Safety
Attention should be paid to the following statements:
NOTE—Notes are intended to clarify the unit installation, operation
and maintenance.
CAUTION—Caution statements are given to prevent
actions that may result in equipment damage, property
damage, or personal injury.
WARNING—Warning statements are given to prevent
actions that could result in equipment damage, property
damage, personal injury or death.
DANGER—Danger statements are given to prevent
actions that will result in equipment damage, property
damage, severe personal injury or death.
ELECTRIC SHOCK, FIRE, OR
EXPLOSION HAZARD
Failure to follow safety warnings exactly
could result in dangerous operation, serious
injury, death, or property damage.
Improper servicing of HVAC equipment could
result in dangerous operation, serious injury,
death, or property damage.
• Before servicing, disconnect all electrical
power to the equipment. More than one
disconnect may be provided.
• When servicing controls, label all wires
prior to disconnecting. Reconnect wires
correctly.
• Verify proper operation after servicing.
Secure all doors with key-lock or nut and
bolt.
Electric shock hazard. Before servicing,
disconnect all electrical power to the
equipment, including remote disconnects,
to avoid shock hazard or injury from rotating
parts. Follow proper Lockout-Tagout
procedures.
WARNING
GROUNDING REQUIRED
All eld installed wiring must be completed
by qualied personnel. Field installed wiring
must comply with NEC/CEC, local and state
electrical code requirements. Failure to
follow code requirements could result in
serious injury or death. Provide proper unit
ground in accordance with these code
requirements.
WARNING
During installation, testing, servicing and
troubleshooting of the equipment it may
be necessary to work with live electrical
components. Only a qualified licensed
electrician or individual properly trained in
handling live electrical components shall
perform these tasks.
Standard NFPA-70E, an OSHA regulation
requiring an Arc Flash Boundary to be eld
established and marked for identication
of where appropriate Personal Protective
Equipment (PPE) be worn, should be followed.

Applications
The AAON®Pioneer Gold 1.10 & 2.05 Controller with Touch
Screen interface, BACnet®MS/TP, BACnet®IP (ASM02323 board
only), and ModBus RTU communication protocols is designed for
AAON®horizontal and vertical water-source heat pump units—WH
& WV series. All of the energy saving features and options available
on AAON®WH and WV Series water-source heat pumps can be
controlled with the Pioneer Gold Controller.
The Water-Source Heat Pump (WSHP) Pioneer Gold Controller
contains all the functionality required to operate basic and advanced
congurations of AAON®WH and WV Series WSHP units. The
controller can operate with a standard heat pump room thermostat
(by others) or can operate as a stand-alone system with the Pioneer
Gold Touchscreen Space & Humidity Sensor or Simple Space
Temperature Sensor.
The controller also contains a terminal block for communication
to the Pioneer Gold Electric Heat Board for additional heat stages.
NOTE: If the application currently uses an obsolete mercury
bulb type thermostat, it must be upgraded to an elec-
tronic thermostat. The unit will not function properly
when controlled via a mercury bulb thermostat.
The controller has outputs to control a supply fan, compressor, and
reversing valve. It also provides I/O for additional functionality.
The Pioneer Gold is used for Constant Volume applications.

General
Correct wiring of the Pioneer Gold Controller and its Electric Heat
Board, if applicable, is the most important factor in the overall
success of the controller installation process. In general, most
Pioneer Gold Controllers are factory installed and wired at the
AAON®factory. Some of the following information may not apply
to your installation if it was pre-wired at the factory. However, if
troubleshooting of the controller is required, it is a good idea to be
familiar with the system wiring.
The Pioneer Gold Controller dimensions are 8” x 5.5”. The Electric
Heat Board dimensions are 3.5” x 3.5”.
Electrical & Environmental
Requirements
The Pioneer Gold Controller and Electric Heat Board must be
connected to a 24 VAC power source of the proper size for the
calculated VA load requirements. All transformer sizing should be
based on the VA rating listed in Table 3.
