controller features a special FrostGuard
function which prevents freeze damage to your room. The function
is activated when the controller is off.
When the controller is off and the temperature in the room drops to
2°C, the display will show the symbols Fr ( ) and , and the
relay will activate. When the temperature rises to 2.2°C the display
will turn off again and the relay will disconnect the contacts.

FrostGuard function
NOTE: After 6 hours the controller will revert to the basic
temperature setting. On the display the moon symbol ( )
will be replaced by the sun symbol ( ).
NOTE: The temporary temperature reduction mode always starts
when the function is activated. This means that the possible
temporary temperature reduction should be programmed
at the time when you want the temperature change to
happen.
Switching off the temporary temperature reduction mode
To switch off the temporary temperature reduction mode, press and
hold this button for 3 seconds.
The display will show the current temperature in the room and the
controller will revert to the normal mode of operation.

Changing hysteresis
Hysteresis prevents the device from switching on too often due to
insignificant temperature fluctuation.
E.g. with HI2 hysteresis and temperature setting of 20°C, the boiler
switches on at 19.8°C and switches off at 20.2°C. With HI4 hysteresis
and temperature setting of 20°C, the boiler switches on at 19,6°C
and switches off at 20.4°C.
To change hysteresis, press ,
and simultaneously and
hold for 3 seconds. When hysteresis
change mode is active, message HI is
displayed.
Use and to change hysteresis settings.
HI 2 – ±0,2°C (factory setting)
HI 4 – ±0,4°C
HI P – PWM mode (see chapter “PWM mode”)
Press to confirm your selection.
The controller resumes normal operation.

You can switch on and off the controller any time by briefly
pressing the button.
The first pressing of any function button always turns the display
backlight on, only the second pressing activates a given
function.
During programming, failure to press any button for 10 seconds
is the same as pressing the button .
Notes
Pulse-Width Modulation mode (PWM)
When changing hysteresis settings, you can enable PWM mode.
In PWM mode, the controller switches on the heating device in
cycles to minimize temperature fluctuations. The controller
monitors the temperature rise and drop time.
Temperature
Time
Preset
temperature
Room
temperature
With these values determined, the controller switches the heating
device on and off in cycles that enable maintaining temperature as
close to the setpoint as possible.
CAUTION: In PWM mode, the controller can switch on the heating
device even though the temperature in the room is higher than
preset temperature. This is because the PWM algorithm tries to
maintain the preset temperature and stays ahead of the heating
system behaviour.
