Figure 13C - Manual Operation

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.

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.

Modulation of the burner’s firing 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

Putting in manual mode:

○Press and hold exit button for 10 seconds.

○Manual operation light will illuminate.

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.

Figure 13D - Operation Set Point

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 finished, press exit.

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.
