Wire the Burner
Install the burner and all wiring in accordance with the
National Electrical Code and all applicable local codes or
requirements.
Wire the burner in compliance with all instructions
provided by the appliance manufacturer. Verify operation
of all controls in accordance with the appliance
manufacturer’s guidelines.
See
Figure 11a
(7505P) or
11b
(RM7897A) for a typical
wiring diagram (Diagrams are for reference purposes only).
Trial For Ignition
: The oil solenoid valve is
energized. A
fl
ame should be established within the
factory set trial for ignition time (lockout time).
Lockout
: The control has shut down for one of the
following safety reasons:
The trial for ignition (lockout) time expired
without
fl
ame being established.
The cad cell detected
fl
ame at the end of the
Valve On Delay state.
To reset the control from lockout click the button
1-second.
NOTE:
A recurrence of the above failure modes
or a failed welded relay check could cause the
control to enter a
Hard Lockout
state that must
be reset only by a quali
fi
ed service technician.
To reset from Hard Lockout, hold the reset button
for 15 seconds until the yellow light turns on.
Ignition Carryover
: Once
fl
ame is established,
the igniter remains on for 10 additional seconds to
ensure
fl
ame stability.
Run
: With a
fl
ame established and the control
continuing to detect a
fl
ame, the burner will operate
in the RUN mode until the load demand is satis
fi
ed
or a limit opens.
If terminals RC1 and RC2 are jumpered, the
burner operates in the Low-High-Off Mode. The
burner starts at Low, goes to High after the
fl
ame
stabilization period. Flame is extinguished when
the load is satis
fi
ed or a limit opens, and the
burner is sent to Motor-Off Delay.
If a high/low control has been wired between
terminals RC1 and RC2 the burner starts at
Low and is released to go High after the
fl
ame
stabilization period. It can repeatedly cycle
between low and high as necessary to meet load
demand until the load is satis
fi
ed or a limit opens.
The burner is then sent to Motor-off Delay.
Recycle
: If the
fl
ame is lost while the burner is
fi
ring, the control shuts down the burner, enters a
60 second recycle delay, and repeats the ignition
sequence. The control will continue to Recycle
each time the
fl
ame is lost, until it reaches a pre-set
time allotment. The control will then go into Hard
Lockout instead of recycle. This feature prevents
excessive accumulation of oil in the appliance
fi
ring
chamber.
Motor-Off Delay
: The oil solenoid valve is turned
off and the control delays turning the motor off
for the set motor-off delay time before the control
returns to standby.
Pump Prime:
The igniter and motor are on with the
oil solenoid valve energized for 4 minutes. During
Pump Prime mode, the cad cell is disregarded,
allowing the technician to prime the pump without
having to jumper the cad cell.

Typical Burner Sequence of Operation -
GeniSys 7505
Refer to the appliance manufacturer’s wiring
diagram for actual speci
fi
cations. Note: GeniSys
7505 Control on CF2500A only.
Standby
: The burner is idle, waiting for a call for
heat.
Valve-On Delay
: The igniter and motor are on while
the control delays turning on the oil solenoid valve
for the programmed time.

Electrical Shock Hazard
Electrical shock can cause severe personal injury or death.
Disconnect electrical power before installing or
servicing the burner.
Provide ground wiring to the burner, metal control
enclosures and accessories. (This may also be
required to aid proper control system operation)
Perform all wiring in compliance with the National
Electric Code ANSI/NFPA 70 (Canada CSA C22.1).

Incorrect Wiring Will
Result in Improper Control
Operation
GeniSys 7505 Control wiring label colors may
not match the wire colors of the burner or other
manufacturers’ controls.
The GeniSys Control should be wired according to
the appliance manufacturer’s instructions.
y
y
Fire or Explosion Hazard
Can cause severe injury, death, or property damage.
The control can malfunction if it gets wet, leading to
accumulation of oil or explosive oil vapors.
Never install where water can
fl
ood, drip or
condense on the control.
Never use a control that has been wet - replace it.
