INPUTS AND OUTPUTS
Controller Input and Output Descriptions
Pioneer Gold Controller I/Os
SPT - Suction Pressure Transducer
(By Others)
The Suction Pressure Transducer is an optional transducer used
to monitor the Suction Pressure (0-500 psi).
DPT - Discharge Pressure Transducer
(By Others)
The Discharge Pressure Transducer is an optional transducer
used to monitor Discharge Pressure (0-667 psi).
SAT - Supply Air Temperature Sensor
The Supply Air Temperature Sensor is a 10k ohm Type III
thermistor sensor used to measure the Supply (Discharge) Air
Temperature. This sensor comes shipped loose in the WSHP
when the Pioneer Gold Controller is ordered.
CO
2
- Space CO
2
Sensor
2
Sensor. Sensor must
output 0-10V and have a range of 0-2000 ppm.
SPAT - Space Temperature Sensor
The Space Temperature Sensor is a 10k ohm Type III thermistor
sensor used to measure the Space Temperature. If also using
the Pioneer Gold Digital Touchscreen Space Temperature and
Humidity Sensor, the controller will default to the digital sensor.
DMPR OVR - CO
2
Damper Override
This output is used to signal an Outdoor Air Damper if the CO
2
level goes above the setpoint. Output is 0 volts when below the
setpoint and 10 volts when above the setpoint.
COF 2 - Condensate Overow 2
Input. An alarm will be generated any time the resistance between
this input and ground is less than 100K ohm. This Alarm disables
the Compressor outputs as well as the main fan. This can either be
a 24 VAC wet input or a dry contact between COM and the input.
AUX - Auxiliary Fault Switch
When this input is energized, the Auxiliary Fault Alarm will
occur. Once the compressor completes its Minimum Run Time,
it will be de-energized and the fan will continue to run. This can
either be a 24 VAC wet input or a dry contact between COM
and the input.
ESD - Emergency Shutdown Input
The Emergency Shutdown is a 24 VAC wet input. If 24 VAC is
removed from this input, all outputs are de-energized.
WARNING: The Emergency Shutdown input is not to be
used for Life Safety applications.
NSB OVR - Night Setback Override
If the “Night Setback Enable” (see next Input) is energized
and this input is momentarily energized, the unit will go into
Occupied Mode for two hours and look at normal thermostat
inputs and then return back to Unoccupied Mode. If the “Night
Setback Enable” is removed, the two-hour timer is reset. This is
a 24 VAC wet input.
NSB - Night Setback Enable
If the unit is being controlled by a thermostat, this input can
be used to force the unit into Unoccupied Mode. While in the
Unoccupied Mode, the unit will look at the “Night Setback”
input for a Heating call. All other thermostat inputs are ignored.
This is a 24 VAC wet input.
NSB TH - Night Setback Thermostat
If the Night Setback Enable is energized, this input is used to put
the unit into Heat mode while Occupied. Typically this signal
This is a 24 VAC wet input.
R - 24 VAC - Thermostat
This is the 24 VAC output to thermostat “R” connection.
G - Fan Call - Thermostat
This is the Fan call from a thermostat. This is a 24 VAC wet input
Y1 - Compressor Stage 1 Call - Thermostat
This is the Compressor Stage 1 Call from a thermostat. This is
a 24 VAC wet input.
Y2 - Compressor Stage 2 Call - Thermostat
This is the Compressor Stage 2 Call from a thermostat. This is
a 24 VAC wet input.
COM - Common or Ground - Thermostat
This is the common or ground connection for the thermostat.
