Function
Standby
OFF Standby, waiting for heat request
Ph08 Power ON / test phase (e.g. detector test)
Startup
Ph21 Safety valve ON, air pressure switch test / POC test (timeout / locking after 5 seconds),
actuator opens in low-fire position / CLOSE position
Ph22 Fan motor ON and air pressure switch test / settling time
Ph24 Actuator travels to the prepurge position
Ph30 Prepurging
Ph36 Actuator closes until ignition load / low-fire is reached, and
parameter 259.02: Actuator opens to a position > ignition load
Ph38 Preignition
Ph40 1st safety time / ignition transformer ON
Ph42 Safety time (ignition transformer OFF), flame check
Ph44 Interval: End of safety time and fuel valve 1 ON
Interval: End of safety time and load controller release
Interval: End of safety time and fuel valve 2 ON
Ph50 2nd safety time
Ph54 Parameter 259.01: Actuator opens to a position > low-fire
Ph54 Parameter 260: Actuator closes until low-fire position is reached
oP:P1 Interval to release of preset load controller (analog or 3-position step input)
Operation
oP:xx Operation, modulating operation
oP:P1 Operation first stage
oP:P2 Operation second stage
Shutdown
Ph10 Actuator travels to the CLOSED position (home run)
Ph72 Actuator opens until high-fire position / operation shutdown is reached
Ph74 Postpurging
Valve proving
Ph80 Test space evacuating
Ph81 Test atmospheric pressure
Ph82 Test space filling
Ph83 Test gas pressure
Waiting phases (start prevention)
Ph01 Undervoltage / overvoltage
Ph02 Safety shutdown, followed by a non-alterable lockout with interlocking
↑ e.g. safety loop open
Ph04 Extraneous light on burner startup (timeout / locking after 30 seconds)
Ph90 Pressure switch-min open
↑ safety shutdown / non-alterable lockout with interlocking
Non-alterable lockout
