  • Page 3 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.

  • Page 8 ESA ESTRO - E7014P rev. 02 - 03/05/17 DISPLAY AND LOCAL BUTTON SECTION DISPLAY ESA ESTRO displays different codes to indicate the flame control functioning and lockout statuses. Fixed symbols indicate normal operating conditions or certain non resettable faults, whilst lock or resettable fault con- ditions are indicated by flashing symbols.
  • Page 9 ESA ESTRO - E7014P rev. 02 - 03/05/17 DISPLAY STATUS DESCRIPTION Regime phase for ESA ESTRO-B with only 2nd stage burner on. The instru- FIXED ment intercepts the 1st stage solenoid valve. This phase occurs only when the “1st stage gas outlet type” parameter is programmed on “Interrupted”. Regime phase with air valve on.
  • Page 10 ESA ESTRO - E7014P rev. 02 - 03/05/17 DISPLAY STATUS DESCRIPTION Lockout due to the extended absence of serial commands by the remote super- FLASHING visor, for a longer period of time than the period programmed in the “Communication timeout” parameter. Malfunctioning is due to the presence of the air pressure switch signal before the instrument has activated the combustion blower.
  • Page 11 ESA ESTRO - E7014P rev. 02 - 03/05/17 DISPLAY STATUS DESCRIPTION Lockout due to an error in the internal memory reading. The failure can be tem- porary or final. The causes can be found in the incorrect connection to ground of the instrument or of the connected ignition devices, in the missing suppres- FLASHING sion filter in the ignition electrode connector, or else in the strong electromagne-...

  • Page 18 ESA ESTRO - E7014P rev. 02 - 03/05/17 PARAMETER VALUE DESCRIPTION N° NAME The instrument performs burner reignition (excluding prepurge) after the flame signal has disappeared. When burner ignition has taken place cor- Respark rectly, at the next flame extinction, the instrument performs another rei- gnition sequence.
  • Page 19 ESA ESTRO - E7014P rev. 02 - 03/05/17 PARAMETER VALUE DESCRIPTION N° NAME The instrument maintains the same behaviour as when “Discontinue Discontinue delayed 0 sec” is selected, with the difference being that from the valve closing command, it waits for 5 seconds before moving onto burner igni- delayed 5 sec tion, giving the valve time to close.
  • Page 20 ESA ESTRO - E7014P rev. 02 - 03/05/17 PARAMETER VALUE DESCRIPTION N° NAME The digital output indicates that the instrument is in lockout status, Stop / fault manual stop or waiting after power on (flashing display). The output is not activated during auto diagnosis.
  • Page 21 ESA ESTRO - E7014P rev. 02 - 03/05/17 PARAMETER VALUE DESCRIPTION N° NAME The instrument does not control the expansion cards. This configuration Inhibited is needed when the expansion cards are not installed or if the EXP-3 expansion is present. EXP Installed The instrument activates the expansion card control.
  • Page 22 Locked parameters PARAMETER VALUE DESCRIPTION N° NAME First safety time for ignition of the first gas stage (see table of allowed 1° safety time 1 ÷ 25 sec times). The 1st gas stage burner is kept running even after the ignition of the 2nd gas stage, until both are shut down at the same time.This configu- ration is valid for the single stage versions (ESTRO A2, C2 and Q2), or Intermittent...
