12.2 RWF 40 Burner temperature controller
The RWF40 is used to control the boiler temperature.
It is configured to modulate the burner up and down when firing on gas
and provide high/low thermostat functions when firing on oil.
In modulating operation the RWF40 operates as a PID controller. In 2-
stage operation the RWF40 provides control based on the set switching
threshold. The setpoint of the RWF40 can be adjusted either on the
controller itself or externally.
