7.3.4 Warning with high temperature
If temperature of the system increases to T≥85°C, the pump
works continually (due to taking heating energy through pipe
routing network), but measuring temperature indicator starts to
flash slowly (image 24). It is necessary to decrease
temperature to T≤84°C in order to stop automatic flashing of
warning indicator and continue with normal work of boiler.

high temperature value
If temperature of the system increases to T≥89°C, the pump
works continually (due to taking heating energy through pipe
routing network), but measuring temperature indicator starts to
flash quickly (image 25). It is necessary to decrease
temperature to T≤88°C in order to stop automatic flashing of
this mistake warning indicator.

of thermic overload, pump work continually
If temperature increases to T≥100 °C, display of its value is not
possible to see on the screen so in this will appear code EH
meaning that temperature is T≥100 °C (image 26). Measuring
temperature indicator will continue to flash quickly.

WARNING: Material damage due to
overheating
In this case it is necessary to turn off this device out of electric
power supply and call authorised service to establish and
remove the cause of problem.
If temperature sensor is damaged (or disconnected), the code
ES will appear on the screen meaning ''Error temperature
Sensor'' (image 27). Temperature measuring indicator will
continue to flash quickly.
