can be performed via the control thermostat or pressurestat depending on the
parameter settings in the PME7, otherwise a non-volatile lockout will be initiated. With
restarts from the operating position (loss of flame), the flame must have been
established on completion of the safety time, or else a non-volatile lockout will be
initiated.

safety time (TSA)
If there is no establishment of flame at the end of the safety time, a non-volatile lockout
will be initiated.
