11 Manual Unit Control and LED indicators
The push button switch and the LED indicators on display panel let the user to control the unit
operation without a R/C (Remote Controller). Their operations are provided below.
Push Button Switch :
Use to cycle the operation mode of the A/C unit among COOL, HEAT and
OFF modes, without using the R/C.
OPERATION
BUTTON
Every time this switch is pressed, the next operation mode is selected,
in order:
- Off => Cool mode => Heat mode => Off => … (for heat pump model)
- Off => Cool mode => Off => … (for cooling only model)
- The A/C will start in Auto IFAN speed and Flap mode as the last setting.
The temperature setting is 22°C for cooling and 28°C for heating mode.
WARNING:
the OFF position does not disconnect the power. Use the main power switch to turn off power completely.

OPERATION
LAMP
1. Lights up during Timer and sleep operation.
2. Blinks continuously in case of any wiring trouble.
1. Lights up when the Air conditioner is connected to power and
ready to receive the Remote Control command.
2. Blinks continuously in case of any thermistor failure.
1. Lights up in Operation mode ( Note: OFF in standby mode).
2. Blinks for 0,5 sec., to announce that a R/C infrared signal has
been received and stored.
3. Blinks continuously during:
- OCT (outdoor coil temp.) High pressure protection Mode
- Deicing in Heating Mode
4. Blinks continuously in case of FS (Float Switch) trips for high water level.
