An Abundance of Comfortable Features for Stores and Offices

Comfort

Switchable fan speed

High setting provides maximum reach while low setting minimises drafts.

Programme 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.

Hot-Start

Uncomfortable cold air draft is not discharged when heating starts or when switching to heat after defrosting.

Automatic cool/heat change-over
(Heat pump only)

Detects any difference in the preset temperature and actual room temperature and automatically switches to cooling or heating accordingly.

Timer selector

Operation starts when the preset time for the ON timer is reached and stops when the preset time for the OFF timer is elapses.


Work & Servicing

Up to 30 meters pre-charged

If refrigerant piping length does not exceed 30 m, there is no need for on-site gas charging.

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 keep 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 ccompressor can still be operated.

Self-diagnosis function

The operating parameters of indoor and outdoor units, and sensor 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.


Control Features

Auto-restart

If there is a power outage while the equipment is running, operation will restart in the same mode as when the power is cut once electricity is restored.

Control by 2 remote controllers

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 is not possible using 2 remote controllers.

 

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 the 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.

Interlock control with HRV

Enables interlock control with external equipment such as heat reclaim ventilation (HRV).


Others

Twin/Triple/Double-twin Multi application

Simultaneously operates 2 to 4 indoor units with a single outdoor unit.

PE fins

The outdoor unit's heat exchanger fin has been specially pretreated with an acrylic PE coating to improve their resistance to salt corrosion and atmospheric pollution.

Adjustable external static pressure
