Power failure
Following power failure, the controller will start operations depending on its status prior to the
occurrence of the power failure. The controller will wait for the period of one minute so that the electric
grid can stabilize, after which the operation with the previously programmed values of parameters will be
resumed.
5. TEMPERATURE LIMITER (STB)
The G-406-P11 controller has been equipped with additional mechanical protection, independent of
automatics, called the safety temperature limiter (STB).
Operation method:
Where the heating water has obtained the temperature of 95
0
C, the temperature limiter will be triggered
automatically (the STB function will be activated), the fan disconnected and the AL 5 alarm displayed on
the display.
When the temperature at the limiter drops down by some 20°C, the STB function may be manually
reactivated.
