II - 36(3) Checking the indoor units and remote controller● Stop the outdoor unit test run and remove the forced thermostat OFF setting on the indoor units. (turn the Stopswitch (STOP SW) to “NORMAL”)● With each remote controller individually, check that thecombination of indoor unit and remote controller unitnumber display label agree.B type remote controllerc START/STOP checksn Press the remote controller button, to checkthe remote controller operation display.• During AUTO : “ ” is displayed• During DRY : “ ” is displayed• During HEAT : “ ” is displayed• During COOL : “ ” is displayed• During air FAN : “ ” is displayedNote 1: DRY cannot be used with an outdoor air process-ing unit with direct-expansion coil.Note 2: AUTO cannot be used with Multi System.o At the same time, while the fan of the indoor unit isrotating, check the FAN.• After starting operation in COOL and FAN modes,use the remote controller to operate the fan at the setair velocity.• In DRY mode, when the room temperature is higher than the temperature set with the remote controller, the fanoperates at the set air velocity, but the air velocity becomes “weak” when the room temperature approaches theset temperature.• In order to prevent blowing of cold air in heating mode, the fan may be either stopped or the air velocity maybe at a very low velocity for several minutes after operation starts, but the fan will operate at the air velocity setwith the remote controller afterwards.d Checking the operation modeCheck that the mode changes by pressing the remote controller button.● While operation mode is displayed, press the button, check that the mode changes.CAUTIONWhen operating with several remote control-lers, the message “Operation change beingcontrolled” is displayed, indicating that cooling/heating operation mode cannot be switched.(priority for the remote controller first pressed)Model Selectable modesOutdoor air processing unit withdirect-expansion coil AUTO, COOL, HEAT, and FANWater heat exchanger unit COOL (refrigeration) and HEAT (heat ap-plication)Other AUTO, COOL, DRY, HEAT, and FANe Checking air velocity changing(This is not available for the outdoor air processing unit with direct-expansion coil and water heat exchanger unit.)Press the remote controller button several times to check that the air velocity changes.● The air velocity can be adjusted to 4 settings: extreme, strong, weak, and automatic.● The outdoor air processing unit with direct-expansion coil is fixed to “extreme”CZ-RTC2 (Some items are not displayeddepending on the model)
