Unit operations must be controlled with
thermostat and unit controller, never at the
main power supply, except for emergency or
complete shutdown of the unit.
AAON WSHP Pioneer Silver Controller
Part Number: V67470
Description
The Water-Source Heat Pump Pioneer
Silver Controller contains all the
functionality required to operate the basic
configuration of AAON WH Series units.
The controller requires commands from a
standard heat pump room thermostat and has
outputs to control a supply fan, compressor,
and reversing valve. The control also
contains a port for communication to the
Water-Source Heat Pump Pioneer Silver
Expansion Board for additional
functionality.
NOTE: If the application currently uses an
obsolete mercury bulb type thermostat, it
must be upgraded to an electronic
thermostat. The unit will not function
properly when controlled via a mercury bulb
thermostat.
