Operational Modes
All modes operate the overhead fan and/or a heating or cooling cycle based on the current
heating or cooling set-point, relative to the inside temperature.
Fans and Fan Only Mode
This mode lets the fan to operate based on the chosen (8) Fan Speed.
This will circulate the air without operating any heating or cooling cycles.
Cool Only Mode
This mode only runs a cool cycle to maintain the cooling set-point in the
space. Set the (7) Operational Mode button to Cool Only and the desired (8) Fan
Speed, where behavior will then be based on Table 5. A time delay of
approximately three minutes occurs before a cooling cycle begins. This allows
pressure to equalize in the system to prevent compressor damage.
