Condition / Response
Circuit X Suction Pressure sensor has failed out of
range.
Circuit X operation is terminated.
The Suction Temperature sensor has failed out of
range for circuit X.
Circuit X operation is terminated.
The Suction Temperature 2 sensor has failed out of
range for circuit X.
Circuit X operation is terminated.
High superheat is detected and severe enough to
shut down the circuit.
Circuit X operation is inhibited.
This diagnostic is generated to notify system control
integrators that the unit is operating in Supply Fan
VFD Bypass mode.
Any time the Supply Fans are not being commanded
On in Bypass Mode and a Flow Proving condition from
the Discharge Air Pressure sensor exists for 40
continuous seconds.
Unit operation is inhibited.
Any time the Supply Fans are being commanded On
in Bypass Mode and a No-Flow Proving condition from
the Discharge Air Pressure sensor exists for 40
continuous seconds.
Unit operation is inhibited.
Any time Supply Fan X is being commanded On in
Bypass Mode and a No-Flow Proving indication from
the fans VFD exists for 40 continuous seconds.
Failure of fan X with other fan available:
Generate "Supply Fan X Proving Failure"
diagnostic and lockout all heating operation.
Failure of fan X with other fan not-available:
Generate "Supply Fan X Proving Failure" and inhibit
unit operation.
The fixed speed compressor Y proving input on circuit
X has opened while the compressor is operating.
Sources for this condition are High Pressure Cutout
switch opening, a fault from the compressor
protection module, contactor failure or wiring.
Circuit X operation is inhibited.
The unit is in active economizer cooling. The
economizer (OAD) command has been lower than the
economizer position by 10% for 5 continuous
minutes.
No unit response.
