Condition / Response
The discharge pressure, as measured discharge
pressure sensor, has exceeded 630 PSIA.
This warning is generated to give additional
information that could be used to determine why all
compressors on the circuit shut down due to an
Unexpected Compressor Shutdown diagnostic or why
a Compressor Failed to Start diagnostic is generated.
Even if the pressure has dropped below 630 PSIA the
historic diagnostics will still indicate that a high
pressure was detected.
Space CO2 sensor has failed out of range.
DCV control will be inhibited.
The Space Humidity sensor has failed out of range.
No action is taken for this sensor failure only the
Outdoor Air Humidity Sensor Active has special
action.
The Space Humidity sensor value not available.
Dehumidification and humidification will be disabled.
This drives a 'fall back' response to Economizer
Enthalpy decision.
Space Pressure sensor has failed out of range.
Statitrac control will be terminated and the Relief Fan
Speed and Relief Damper command will fall back to
OA Damper Tracking.
The input to the Hex IO module has failed.
The unit will fall back to the "Space Temp Cooling
Setpoint Default" setting on the front panel.
The input to the Hex IO module has failed.
The unit will fall back to the "Space Temp Heating
Setpoint Default" setting on the front panel.
VVZT/CVZT: Unit Shutdown
VVDA/CVDA: Unit continues to operate and disables
the following functions:
• All Unoccupied modes (heat, cool, DH),
• Daytime Warmup,
• Morning Warmup
• Pre Cool
The Space Temperature sensor input is out of range.
Multi-zone: If Space Temperature Active is invalid, all
functions requiring space temperature will be
inhibited.
Single-zone: Unit operation will be inhibited.
The circuit X compressor Y cumulative value of starts
and or hours have been modified by a write override
from TU.
No unit response.
