When ever there is electricity failure to the unit and after resumption of the power, unit will start in the same mode as prior to the power failure. Memorized condition are on/off condition, operating mode (cooling/heating), set temperature and fan speed. The unit will memorize the above conditions and start with same memorized condition.

Wired Remote Control:

It can control all the functions of the unit. You can check/set temperature, set timer, holiday & also diagnose the error of the unit. It also has the option of weekly program.

Group Control:

It enables to control up to 16 units with the help of one wired remote controller. All the units will follow same setting of temperature & other sub functions.

Self Diagnosis Function:

This function provides diagnosis of the unit. An error code will be displayed on the LCD wired remote controller & diagnosis can be done as per the code indication. The same is also printed on key cover of the LCD wired remote controller.

Weekly Program:

Two Thermistor Control(Return Air Control): (Accessory)

There may be a significant difference between the return air temperature in the duct and the room temperature. Return air sensing tempeaturee is designed to control temperature more accurately by applying additional thermistor which senses the return air temperature inside the duct specially. After selecting the duct thermistor, which is connected to the main PCB, the room temperature measurement by LCD wired remote control thermistor is neglected. It helps to control the room temperature more accurately.(Thermistor is a field-installed accessory)

Fire Alarm Function:

By purchasing a fire alarm locally, installation of the fire alarm is possible. In case of any fire, alarm will sound and the unit will be completely stopped.
