Default Range
If a lockout condition occurs, and the combustion air fan was running, it will continue
running in the lockout phase (phase 00) for this period of time. This time replaces the
120s 0.2s-63min
postpurge time in the event of a lockout. If the combustion air fan was not running, the fan
will remain off for the rest of the lockout phase.
When the LMV5 gets a call for heat, this is the maximum time the LMV5 will hold in phase 21
waiting for a start release. If this time expires and the start release is not made, the LMV5
120s 0.2s-63min
will go into alarm.
