Allows the user to program the boiler
supply water temperature to the
indirect heat exchanger during a
o
demand cycle. Default: 180
F (Range:
o
o
119
F to 190
F).
Water Safety Input
The user can select various water
safety inputs used in the boiler system.
Default: Flow Switch (Range: None
/ Low Water Cut Off / Flow Switch /
Water Pressure).
Error Outdoor Sensor
Allows the user to set the control to
display an error message if an outdoor
sensor is open or shorted. NOTE: This
error does not stop the boiler from
running. Factory Default: OFF (Range:

Adjusts the boiler output down from
100% to 50%. Factory Default: 100%.
(Range: 100% – 50%)
Cascade Mode
Allows the user to select the cascade
mode. If one or more 1000 or 1700
units are cascaded in a common
vent manifold, select the number of
individual cascaded boilers in the
system on the cascade master (2
BOILERS if a single MOD CON 1700, 6
BOILERS if three MOD CON 1000s, etc.)
On cascade followers in a common
vent system, select COMMON FLUE
to establish a cascaded system WITH
common vent. Factory Default: 2
BOILERS on Cascade Master (bottom
boiler), COMMON FLUE on Cascade
Follower (top boiler). Range: ALL 926
/ 2 – 8 BOILERS [on cascade master
ONLY] / COMMON FLUE [on cascade
followers ONLY]). NOTE: All MOD
CON 1000 and 1700 boilers are to be
configured as COMMON VENT systems.
Cascade Rotation
Sets the amount of hours before the
first boiler in the cascade firing rotation
will be changed. NOTE: If this is set to 0,
the firing order of the boilers will not
rotate. Default: 48 hours (Range: 0 –
240 hours).

This parameter controls how 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
DHW MODULATE MODE
up from low fire when there is a
NORMAL MOD
29
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).
Function 30
Extra Boiler Mode
Allows for a non Westinghouse boiler
to be controlled when the cascade
