Figure 13A - Display Meaning
Modulation Control
Modulation of the burner’s fi ring rate is accomplished 
by driving the damper motor in small increments to 
either increase or decrease rate in response to boiler 
demand.  A pressure transducer (for steam boilers) or 
temperature sensor (for water boilers) senses boiler 
demand and communicates it to the controller.   Display 
and programming functions for the Siemens RWF40 
controller are shown in Figure 13A with the controller in 
the basic display mode.
Figure 13B - Manual Mode
The damper motor can be manually operated for set-
up and service of the burner by placing the controller in 
the manual mode, as shown in Figure 13B.  Press and 
hold the EXIT button for 10 seconds to enter the manual 
mode.  The manual operation light will illuminate.
Putting in manual mode:
Press and hold exit button for 
10 seconds.
Manual operation light will 
illuminate.
Figure 13C - Manual Operation
The damper motor can be driven from low to high or high 
to low by pressing the up and down arrows as shown in 
Figure 13C.  Pressing EXIT for 10 seconds returns the 
controller to the automatic mode.
Operation in manual mode:
Once in Manual Mode, the 
damper motor can be driven 
from high to low using the 
up/down arrows.
To return to the automatic 
mode, press and hold exit 
button for ten seconds.
Figure 13D - Operation Set Point
The operating set point can be changed as shown in 
Figure 13D.  Pressing the PGM button accesses the 
User Level of the software, where this change is made.  
The up and down arrow buttons raise and lower the 
operating set point.  Pressing EXIT returns the control to 
the Basic Display level and saves your changes.
Programming functions within the software are used 
to match its settings to the connected hardware, and 
to adjust the control’s response to unusual job site 
requirements if necessary.  A manual for the controller 
is provided with the burner to allow programming at that 
level.
Setting operation set point:
From the original display, press 
program button once. (User 
level)
Set point 1 is displayed.
Use up/down arrows to change 
setting.
When fi nished, press exit.
