ESA ESTRO - E7014P rev. 02 - 03/05/17
ESA ESTRO is a microprocessor operated flame control
device that controls gas and oil fired burners for conti-
nuous operation. This device safely controls one or two
stage burners (pilot and main), combustion air, and is
able to detect the flame signal via ionization sensors
(electrodes) or UV radiation (UV-scan), continuously per-
forming a periodic check of the flame sensor. The flame
control device is equipped with a serial communication
which allows remote burner control. The case is robust
allowing the application of the control device near the
burner.
APPLICATIONS
¾ One or two stage gas and oil burners (pilot or main),
with any type of capacity, with permanent or non-perma-
nent operation.
¾ Burners with electrode, unirod and UV detection (also
combined).
¾ Permanent operation by electrode detenction or by
UV scanner and shutter.
¾ Package burners with complete ignition cycle control
(blower, air regulation valve, pressure switch and air flow
switch).
F7014PI03
¾ Burners with air valve control for chamber purge, bur-
ner ignition and temperature regulation (heating/cooling)
via external regulator command.
¾ Plants with burner control via digital signals or ECS
serial communication.
¾ Personalized burner control via optional configuration
cards.
