WARNING! If heating system is out of function
the freezing can occur

It is mandatory to secure the system

Empty the entire installation
WARNING: Material damage due to
freezing
7.3.3 Low temperature warning
If temperature of the system decreases to T≤4 °C, the boiler
continues to work normally, but measuring temperature
indicator starts to flash
slowly (image 21). It is necessary to
increase temperature to T
≥5 °C in order to stop automatic
flashing of warning indicator.
If temperature of the system decreases to T≤2 °C, all heaters
and pump will turn off (delays for 2 min), and temperature
measuring indicator will flash
quickly (image 22). With this
temperature value there is danger of freezing and boiler
damage, so the work of this device will be blocked. To continue
with boiler work it is necessary to increase temperature up to
T
≥5°C.
Present temperature displayed on the screen is possible for
values T
≥-9°C. Temperature below -9°C is not possible to be
displayed on the screen so the code EL will appear on display
meaning the temperature is below -9°C, or temperature
sensor is in circuit break (image 23
).
