After a certain time, for example one or several days,
a week, or a month, shortly press the
FILTER
button
again. The display will then show an integer number
of the hours during which the heating was switched
on (since the last reset). Comparison of the heating
duration with total time elapsed since the reset
allows for determining the ratio of real heating to idle
time of the heating device.
Maximal number of accounted hours amounts to
999. When the time measured exceeds 250 hours a
FILTER
indication starts blinking, thus reminding of
the need to check or reset the meter.
Once the meter achieves 999 hours it stops at this
value until resetting. The heating time may be
checked any time, similarly, the
FILTER
meter may
be in any time reset.
Note:
Is the heating operation time useless for the
user, simply ignore the
FILTER
button and indication
at the display.

controllers.
10. Controller sensitivity (hysteresis)
Sensitivity of the
AURATON 2020
and
AURATON
2020 TX RX Plus
controllers may be adjusted to 3
available levels: 0.5ºC (±0.25), 1ºC (±0.5), 2ºC (±1).
In the factory the sensitivity level is set to 1ºC. It
means that for the controller adjusted to 21ºC it
switches the heating device on for 20.5ºC and
switches it off for 21.5ºC. Should it be changed,
proceed as follows:
1
. Press the
RETURN
button and keeping it
simultaneously press
PROG
. The display
shows the indication SPA instead of the time,
and current sensitivity, e.g. 1ºC, instead of the
temperature.
2
. Using the buttons adjust the required
sensitivity, from 0.5ºC to 2ºC.
3
. Press
RETURN
or wait 10 seconds until normal
operation mode of the controller will be
resumed.
