Installation Procedure
Emergency Temperature Output (ETO) function
CAUTION
ŷ 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.
– Basically, the indoor unit 2 operates in the previous mode. [For the first time operation, it starts in 24 °C Auto mode.]
– To set more detailed operation conditions for the indoor unit 2, use the S-net Pro.

ETO operation specifications
1 Main indoor unit
– Based on the external contact control settings, the main indoor unit decides whether to generate output when
an error (indoor unit stop) occurs.
– Based on the ETO settings, the main indoor unit decides whether to generate output according to the
temperature and time conditions.
2 Sub indoor unit
– Based on the entrance control settings, the sub indoor unit decides the mode, set temperature, and fan speed
when contact inputs are given.
