2: Fan is turned on continually when the external heater is turned on,
3: Fan is turned off when the external heater is turned on with cooling only indoor unit
Cooling only indoor unit: To use this option, install the Mode Select switch(MCM-C200) on the outdoor unit and fix
it as cool mode.
- If Fan is set to off for cooling only indoor unit by setting the SEG9=3 or SEG15=3, you need to use an external
sensor or wired remote controller sensor to detect indoor temperature exactly.
(*5) When indoor unit is in cooling or Dry mode, The output signal is "ON"
(*6) For free cooling control, Economizer controller is required.
(*7) This function can be applied to 4 Way Cassette and Mini 4 Way Cassette only.
If the air conditioner operates the heating mode immediately after finishing the cooling mode, the condensate
water in the drain pan becomes water vapor by the heat of the indoor unit heat exchanger. Since the water vapor
might be condensed on the indoor unit, which may fall into a living space, use this function to get rid of the water
vapor out of the indoor unit by operating the fan (for maximum 20 minutes) even when the indoor unit is turned off
after cooling mode is turned to heating mode
