Key to Phases (Fig. 10, page 16):
Phase
Function
number
LOC Lockout shutdown phase
OFF Standby, waiting for heat request
oP Part 1: request load controller OPEN
Part 2: modulation of fan motor speed toward high-fire
Part 3: high-fire reached
Part 4: request load controller CLOSED
Part 5: modulation of fan motor speed toward low-fire
Part 6: low-fired reached
10 Settling time, fan motor standby speed
21 Safety valve ON, air pressure switch in no-load posi-
tion
Check if POC is closed, fan motor speed is reduced to
0
22 Part 1: fan motor ON
Part 2: specified time air pressure switch
Message (timeout), stabilization of air pressure switch
24 Settling time, fan motor prepurge speed
30 Part 1: prepurge time without flame simulation test
Part 2: prepurge time with flame simulation test
(2.1 seconds)
36 Speed settling time, fan motor ignition load speed
38 Preignition time
40 Postignition time, parameter 257 + 0.3 seconds
42 Flame detection
44 Interval: end of ignition safety time and release of load
controller
72 Speed stabilization time, fan motor postpurge speed
74 Part 1: operation is ended, check if postpurging is pro-
grammed
Part 2: postpurge time
80 Test space is evacuated
81 Atmospheric pressure test
82 Test space is filled
83 Gas pressure test
90 Pressure switch-min open --> safety shutdown
*1 Valve proving, if P241 = 1 after main ON, lockout or
P234 (postpurge time) = 0 second
*2 Valve proving, if P241 = 1 and P234 (postpurge time)
>0 second

Technical description of the burner
3.8.1
Both lockout reset button and signal lamp are located in the control
panel.
There are 2 diagnostics choices:

Visual diagnostics:
in normal operation, the different operating states are indicated in
the form of color codes according to the color code table given be-
low (Tab. L).
Indication of operating state
During startup, state indication takes place according to the Tab. L:
