During this time, if the appliance perceives flame existence, then it moves to
<PRE-OPERATION>
phase.
Otherwise
, startup is being terminated and
error E20
appears on the
screen.
The appliance perceives the existence of flame if there is fume temperature increase.
<PRE-OPERATION>
During this phase the preparation of flame occurs, so that in the next phase which is
<OPERATION>
phase, the flame will be satisfactory. Moreover, during this phase the
initial stock, created for the ignition, is being burned. Ignition resistance is disabled.
<OPERATION>
Automatically
During this phase the boiler operates with the control system enabled. The speed of the power supplies and the combustion fans are adjusted automatically, in order to
achieve the
desirable operation temperature.
Manually
When a manual program has been selected, then the control system
is not enabled
. On the contrary, it operates according to the selected power scale
constantly
.
The power value for each scale is regulated by the settings:
“
Power scale
1”
for scale 1
“
Power scale
2”
for scale 2
“
Power scale
3”
for scale 3
The appliance uses this value to define the current values of combustion fans and power supplies.
<REGULAR CLEANING>
As long as the appliance functions with low power, due to low air flow in the combustion chamber and low temperature, there is cleaning problem.
<REGULAR CLEANING>
is
a protection measure. The control system enters this phase periodically, while being in
<OPERATION>
phase, and it remains in this phase for a few seconds. The combustion
fan operates, while the supplier is disabled.
