CCB - Three position Dipswitch (Flame Control Section) SW2:
This dipswitch is similar to the FCB dipswitches described below, but with only three switches being used: the number of blower
speeds (switch #3), Hi Gas option (switch #2) and a spare (switch #1). Only the blower speed and Hi Gas options are the required
selection, within the CCB . The FCB1 always has a blower, igniter, flame checking, and the address is always stage 1, see Figure 16.
Dipswitch Function: Dipswitch Position
Switch 1: Spare:
Switch 2: Hi Gas pressure switch: On = Yes Off = No
Switch 3: Number of Blower Speeds: On = 1 speed, Off = 2 speed
Example of Dipswitch configuration:
No High Gas, 1 blower speed.
CCB - Ten Position Dipswitch (Central Control Section) SW1:
Dipswitch configurations are
READ ONLY ON POWER UP. These switches are only to be set at the factory or by authorized trained
personnel! Once set the boiler will operate according to the chosen options. If a switch is changed, power must be cycled before the
change will take effect. The status of all dipswitches can be observed on the system status screen on the UIM.

Switch 1: Selection of the type of boiler application: On = GB/LB Off = GW/LW
Switch 2: Trials for ignition: On = 3 Off = 1
Switch 3: IRI Gas Valve Option: On = IRI Off = No IRI
Switch 4: Controlling Probe: On = Tank (Remote) Off = Inlet
Switch 5: Powered Venter: On = Yes Off = No
Switch 6: Low Water Cut Off: (LWCO) On = Yes Off = No
Switch 7: Low Gas Pressure On = Yes Off = No
Switch 8: Spare:
Switch 9 & 10. Number stages (FCB's): 9 10 #stages
Off Off = 1
Off On = 2
On Off = 3
On On = 4
NOTE: If the unit powers up with the number of stages selected by dip switches exceeding the number of FCBs, the CCB will detect
this condition and go into a hard lockout. After changing the dipswitches to the correct number of stages, the power must be
cycled on and off to accept the change.
Example of Dipswitch configuration:
GW model, 1 ignition trial, IRI, Tank Probe used, No Power Vent, No LWCO,
No Low Gas, 3 stages.
