MENU
ITEM
PURPOSE
Overview
• There are three inputs/outputs available on
each boiler. This menu allows assignment
of which inputs/outputs operate which
priority/system.
INPUT 1
INPUT 2
INPUT 3
• See “EVG control Priorities & Input/
Outputs” on page 4 for an explanation of
priorities, inputs and outputs.
• Priority settings are adjustable. See page 52
through page 55 for priority options.
• The Assign Inputs menu is for designating
priorities to the correct inputs according to
the system installed.
• Multiple inputs can use the same priority.
• The Source line designates Input 1 as either
thermostat controlled or 0–10V controlled
for MODULATION. (On Master/Shadow
systems, this line is not present and Input
1 is predetermined as a thermostat-con-
trolled input.)
• When choosing 0–10V as the Source, a
NOTICE screen will pop up explaining
the use of the 0–10V input. Press SAVE to
use this option, or press cancel to return
the input to TT1.
AUX PUMP/
OUTPUT
• The AUX PUMP/OUTPUT function en-
ables an output to turn on in a variety of
selectable conditions.
• See page 57 for explanations and recom-
mended applications.
• In network boiler applications, outputs
assigned AUX PUMP/OUTPUT are con-
trolled by the master boiler, based on the
input/output and blower behaviors of all
boilers on the network.
