21HEAVY SECURITY PROTECTION MEASURES
√ Sanitary not water temperature limit protection
Qualified sanitary hot water temperature less than 60 degrees,in order to avoid water system fouling and high temperature hot water to the human body burns.
√ CB. Limit temperature protection
To prevent overheating,ensure safety,showing overheating fault code.
√ Water system over voltage protection
When the backwater heating system,more than 3 bar,the pressure telief valve will automatically open water,in order to protect the heating system.
√ Sanitary hot water flow protection
To prevent the bath water flow is too low,due to high temperature hot water burns to human body,only water flow reaches 2 l/min,to enable the function of bath.
√ IPX4 insulation protection
Under the condition of the environment is bad can be normal use.
√ Four minytes delay protection
After hanging furnace shut down,to prevent frequent start,guarantee the safe operation,unless the manual reset,cb or takes three minutes to start again.
√ Heating system voltage protection
Expansion tank can allevite fully heating water pressure due to thermal volume expansion and appreciation,have the effect of constant pressure system.
√ After scavenging function
When the eqyipment stop burning,fan after the furnce and local overheating,prolong the service life of the combustion chamber components.
√ Recovery manyally stop gas protection
The gas is interrupted,the machine automatically stop working,and after recovery ventilation machine can't start automatically,need to manually back to work.The function is safety design,user security,at the same time let the user self-check,found that the problem with property,contact the gas company.
√ Automatic power-off protection
Power,electric transmission,cb start automatically after the set up automatic work before power off.
√ Heating water temperature limit protection
When heating temperature reachea 80degrees,the limit temperature protection,the fire below the set temperature 25 degrees,restart the machine.
√ Low water pressure protection
Low pressure machine won't start,can be started only when the pressure is greater than 0.3bar heating system.
√ Prevent dry heating protection
When the system is water not free,automatic bypass valve will automatically open,ensure that the main heat exchanger with plenty of water,prevent dry.
√ Flame-out protection function
Electric ion flame control device,when the flame quenching,cut off the gas supply and display the fault code.To prevent the fire and incomplete combustion,locked-rotor too much electrcity burn out water pump.
√ The jammed protection
Circulating pump,every 24 hours start automatically run for 5minutes.
√ Frost protection
To protect domestic wall-mounted gas stove,when the wter temperature is less than 5degrees,circulating pump and heating burner to the system to start the water stop working until 15 degrees.
√ Voltage protection
Coltage above 242 v high voltage protection,low voltage 187 v low voltage protection,effectively protect machine main parts from damage.
√ Anti oxygen corrosion protection
Efficient automatic exhaust valve to ensure that in addition to the heating of the air in the water,making water oxygen levels to a minimum,to avoid oxidation system scalin,prolong the service life of the product.
√ Early scavenging function
Before gas lighting,fan of furnace purging,discharge residual gas combustion chamber to prevent ignition deflagration.
√ Air pressure protection
Power,electric transmission,cb start automatically after the set up automatic work before power off.
