FULTON Vantage VTG Series Installation And Operation Manual page 112

Typically used for condensing hydronic boiler applications, the ModSync will keep the boilers at lower firing rates
until all available boilers are on. Once all available boilers are running the ModSync will allow the boilers to
modulate up to higher firing rates.
Typically used for non-condensing/process applications, the ModSync will allow the lead boiler to go to a high
firing rate before bringing on a lag boiler. The lead boilers firing rate will continue to increase independently of the
other boilers as the other boilers firing rates increase as well.
