Caution:
When operation stops suddenly and the operation lamp blinks, it could be "operation mode conflict". Check followings; Are the operation modes all the same for the indoor units connected to multi system outdoor unit? If not, set all the indoor units to the same operation mode and confirm that the operation lamp is not blinking. Moreover, when the operation mode is automatic, set all the indoor unit operation mode as "cooling" or "heating" and check again if the operation lamp is normal. If the lamp stops blinking after the above steps, there is no malfunction. ∗ Operation stops and operation lamp blinks only for indoor unit which different operation mode is set later. (The first set operation mode has priority.)
