Functions

• Dividing area by zones (4zones) and control each zone by its own ther­mostat and corresponding dampermotor.

• In the cooling mode:
In case of Ceiling Concealed Duct, if the temperature of the zone is
lower than the set temperature in that condition the damper will be
closed & rpm of the fan motor is varied to adjust the reduced require­ment of air.

On the other hand:
If the temperature of the zone is higher than the set temperature in
thatc ondition the damper will be open so as to supply cold air to the
zone and vice versa in heating mode.

• In case all the dampers are closed in that condition indoor fan, outdoor
fan & compressor will be off.

These cords may only be used if their length does not exceed 2 m between the point
where the cord or cord guard enters the appliance and the entry to the plug.

b

Cords having the cross-sectional areas indicated in the parentheses may be used for
portable appliances if their length does not exceed 2 m.

NOTE: For supply cords supplied with multi-phase appliances, the nominal cross-sectional

area of the conductors is based on the maximum cross-sectional area of the conduc­tors per phase at the supply cord connection to the appliance terminals.
