U813 Select Condenser #— # represents the alternate condenser connected. Toggles between 

Condenser 1 and 2. When Select Condenser 2 is shown, the parameters U814 through U820 apply to 

Condenser 1. When Select Condenser 1 is shown, parameters U814 through U820 apply to 

Condenser 2.
U814 Fan Reversal Every x Days— Sets the numbers of days between fan reversals; adjustable 

from 1-100 days. The default value is 0 days = OFF. Fan reversal can be performed only with both 

compressors off. Fan reversal interval should be performed during standby periods. If the compressor 

is operating, the control will skip the scheduled reversal and retry the next interval day. If the 

scheduled fan reversal is missed, the control will look for the next available time to do a fan reversal 

where the compressor’s calls are met and initiate the reversal. If one or both of the compressor(s) is 

operating and/or the fan is in low noise operation, the request to reverse the fans will be ignored.
U815 Reverse Fan At:—Sets the time the fan reversal will be performed. The fan reversal time is 

set using a 24-hour clock.
U816 Reversal Duration—Sets how long the fan(s) will be operated in reverse; adjustable from 

0-999 seconds. The default is 60 seconds.
U817 Reverse Fans Now—Performs a rotation when set to YES. When set to YES, the parameter 

will automatically change to NO when the timer, U816, elapses. If one or both of the compressor(s) is 

operating and/or the fan is in a low noise operation, the request to reverse the fans will be ignored.
U818 Max Speed at OpMode 0 (LN)—Linked to U807 0=LN column and defines the maximum 

speed during Low Noise operation.
U819 Max Speed at OpMode 100 (HE)—Linked to U807 100=HE column and defines the 

maximum speed during normal or High Efficiency operation.
U820 Current Max Speed—Parameter show the status of the actual maximum fan speed.
