BlueHelix HiTech RRT H
Possible cause
Ionization electrode fault
Flame unstable
air/fume ducts obstructed
Trap blocked
Wrong calibration
Insufficient gas supply pressure
The fume probe detects an
excessive temperature
Sensor not correctly positioned
on flow pipe or damaged
No water circulation in the system Check the circulating pump
Air in the system
No water circulation in the system Check the circulating pump and heating system
Poor circulation and anomalous
flow probe temperature increase
blocked exchanger
Flow sensor damaged
No water circulation in the system Check the circulating pump and heating system

Cure
Check the position of the ionization electrode, free
it from any encrustations and do the Calibration
procedure [AUTO SETUP]. Replace the electrode
if necessary.
Check the burner
Remove the obstruction from the flue, fume extrac-
tion ducts, air inlet and terminals
Check the trap and clean it if necessary
Do the Calibration procedure [AUTO SETUP].
Check the gas supply pressure
Check the exchanger
Check the flue gas probe
Check the flue material parameter
Check the correct positioning and operation of the
heating sensor and replace it if necessary
Vent the system
Vent the system
check the exchanger and system
Check correct positioning and operation of the flow
sensor and replace it if necessary
Vent the system
Check the wiring or replace the sensor
Check the wiring or replace the sensor
check the wiring, or replace the valve
Check the wiring or replace the sensor
Check the wiring or replace the fume probe
See fault A07
Check the electrical system
Check the electrical system
Check if the parameter b04 is correctly configured
System pressure value outside set limits (transdu-
cer)
Fill the system
Check the water pressure switch
Reconnect the external probe or disable the sliding
temperature
Check and if necessary modify parameter b15 to 3
