 In order to deploy the ETO function, the MIM-B14, an external contact interface module, must be
installed in each indoor unit.
 The ETO is a concept of emergency operation of indoor units. If the indoor unit 1 (main indoor unit)
stops because of an error, the indoor unit 2 (sub indoor unit) starts to operate.
