MULTI AIR TEMP CTRL Warmest or Average
Warmest Air Warmest air = use the warmest air temp from bonded controls; Average air
= use the average air temp from bonded controls
MULTI EVAP COOL
Synchronized or
Independent
Synchronized
Synchronized = synchronize bonded controller in refrigeration mode;
Independent = bonded controllers control temperature independently in
refrigeration mode.
MULTI EVAP DEFROST Synchronized or
Independent
Synchronized Synchronized = synchronize bonded controller in defrost mode; Indepen-
dent = bonded controllers defrost independently
MULTI EVAP SENSOR Shared or Unshared
Shared
Shared = share sensor readings from bonded controllers; Unshared = use
local sensor readings only
