Function 37 Modbus Mode
MODBUS MODE
OFF 37
Enables Modbus Mode on the
appliance. Factory Default: OFF
(Range: OFF, ON, AUTO). NOTE:
Turning Modbus Mode “ON” will open
a number of additional parameters
to customize Modbus installation.
See Modbus Instructions (lp-372) for
details. NOTE: Turning this Mode “ON”
without a connected and powered
Modbus communication adapter (p/n
7350P-629) will result in improper
appliance operation. Service calls
associated with this ARE NOT covered
by warranty.
Function 54
Boost Time
BOOST TIME
0 54
Temporarily overrides the Outdoor
Reset Curve to bring the boiler up to
the maximum setpoint to satisfy a
thermostat call in less time. Factory
Default: 0 min (Range: 0-762 min in
increments of 6 minutes.) EXAMPLE:
If 6 minutes is selected, and there has
been a call for heat for 6 minutes, the
boiler will override the Outdoor Reset
Curve and boost to the maximum
setpoint until the call for heat is
satisfied. The boiler will then continue
to boost for 6 additional minutes
before returning to the Outdoor Reset
Curve.
Function 55
CH Pump Priority
PUMP CH PRIO
OFF 55
Controls whether the CH pump will
operate during a DHW Priority call.
A setting of OFF will not run the CH
pump, while an ON setting will run the
CH pump. Factory Default: OFF (Range
OFF/ON)
Function 56
OA1 Configuration
O-10V A OUTPUT CONFIG
POWER BOIL 56
Controls the operation of the 0-10V A
output on the Field Connection Board.
Factory Default: BOIL POWER (Range:
BOIL POWER / CASC POWER / FAN
SPEED / ALARM / TEMPERATUR /
FLAME / DO NOT USE).
The following information details the 0-10V output parameters
described in Function 56 that can be read at a Building
Management System.
BOIL POWER - 0-10V output is proportional to boiler firing
rate. 0V = Not Firing, 1.5V = Minimum Firing Rate, 10V =
Maximum Firing Rate
CASC POWER - When configured on the Cascade Master,
0-10V is proportional to the firing rate of the Cascaded System.
0V = Not Firing, 1.5V = Minimum Firing Rate (One Boiler Lit),
10V = Maximum Firing Rate of all Connected Boilers
FAN SPEED - Output is proportional to boiler fan speed. 0V =
Fan is Off, 1.5V = Minimum Fan Speed, 10V = Maximum Fan
Speed
ALARM - 0V = Alarm is Off, 10V = Alarm is On
TEMPERATUR - Output follows boiler temperature setting
based on outdoor reset. 0V = Minimum Boiler Temperature

Function 57
OA1 Offset
O-10V A OUTPUT OFFSET
0.0 57
This value is added to the
OFFSTATE VOLT OA1 value, to
determine the total voltage output
required at the minimum case.
Function 58 OA2 Configuration
O-10V B OUTPUT CONFIG
POWER BOIL 56
Controls the operation of the 0-10V
B output on the Field Connection
Board. Factory Default: BOIL
POWER (Range: BOIL POWER
/ CASC POWER / FAN SPEED /
ALARM / TEMPERATUR / FLAME /
DO NOT USE).
Function 59
OA2 Offset
O-10V B OUTPUT OFFSET
0.0 57
This value is added to the
OFFSTATE VOLT OA1 value, to
determine the total voltage output
required at the minimum case.
Function 60
CH dT Setting
CH dT SETTING
20F 60
This parameter is only available
when DO NOT USE is selected in
Function 56. DO NOT USE THIS
PARAMETER. Return to Function
56 and select another parameter.
Function 61
Offstate Voltage OA1
OFFSTATE VOLT 0-10V A
0.0V 61
This parameter is only available
when DO NOT USE is selected in
Function 56. DO NOT USE THIS
PARAMETER. Return to Function
56 and select another parameter.
Function 62
Offstate Voltage OA2
OFFSTATE VOLT 0-10V B
0.0V 61
This parameter is only available
when DO NOT USE is selected in
Function 58. DO NOT USE THIS
PARAMETER. Return to Function
58 and select another parameter.
for Maximum Outdoor Temperature Setting. 10V = CH (or
cascade) temperature setting. This number will vary with the
outdoor temperature so that the user can know what setpoint
temperature the boiler is trying to achieve.
FLAME - Equals boiler Flame Current. 0V = 0ua, 10V = 10ua.
