CONTROL SYSTEM
Revision 0
12B.4.3 I FEEL
• The switchover between RCT by the remote controller and RT detected by the control
board can be done by “I FEEL” function. After receiving the “I FEEL” command from the
remote controller, MCU decide the operation mode of the air-conditioner by RCT detected
by the remote controller.
• In I-Feel Mode, IF I-Feel data hasn’t been received from the R/C for more than 4 minutes,
the I-Feel Mode would be suspended and the Room Temperature is replaced by the RT
from the local sensor. As soon as new I-FEEL data is received from the R/C, the I-FEEL
Mode will be resumed.
12B.4.4 E.S.F and Ionizer
• E.S.F and Ionizer will turn on when receiving a signal from the R/C. and IFAN on.
12B.4.5 Fresh- Air Function
• Fresh-Air has two ways: continuous and Auto.
• If the Fresh-Air signal from R/C is continuous, Fresh-Air is on till the signal is changed.
• If the Fresh-Air signal from R/C is Auto, Fresh Air will turn on for 20 minutes and then stop
for 20 minutes, it continues doing cycle by cycle till the signal is changed.
12B.4.6 EEPROM
• The data stored in the EEPROM include:
• the setting parameters, such as: on/off status, temperature, fan speed, mode, louvers auto
or fix, E.S.F , Ionizer, Fresh air, Timer status, Filter hour
