7.3.7 Lockouts
If a lockout occurs to a boiler in a Cascade System, it will be removed from
Cascade System operation. The remainder of the Cascade System contin-
ues to operate and the next available boiler will fire if necessary. The
Lockout Screen will be displayed on the locked out boiler as well as the
Master boiler. The Master boiler Lockout Screen will also indicate which
boiler in the Cascade System is locked out.
