Event Action
Outdoor air differential pressure sensor value not in valid range. Might be tubing problem or high return duct resistance.
Service event logged
During free cooling damper is not modulating.
Economizer should be installed and blower should be ECM type.
Check outdoor air damper differential pressure sensor and wiring.
May be due to the damper motor being unplugged or disconnected.
my be due to damper motor being blocked open and not closing.
configuration id 1, position 2 is set to u. select applicable option using setup/install wizard.
This alarm will occur when the combustion air pressure switch (S18) is detected as closed immediately after the furnace
demand relay is energized and before the combustion air blower is energized. Gas valve 1.
This alarm will occur when the combustion air pressure switch (S45) is detected as closed immediately after the furnace
demand relay is energized and before the combustion air blower is energized. Gas valve 2.
System locked out due to S45 switch closed and a specific number occurrences detected based on Parameter 72 (MAX
CAI NO PRF OCC) setting during a single cycle.
Configuration ID 1, position 3 is set as U (unconfigured).
Configuration ID 1, position 4 is set correctly. if position 3 is configured then position 4 must be also.
If Configuration ID 1, position 6 - blower VFD bypass is set to A or M, then Configuration ID 2, position 1 must be set to C
or D.
Verify that Configuration ID 2, position 1 is set correctly.
Room bypass damper operation is only compatible with cab blowers. prodigy will only allow zone bypass unit operation if
configuration ID1 is set to installed for units with B or T type blowers. alarm will automatically clear when configuration
conflict is corrected.
Alarm will occur if load shedding input is shared with other optional devices or inputs, for example - global, blower
overload, drain pan overflow, etc.
This alarm occurs when a SBUS master device sends a M2 style command to the M3 unit controller. The alarm is
immediately cleared and a history of the event is stored.
