the device can operate without any problem. In this case it
is highly advised to replace the current batteries with new
ones. The thermostat can still function with these batteries,
but it is much more error-prone.
NOTE: In case when communication is lost,
the receiver immediately switches off the heating.
After that, the heating can be turned on via the
mobile app by applying a set temperature higher
than 5.0 °C.
When the power supply comes back after the power
outage the receiver remains in its last state. If after
12 minutes the communication with the thermostat
is not established, it will turn off the heating. In this
case the heating can be turned on and controlled
only via mobile app by setting the set temperature
higher than 5.0 °C.
Freezing damage due to too low room temperature
If the room temperature is set too low in some rooms, the
heating system can be damaged due to freezing.
• Ensure that during the frost period the heating
system remains in operation and that all rooms during
your absence are sufficiently heated.
• The frost protection only activates when the thermostat
is turned off. Default frost protection temperature is 5 °C
and can be changed in the range from 0 to 17 °C. Frost
protection can be enabled or disabled via mobile app.
