Trouble shooting
(
*1) Minimal Fan operation during Thermo Off
‑ Fan will run for 20 seconds every 5 minutes during heating Thermo off
‑ Fan will stop or run at ultra‑low speed depending on settings during cooling Thermo off
(*2) 1: Fan will always be On if hot water heater is On
3: Fan will be Off if hot water heater in cooling‑only indoor unit is On
[In order to use the applicable option function, a cooling and heating converter (ACM‑C200) must be installed in the outdoor unit and
fixed to cooling mode]
(*3) If 2, 3 is selected to use as external heater On/Off signal, the external contact point control Monitoring signal will not be
outputted.
2: Fan will always be On when external heater is On
3: Fan will be Off when external heater is On in the cooling‑only fan coil unit
[In order to use the applicable option function, a cooling and heating converter (ACM‑C200) must be installed in the outdoor unit and
fixed to cooling mode]
※ If set as SEG9=3 or SEG15=3 to set Fan Off regarding the cooling‑only fan coil unit, the external sensor or cable remote control
sensor must be used to accurately detect indoor temperature.
(*4) Output will be generated when running cooling or dehumidifying mode
(*5) An Economizer control is required to set outside air introduction cooling
(*6) Initial setting value
‑ 4‑Way cassette, compact 4‑Way cassette: 5 ℃
‑ Other fan coil units: 2 ℃
(*7) This function only applies to the 4‑Way cassette and compact 4‑Way cassette. If the outdoor unit switches to heating operation
right after cooling is finished, the condensate water remaining in the Drain Pan will evaporate due to the heat of the fan coil unit heat
exchanger. This may then condense on the surface of the product and drip into the living space. If using the applicable option, after
the outdoor unit switches from cooling to heating, run the Fan (for maximum 20 minutes) even if the relevant fan coil unit is turned
off so that the steam will be discharged outside the unit.
