Lead / Lag Configuration 3
FIGURE 30 – LEAD / LAG SCREENS PAGE 3
Modulation at Next Stage CV:
Defines the firing rate of the boiler before
each consecutive stage. For example if the Modulation at Next Stage CV is
20% when the lead boiler is running then the ModSync® will allow it to run
up to a 20% firing rate before it brings on the lag 1 boiler.
1st Lag Stage Start CV:
Defines the CV (as generated by the PID) that
enables the lag 1 boiler. This will also determine the point at which the
lead boiler will be at the Modulation at Next Stage firing rate %.
1st Lag Stage Stop CV:
Defines the CV (as generated by the PID) that
disables the lag 1 boiler.
Additional Lag Enabled CV:
Additional CV percentage that is added to
the 1st lag stage start CV and 1st lag stage stop CV for each additional
boiler.
