Table 6. TROUBLE-SHOOTING TABLE
Install the connecting piping strain-free to the boiler connections.
If the heating installation, including the piping network, has not been
built frost-proof, we recommend that you fill the heating installation
with a liquid which has low freezing point and corrosion protection and
antifreeze agent.
Boiler water too hot, heating bodies too cold
Make sure the circulation pump has been properly selected and the
heating installation is of the proper dimensions. (You must contact your
installer.)
Upon reaching a temperature of 95°С, the thermostatic safety protection
device is triggered and the fan is turned off. To resume protection,
remove the black cap on the front panel of the boiler and press the
button on the STB-thermostat. Contact your installer to determine the
cause of protection triggering.
Low boiler temperature.
Unable to reach normal temperature mode of 65°-85° С
