NEO FIRE – Technical Manual

17.3

The boiler control unit and operating cycle

The control unit regulates:
The boiler operating cycle.
The boiler safeties (by indicating also the possible reasons for the boiler lockout).
The boiler power modulation.

Short description of the boiler operating cycle:

LEGEND of the operating phases:

Display

Meaning

Boiler in stand-by (the installation is not receiving any request of heat)

The boiler stops due to lack of gas pressure (minimum gas pressure switch)

Motor fan is activated (revolutions increase)

Start of the pre-venting phase

Time out (control of the fan speed)

Time of pre-ignition

Safety time of ignition and ionization control (constant)

Safety time of ignition and ionization control (variable)

Operation in the heating mode

Not available phase: D.H.W. operation
(according to the installation and to the boiler configuration)

Not available phase: Heating and D.H.W. operating in parallel
(according to the installation and to the boiler configuration)

20 / 21

Post air-venting and fan stop

Self-test and return to the initial position

Alarm / lockout (alarm code visualized on the display)
