It is operating individually or totally by central control function.
Group Control(Optional Wiring)
•
Each controller can control 16 units and 8 controllers can connect.
•
It operates maximum 16 units by only one wired remote controller and each unit starts random to prevent overcurrent.
• Room temperature sensor. (Thermistor)
•
Maintains the room temperature in accordance with the Setting Temp.
• Indoor fan is delayed for 5 seconds at the starting.
• Restarting is inhibited for approx. 3 minutes.
• High, Med, Low
• Intermittent operation of fan at low speed.
• Although the air-conditioner is turned off by a power failure, it is restarted automatically previous operation mode after power supply.
