18 SAFETY INTERLOCKS
The electronic control system of the BioClass iC 150 boiler may trigger the following safety interlocks to
stop the boiler's operation. When any of these interlocks occurs, the boiler stops working and an alarm
code appears on the display.
IMPORTANT: If any of the safety interlocks described below should occur repeatedly,
switch off the boiler and call your nearest official Technical Assistance
Service.
18.1 Temperature safety interlock
When this interlock occurs, the alarm code "E-11" will appear on the display. The burner will switch
off and stop heating the installation.
The interlock occurs whenever the water in the boiler exceeds a temperature of 100ºC. To unlock this
alarm, wait until the temperature drops to below 90ºC and press the button on the safety thermostat,
located on the underside of the boiler electrical box.
18.2 Safety interlock due to temperature in the fuel inlet pipe
When this interlock occurs, the alarm code "E-05" will appear on the display. The burner will switch
off and stop heating the installation.
The interlock will occur when the temperature of the fuel inlet pipe to the burner exceeds 80ºC. To
unlock the boiler operation, once the pipe temperature has dropped, press the reset button on the
safety thermostat (see figure) and press the RESET symbol on the boiler control panel to resume start
up.
