8.G.17 Lead Lag Follower Conguration
The Conguration Menu
At the top select ‘System Identication & Access’
Note: The system sensor and outdoor sensor will
need to be wired to the Master boiler only.
The input from these sensors is used by the Master
control to control the modulation rate of all the
operating boilers it is connected to. See the manual
for sensor and cascade wiring.
When a boiler is operating as part of a Lead Lag
system, it does not use the normal “CH set point” –
it uses the “Lead Lag CH set point” on the Master
control.
It is STRONGLY recommended to start each boiler
to complete combustion set up and perform all safety
checks before setting up Lead Lag cascade. See
‘Combustion Setup’ in this manual.
