99 ALARM OUTDOOR ECON SENSOR A24 Check sensor and wiring.
100 ALARM AIR VOL CONTROL SETUP ERROR Check for proper installation of GP board and settings.
101 ALARM MGV CONTROL SETUP ERROR Check for proper installation of GP board and settings.
102 ALARM GP CONTROL SETUP ERROR Check for proper installation of GP board and settings.
103 ALARM ADVANCED CONTROL SETUP ERROR Check M3 unit controller Configuration ID 1 settings.
104 - 105 RESERVED
106 ALARM BUILDING PRESS SENSOR A34 Check sensor and wiring.
107 ALARM DUCT SUPPLY PRESS SENSOR A30
Check sensor and wiring.
The unit controller will set Supply Air Static Pressure Sensor (A30) error status if:
 Input signal is above 4.9" wc for more than 30 seconds.
 OR
 Input signal is below 0.1"wc 20 seconds after the blower has started with setting at or above Blower Output  Static Duct
Alarm Check.
The m3 unit controller will clear the Supply Air Static Pressure Sensor (A30) error status and alarm after the expiration of
Error Time OFF delay.
108 ALARM DUCT SUPPLY HIGH PRESS SENSOR A30
Check sensor and wiring.
The unit controller will shutdown operation for Error OFF time (Parameter 110) if supply supply air static pressure exceeds
Supply static shutdown setpoint for 20 seconds (default) Parameter 42.
The unit controller will clear High Supply Static (Duct) Pressure after Error OFF Time has expired and static duct pressure
is below Supply Static Set Point Shutdown.
109 ALARM STRIKE 3 DUCT SUPPLY PRESS SENSOR A30
Check sensor and wiring.
Prodigy controller shall "lockout" a unit operation after the Max Static Duct Pressure Occurrences have occurred of Sup
ply Static Pressure Sensor Error (alarm 107) and/or High Supply Static (Duct) Pressure (alarm 108).
User shall be able to clear Supply Static Pressure lockout & alarm via User Interface. Supply Static Pressure lockout &
alarm shall be cleared after the Prodigy controller reset.
The number of strikes is three by default. this can be changed using parameter 43. Optional occurrence setting is 1 to 7.
110 ALARM WAITING ON NETWORK DATA Check network or comfort sensor and wiring.
111 - 120 RESERVED
121 ALARM LINE FREQ DOES NOT MATCH UNIT CONFIG
Powersource line frequency is determined by the entered model number. This alarm is enabled by the PhaseVoltage
Detection feature. M3 unit controller does not have an automatic clearing method, unit power cycle or reset will be required
to re-evaluate the phase sequence again.
122 ALARM 24VAC PRIMARY VOLTAGE LOW
Low output voltage on T1 transformer. alarm set when 24VAC voltage low if calculated RMS voltage is below low voltage
alarm threshold for more than two seconds. System will stop unit operations (cooling, heating and ventilation). Low voltage
threshold is 18VAC.
The M3 unit controller will clear alarm 24VAC Voltage Low if calculated RMS voltage is above Low Voltage Alarm
Threshold + 1 VAC for more than two seconds. After the low 24VAC alarm has been cleared, the M3 unit controller will
ignore all service demands until the Error Time Off Delay has expired.
