SMART SYSTEM includes a built-in cascading sequencer for up to 8 KNIGHT XL units. This eliminates the initial cost and labor required with installation of a separate sequencer. And, because it’s engineered specifically for Lochinvar boilers, it removes any uncertainty about using a ”third-party” sequencer, to ensure precise, dependable cascading operation.
When utilizing the built-in cascading sequencer, KNIGHT XL boilers communicate through a simple 2-wire daisy chain connection. On demand, one boiler in the system functions as the leader, and modulates with demand to capacity. The additional load then ”cascades” to the second boiler, which fires and modulates to meet added demand via a patented process to match system load and reduce equipment short cycling.

When demand drops, the patented cascading process reverses, with the precision, control and performance you expect from Lochinvar.
SMART SYSTEM also controls Lead-Lag Rotation. Every 24 hours the lead boiler role is shifted to the next unit in the sequence. This rotation ensures long life by distributing ”lead-lag” runtimes equally over each unit in the system.
