Introduction

Quiet, décor-blending form and easy installation in new or old buildings.

Models :
FFQ25B, FFQ35B, FFQ50B, FFQ60B,
(Available in both cooling only and heat pump models.)

Comfort	Cooling Only	Heat Pump
Auto Swing Delivers comfortable air-conditioning to all areas, near to and far from the air-conditioner.
Swing pattern selection You can freely set 3 air flow positions by remote controller. 1. Air flow range in standard position 2. Air flow range in draft prevention position 3. Air flow range in ceiling soiling prevention position
Draft Prevention Function To prevent cold air drafts, automatically adjusts air flow to horizontal vector when heating initially starts or when the thermostat turns off.
Switchable fan speed High setting provides maximum reach while low setting minimizes drafts
Program ‘Dry’ Dehumidification is computer controlled to prevent abrupt and uncomfortable changes in air temperature. Useful for reducing discomforting humidity without uncomfortable cooling of the room.
High ceiling application Delivers air-conditioning comfort all the way down to the floor in air-conditioning zones with high ceilings.
Two selectable thermo-sensors Thermo-sensors are included in the indoor unit and optional wired remote controller. Termperature detection closer to target area is possible to further increase the fomfort level. *Use the thermo-sensor in the indoor unit when controlling air conditioning from another room.
Hot Start Uncomfortable cold air draft is avoided when heating operation starts or when switching to transparent, the drain heat after defrosting.
Year-round cooling applicable Efficient cooling even in winter when indoor temperatures are higher than those outside, such as in undergroung public spaces or office with many computers. * Heat pump/RY71 - 140LU: possible up to -50C *Cooling only/RY71 - 140LU: possible up to -150C (An option is required.)
Time Selector Operation starts when the preset time of the ON timer elapses and stops when the preset time of the OFF timer elapses.

Mould prevention	Cooling Only	Heat Pump
Mold resistant treatment for filter Sanitary filter has mold-resistant treatment.

Control Features	Cooling Only	Heat Pump
Auto-restart If there is a power outage while the equipment is operating, operations will restart in the same mode as before the power cut when electricity is restored.
Auto Cooling/heating Change-over
Interlock control Enables interlocking control with external equipment such as heat reclaim ventilation (HRV).
Control by 2 remote Using 2 remote controllers you can operate the equipment locally or from a remote location. Note: When a wireless remote controller is used, remote control by two remote controllers is not possible.
Control by 1 remote controller You can turn up to 16 indoor units on/off with a single remote controller. (When using connected indoor units, the settings must all be the same and on/off will be simultaneous.)
External command control Operation and surveillance is carried out using the contact signal from the operation control box in teh building surveillance (security) room.
Central remote control Optional central remote controller enables centralized control of up to 1024 indoor units (64 groups) from up to 1 Kilometer away.

Work & Servicing	Cooling Only	Heat Pump
Drain water lift-up mechanism
Pre-charged for up to 30 m If refrigerant piping length does not exceed 30 m, there is no need for on-site gas charging.
Ceiling soiling prevention
Filter sign The filter sign warns you when it is time to clearn the filter. * When using a wired remote controller the sign is displayed in the LCD. When using a wireless remote controller the filter sign lamp illuminates on the singnal receiver unhit.
Low gas pressure detection Insufficient gas charging is normally hard to detect. During post-installation trials and regular inspection procedures, the refrigerant level is monitored by computer to ensure proper gas pressure. Reliability is assured and maintenance and inspection can be carried out more quickly.
Emergency operation If there is a malfunction elsewhere in the system, the fan or compressor can still be operated.
Self-diagnosis function The operating parameters of indoor and outdoor units, and sensosr data at critical locations throughout the system, are constantly monitored using a microcomputer. To facilitate quick response in the event of a malfunction, a message appears on the LCD of the remote controller and an LED on the unit illuminates.

PE fin To achieve increased durability by improved resistance to salt corrosion and atmospheric pollution, coated PE fins (with special acryl pretreatment) are used for the heatt exchanger of the outdoor unit.

Applicable when wired remote controller is used
