Step 14 optional : Setting the Emergency Temperature Output (ETO) function
Emergency Temperature Output (ETO) function (for the multi system, this
function is not supported.)
CAUTION
• 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.
