Configuration settings are presented for changing in the following order:
To enter the configuration settings change mode press the‚
buttons
simultaneously and hold them for 5 seconds until the display backlight starts
flashing.

.
HYSTERESIS CHANGE
:
Hysteresis is designed to prevent switching the controlled device on and off
too frequently due to minute fluctuations of temperature.
E.g. for the
HI 2
hysteresis, when the temperature is set to 20°C, the boiler
will be switched on at 19.8°C, and switched off at 20.2°C. For the HI 4
hysteresis, when the temperature is set to 20°C, the boiler will be switched
on at 19.6°C, and switched off at 20.4°C.
The hysteresis change mode is signalled by
flashing text
HI
. You can change hysteresis
settings with turn the knob clockwise.

.
OFFSET CHANGE
Offset allows for calibrating temperature indications within the tolerance
of ±3°C.
E.g. the temperature regulator indicates that the room temperature is 23°C,
whereas a regular mercurial thermometer placed alongside indicates 24°C.
Changing offset by +1 degree makes the regulator indicate the same
temperature as the mercurial one.
The offset change mode is signalled by flashing text
OFFS
. You can set the desired value (turn the knob
clockwise) within the range from 3.0 to 3.0
(factory
setting is 0.0)
.
Confirm the setting by pressing the
button. The regulator will resume
normal mode of operation.
[OK]
NOTE:
If no button is pressed for 10 s while changing configuration settings,
the regulator will resume normal mode of operation.

.
DELAY CHANGE
(AURATON 3021 / 3021 DS only)
Delay is designed to prevent switching the controlled device on and off too
frequently e.g. due to a momentary whiff of air caused by opening
a window.
This mode is signalled by flashing text
90:SE
. Turn the knob clockwise to
switch the delay on and off.
90:SE
– 90s delay
(factory setting)
0:SE
–
without delay.
Confirm the setting by pressing the
button. The regulator will proceed
to change the next parameter.
