AURATON 3003, Руководство пользователя, Страница: 14 / 20

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.
