Comment
Temperatures
3TATUS
Current operating status of the boiler. Prepurge, Ignition, Name of the system Type being satisfied, post purge,
Warm Weather Shut down, Trouble
"OILER/UT
Temperature of the first sensing element of the boiler’s heat exchanger outlet sensor
"OILER/UT
Temperature of the second sensing element of the boiler’s heat exchanger outlet sensor
"OILER)N
Temperature of the boiler’s heat exchanger inlet sensor
3YSTEM3UPPLY
Temperature of the system water after the boiler loop
3YSTEM2ETURN
Temperature of the system water returning to the boiler loop
&ROM3ENSOR
Displays where System Supply/Return values are being read from. Most relevant when using multiple sensors connected
to the same Master Boiler Network. When Shadow boilers are connected, this will specify which boiler it is reading.
&LUE
Temperature of the first sensing element of the boiler’s flue gas sensor
&LUE
Temperature of the second sensing element of the boiler’s flue gas sensor
/UTDOOR
Temperature of the remote outdoor air temperature sensor
)NPUTS
3TATUS
Current operating status of the boiler. Prepurge, Ignition, Name of the system Type being satisfied, post purge,
Warm Weather Shut down, Trouble
)NPUT
Call for heat status on Input 1 (Input 1 can be TT1 or 0-10VDC input)
)NPUT
Call for heat status on Input 2
)NPUT
Call for heat status on Input 3
n6)NPUT
Voltage input for target adjust or modulation for single boiler
,INKEDTO-ASTER
For Multiple Boiler Networks. Shows if current control is connected to Master boiler
$EMANDOF-ASTER
For Multiple Boiler Networks. Shows if the Master boiler is calling this boiler heat demand
-ANUAL!UTO,IMIT
External manual limit on low voltage terminal strip (on left)
,OW7TR#UTOFF
Low water cutoff device (inside boiler jacket)
!IR03WITCH
Limit device (inside boiler jacket) that will shut off the boiler if flue pressure becomes too high
'AS03WITCH
Limit device that will shut off the boiler if gas pressure gets too high or low
#LOSURE3WITCH
P7 jumper circuit closed or open (flow switch, CAD, etc.)
"LOWER3PEED
Feedback from blower sensor
&LAME3IGNAL
Number indicating the presence and quality of the flame used to shut down or boost the boiler
Outputs
3TATUS
Current operating status of the boiler. Prepurge, Ignition, Name of the system Type being satisfied, post purge,

"LOWER3IGNAL
Control’s signal controlling the blower speed
!DDITIONAL(EAT$EMAND
Additional heat demand contact status
!LARM
Alarm contact status
n6/UTPUT
Voltage being output, by P16, pins 1 & 2
