The fourth message indicates what stage of condenser
fan operation is active. For YCAL0014 to YCAL0080 un-
less a low ambient kit is added, only stages 1 and 3 will
be used to cycle the condenser fans. However, stage
2 may be shown in this display without a low ambient
kit added, but it has no effect. YCAL0090 - YCAL0124
have 3 or 4 fan stages as standard.
See the section on Condenser Fan Control in the UNIT
OPERATION section for more information.

grammed under the OPTIONS Key. Combined com-
