Chart 3 shows the step motor swinging angle of E series conditioners of 9000Btu and12000Btu. the
angle between fully open position and complete shutdown hereafter is called omnirange angle. The
omnirange angle of E mold is 150
° . In the operational process of repeating motor. the operational
angle is always memorized. repeating motor follows 4 phase 8 beating type of drive.
1. Reset action of first electrify. step motor opens an omnirange angle to its opening direction. then
opens an omnirange angle to its closing direction. If in the course encounters starting up.then starting
up action immediately. with swing speed 22
° / s.
2. When machine is on(with remote control or button pressing). the air blade makes a complete
shutdown. then swing an omnirange angle to its opening direction. then back to initial point. While
heating.it stays at point 5( chart 3
） .while refrigeration.then swing back to point 2 （ chart 3 ） .
3. The flap button on remote control can set the air blade to free swing or Manual swing.
4. For free swing. the swing scope of heating is 50
° .as (chart 3)3-5.for cooling. swing scope is 50 ° .
2-4 in chart.swing speed is 5.5 ° / s.
5. When the machine is turned on. while remote control set air blade non-swing. swing angle swings to
a proper position according to different mode and fix. e.g. :cooling mode is
（ chart 3 ） position 2. heating
mold is （ chart 3 ） position 5. If it's set as free swing. no matter the fan is open or not. air blade swings
within limitation. If the remote control set non-swing. Air blade will stop at the set position.
6. Turn off (by remote control or button pressing).when the inside fan motor stops working.air blade
will close by itself.
7. Press the emergency switch
to get into automatic mold.air blade works according to cooling mode.
If the system selects a certain mode.air blade runs according to the selected mode requirement.
