17. Storage and transport conditions
The thermostat and radio module must not
be exposed to the direct influence of
atmospheric conditions, i.e. rain and sun
rays, and vibrations higher than typical
during road transport. Storage and transport
temperature should not exceed -10…60°C.
18. Description of possible faults
Symptoms
Tips
The thermostat
is not working.
The display
shows nothing.
Check the correct installation
of the battery - point 14.1 or
whether the batteries used are
not discharged.
The thermostat
is working but
there is no
backlight on
the display.
This is a normal phenomenon
that occurs with partially
discharged batteries. The
thermostat is still working
correctly. If the backlight is
required, replace the batteries
with new ones - point. 14.1
Buttons for
changing
settings do not
work.
Check if the buttons are not
blocked and if necessary
disable the child lock - point 9
(item 16).
The thermostat
does not start
the heating
mode.
The preset temperature may
be lower than the current room
temperature - increase the
preset temperature.
The radio
module can’t be
paired with a
thermostat or
several
thermostats.
The cause may be a lack of
coverage. For the time of
pairing with the radio module,
place the thermostat near this
radio module.
The battery in
the thermostat
is discharging
too quickly.
Check that the batteries used
comply with the
recommendations and are of
good quality. The cause may
also be frequent attempts to
connect the thermostat with
the radio module, eg during
longer interruptions in the
power supply of the main
controller.
