DHW Modulation Mode
This parameter controls
the boiler modulates for a DHW
demand. In NORMAL MOD mode,
the boiler will modulate down
from high fire when there is a DHW
demand. In LOW MOD mode, the
boiler will modulate up from low
fire when there is a DHW demand.
This mode is useful to minimize
short cycling when a large boiler
and small indirect tank are used
together. Factory Default: NORMAL
MOD (Range: NORMAL MOD / LOW
MOD).
Extra Heater Mode
Allows for a non Westinghouse
boiler to be controlled when the
cascade output has risen above the
percent of the cascade firing rate set
in this parameter. Factory Default:
Off (Range: 50% - 100%).
System Sensor Mode
Suppresses the 'NO FOLLOWER'
display message if the boiler is used
as a cascade master boiler with no
follower boilers connected. Factory
Default: OFF (Range: ON / OFF).
Service Schedule
Selects a service date or time based
on the boiler run hours to program
the boiler maintenance schedule.
Factory Default: OFF (Range: Date
or Run Hours). NOTE: Without
setting this function, Functions
33/34/35/36 will not display.
Modbus Mode
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.
