*1. By the Wired remote controller (Touch panel), external output indication is transferred to Economizer logic mod-
ule through the indoor unit.
● Economizer Logic module is required for Economizer operation.
● Economizer Logic module judges the amount of outdoor air intake depending on indoor unit output at operating
condition, occupied status and outdoor temperature etc.
● Cooling operation by only free cooling is possible.
