The second message indicates the system run time in
days – hours – minutes – seconds. Please note that
this is not accumulated run time but pertains only to
the current system cycle.
The third message indicates the system, and whether
the liquid line solenoid and hot gas solenoid are being
commanded on by the micro board. Please note that hot
gas in not available for system 2, so there is no mes-
sage pertaining to the hot gas solenoid when system 2
message is displayed.
The fourth message indicates what stage of condenser
fan operation is active. Unless a low ambient kit is added,
only stages 1 and 2 will be used to cycle the condenser
fans. However, stage 3 may be shown in this display
without a low ambient kit added, but it has no effect.
See the section on Condenser Fan Control in the Unit
