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
configurations 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.
