APPLICATION
The Honeywell YP7999A1000 ControLinks Fuel Air Ratio
Control Panel is a packaged, pre-wired panel that includes the
R7999A ControLinks controller for linkageless fuel/air ratio
control. The included S7999D color touchscreen interface
allows commissioning of the ControLinks system as well as
monitoring and control, all with user-friendly menus. On board
selector switches, buttons and alarm lights are included for
customer convenience. The ML7999A2001 universal direct
coupled actuators are purchased separately.
This document provides installation instructions and operation
information. Other applicable publications are:
100 – 120 Vac, 50/60 Hz, 3 Amps
For individual ratings, see component literature for details.

Approvals
Components are individually approved by the nationally rec-
ognized agencies. Please see component literature for
details. The panel has UL 508A flame control panel
approval. Panel is assembled and wired to the UL Standards.
INSTALLATION
When Installing This Product…
1. Read these instructions and the appropriate product lit-
erature carefully. Failure to follow them could damage
the product or cause a hazardous condition.
2. Refer to the installation manuals and wiring diagrams
provided with this panel for the embedded products.
3. Check the ratings given in the instructions and on the
product to make sure that the product is suitable for your
application.
4. Installer must be a trained, experienced combustion service technician.
5. Disconnect the power supply before beginning installation to prevent electrical shock and equipment damage.
More than one disconnect may be involved.
6. All wiring must comply with the National Electric Code
(NEC) and any applicable local electrical codes, ordinances and regulations.
7. After installation is complete, check out product operation as provided in the appropriate product installation
instructions.
Fire or Explosion Hazard. Can cause severe injury,
death or property damage.
To prevent possible hazardous burner operation, verify
safety requirements each time a controller is installed
on a burner.
WIRING
Electrical Connections
1. Refer to the appropriate product data sheet for details.
2. Wire size and length will vary, depending on the compo-
nent. Refer to the component literature for specific wire
lengths, sizes and type recommendations.
3. Wire according to specifications, following all local ordinances and requirements.
4. Field knockouts are required for the wiring. When drilling holes, take care to protect the electronics from metal
pieces and debris.
IMPORTANT
Run line voltage and low voltage wiring in separate
conduit to avoid signal interference.
Carefully check field wiring and terminal designations in this document and the associated wiring diagram. They are different from those of the individual
components.
Panel Inspection
After mounting and wiring, but before powering the panel,
inspect all internal panel wire connections. Each panel is fully
tested at the factory; however, wires may loosen during transit.
Verify that all internal wire connections are secure from the
Q7999 subbase to the components mounted on the door and
the S7999D touchscreen interface.
Final Wiring Check and Static
Checkout
All wiring shall be in accordance with the National Electric
Codes (NEC) and local electrical codes.
1. Check the power supply circuit. The voltage and frequency must match the specification listed.
2. Check wiring terminations and routing to ensure proper
connections.
3. Follow any system checkout recommendations for individual components as found in the component literature.
4. Restore power to the panel.
Electrical Shock Hazard. Can cause serious injury,
death or equipment damage.
Disconnect the power supply before beginning wiring
to prevent electrical shock, equipment and control
damage. More than one disconnect may be involved.
Ground Connection
Earth ground is required for proper operation of the
ControLinks system. The earth ground must be capable of
conducting enough current to blow the fuse or breaker in the
event of an internal short. Ensure the panel is bonded to a
substantial earth ground. Make sure that mechanically
tightened joints along the ground path are free of
nonconductive coatings and protected against corrosion on
mating surfaces.
66-2060—012
Test each limit and interlock to ensure system
operates correctly as defined in the 7800 Series
“Checkout and Test” document (Form #65-0229).
Explosion and Electrical Shock Hazard.
Can cause serious injury, death or equipment
damage.
1. Close all manual fuel shutoff valves before starting
these tests.
2. Use extreme care while testing the system. Line voltage
is present on most terminal connections when power is
on.
3. Replace all limits and interlocks that are not operating
properly. Do not bypass limit and interlocks.

TROUBLESHOOTING
System Diagnostics
The S7999D touchscreen interface indicates the current fault and keeps a fault history log. The R7999 ControLinks control and
the ML7999A Universal Parallel-Positioning Actuator also have LED fault blink codes. Refer to the appropriate product instruction
sheet for further troubleshooting information and diagnostic codes.
