None
Always On
Purge
Lead On
None:
No Boiler Pump.
Always On:
Pump Runs Continuously.
Purge:
Pump Runs during pump pre/post purge operations and during call
for heat and then turns off.
Lead On:
Lead boiler’s pump runs continuously when the boiler is the lead
boiler and reverts to “Purge” operation when it is a lag boiler.
Pump
Prepurge
15
0 to 600 (s)
Sets length of time the boiler pump will be run prior to closing the “Call for Heat”
relay (CH).
Only visible when
Boiler Pump

None
.
Postpurge
Delta
5
0 to 20
(C or F)
Defines the temperature above BIT that BOT must be at or below before turning off
the boiler pump during pump post purge (Pump Cooldown State).

No
Yes
Enables the inlet temperature display and control logic.

No
Yes
Enables the mixing valve control output and user display.

Sets the time and date of the boiler’s real time clock. This item also displays the
time and date.

Sys Pump
FB
Low Fire
Sets the function of the Spare Input Terminal (SI).
Off:
Ignore.
Sys Pump Feedback: Input (SI) should be wired to a flow switch inserted in the flow
path of the primary system pump. Input (SI) indicates the
primary system pump is operating. If output (SP) is set to
System Backup Pump, system pump output (SP) is
energized and System pump Feedback is de-energized the
System Backup Pump output (SP) is energized.
Low Fire:
When the Fuel Valve Energized input (CS) is not energized
and Input (SI) is energized the modulation rate is set to the
“Low Fire Spd” setpoint. When input (SI) is not energized
the modulation rate is set to “Fan Purge Spd” setpoint.
When the fuel valve energized input (CS) is energized input
(SI) is ignored.
Fuel limit
Yes
No
Yes
Specifies whether high and low gas pressure switches are connected to input (GP).
Enables Fuel Limit Hold and alarm messages.

Soft Alarm
Sets the function of the Spare Output Terminal (SO).
Off:
Never close output (SO).
CAD:
Closes SO relay with a call for heat, Opens SO relay 2
minutes after call for heat has been de-activated.
System Pump BU:
Closes when System Pump output is activated but the
System Pump Feedback indicates the Primary System
Pump is not operating.
Soft Alarm:
Closes when a any alarm is active.
