Overview of Primary Product

The DIP switches are located on the logic module, which is mounted in the second position from the

left on the motherboard next to the relay module.

To gain access to the DIP switches, the cover of the logic

module must be removed. To do this, remove the four screws

which hold the cover onto the motherboard. Then gently pull

the logic module towards you to disengage the logic module

from its mating connector. Located on the outside of the

cover is a label describing the function of the DIP switches.

For all dip switches, the ON position is toward the top of

the logic board.

WARNING: THE INAPPROPRIATE SELECTION OF DIPSWITCHES COULD RESULT

IN AN UNSAFE CONDITION HAZARDOUS TO LIFE AND PROPERTY. Changing the

dipswitches modifies the operation of the Multi-Burner Control System. Care should be

taken to insure the proper dipswitch settings. Setting the dipswitches for a particular appli-

cation should be made by a competent professional, such as a Boiler/Burner technician

licensed by a state or government agency, engineering personnel of the burner, boiler or fur-

nace manufacturer (OEM) or in the performance of duties based on the information from

the OEM.
