If the communication with the air conditioner is not smooth or if the pulse signal is not detected
from the wattmeter, the error will be displayed on the LCD.
• Communication error display

- During communication error status, power consumption (gas consumption) is reflected on the
accumulative power (accumulative gas).
- No power(gas) is distributed to each indoor unit. When communication is resumed, accumula-
tive power (gas) is distributed to each indoor unit.
• No signal error in the wattmeter (gas meter)

• In the case of no signal error in the wattmeter (gas meter)
As outdoor unit power consumption (gas consumption) is low, if no pulse is displayed for a
certain time, error may be displayed. As soon as pulse is applied, error indication disap-
pears.
