Learning Function
This function starts only if the thermostat has no floor
sensor connected, (‘Er3’ indicated briefly at start-up) only
in ambient sensing mode configuration.
At the first thermostat power-up (or after a factory
reset), the thermostat begins its own regulation
parameter calibration.
During this learning time, the user doesn’t have
access to ambient temperature:
Instead of temperature, a count down timer
from 2.1 hours to 0.1 hour
(0.1 hour = 6 minutes) is displayed.
The learning time is divided into two steps:
1. Time < 30min (0.5 hour) [ from 2.1h to 1.6h]:
the first half hour, the user is allowed to change
the set temperature and activate the floor warming
system. This period can be used by the installer to
check the floor warming system installation.
The set temperature can be adjusted by using
<
> keys.
2. 30min < Time < 2hours [from1.6h to 0.1h]:
The thermostat doesn’t take into account the set
temperature. But during this period, the thermostat
can power on and off the floor warming system to
adjust its regulation parameters.
If there is a main power supply loss during this learning
period (main switch off or power supply failure), the
thermostat will restart the learning function.
At the end of this learning function, the thermostat is
automatically calibrated (adapted to the load linked
to the thermostat):
