outlet temperature and acts as temperature limiting governor. Setpoint limit is based on a

PID function that automatically limits firing rate to maintain outlet temperature within a 0

temperature.

an internal setpoint if its external control signal is lost, rather than shut off. This is a

selectable mode, enabling the control can to shut off the unit upon loss of external signal,

if so desired.
