Operation check
•Temperature sensor that fits the specification must be installed in the SA duct and RA duct.
(Specification: -50~50°C/ AC 24V / DC 0~10V)
•Install the temperature sensor only for the SA/RA duct and Dip switch does not need to be set.
•Depending on the installation site, if the optional sensor is applied, set the dip switch according to the setting method.
•Be careful of Dip switch setting according to whether Outdoor unit is connected or not.
•When connecting Outdoor unit, make sure to set Rotary switch differently.
•After completing the installation of CONTROL KIT, always set the address of Outdoor unit.
■This order can change depending on the construction site. Therefore please read the installation manual prior to the applicable work.
