Lead/Lag Status
(T) Designates a temporary
position where the boiler will
take a normal place in the Lead/
Lag sequence after the next call
for heat.
*Boilers must be connected and
configured for the Lead/Lag
feature in order to be assigned a
Lead/Lag position.
*If communication is lost be-
tween boilers in a Lead/Lag setup
they will revert back to individu-
al/local control.
CAT5e Ethernet Cable from pass-
through port on back of the electri-
cal panel
Field Wired between boilers for a 2
boiler setup -or- if 3 or more boil-
ers then use the factory supplied
