E.S.P.(External Static Pressure) Setting
(1) Open the rear cover of the wired remote-controller to set the mode.
(2) Select one of three selectable modes as follows.
(2) Select one of three selectable modes as follows.
■
Without Zone System
1. Position V-H, F-H:
• This position sets the maximum E.S.P as a default set.
2. Position V-L:
• This position sets the minimum E.S.P as a default set.
■
With Zone System
1. Position V-H:
• Maximum E.S.P setting & Fan speed is varied according to the state of dampers by micom.
2. Position F-H:
• Maximum E.S.P setting & Fan speed doesn't vary according to the opening & Closing of dampers.
3. Position V-L:
• Minimum E.S.P setting & Fan speed is varied according to the state of dampers by micom.
*Maximum: 18/24K-8mmAq
36K-10mmAq
Minimum: All-0mmAq
(3) Move the slide switch to set position.
(4) Close the rear cover and check if it works normally.

Procedure of RPM change:
Ex) External Static pressure is 6mmAq for Model Name "LB-G3680HL"
• To protect the unit, compressor is designed to be off during E.S.P. setting.
Push the "On/Off" button.
The unit will start.
The unit will start.
Push the "Timer" and "Wind" button simultaneously for more then 3 seconds.
Push the "Up" of "Down" button for E.S.P adjustment.
And, adjust the number which you want.(In this example, the number is "220". Refer to the table
1 on the next page.)
And, adjust the number which you want.(In this example, the number is "220". Refer to the table
1 on the next page.)
Shift the fan speed mode by pressing the fan speed button.
And then, Adjust numbers of next steps by repeating the stage 3.
(In this example, the numbers are "235" and "243" respectly)
And then, Adjust numbers of next steps by repeating the stage 3.
(In this example, the numbers are "235" and "243" respectly)
Push the "Timer" and "Wind" button simultaneously for more than 3 seconds.
Then, Wind Data is memorized by the EEPROM of the main PCB.
Then, Wind Data is memorized by the EEPROM of the main PCB.
Note: The range of selection is from 1~254. Since, the display is two Digit only.
If the range selection is above 100 then the third digit will appear in the screen as shown.
