Applications and Functions
■
When the tenant power supply (indoor unit power supply) is turned off, this kit converts the input voltage (24 V AC) to a DC voltage and supplies a low voltage
to the indoor unit.
Furthermore, it transmits a signal to notify that the indoor unit power supply has been turned off.
The LCD of the wired remote controller turns off and becomes inoperable.
Applicable indoor units
4-way Air Cassette Type, Concealed Duct Standard Type, Slim Duct Type, Under Ceiling Type, Console Type,
High Wall Type, Concealed Duct High Static Pressure Type, Floor Standing Type, Floor Standing Cabinet Type,
Floor Standing Concealed Type
CAUTION
Install Slim Duct Type and Concealed Duct High Static Pressure Type (4 series) so that there is gravitational drainage.
(For details on gravitational drainage, refer to the installation manual of the indoor unit.)
Using a drain pump will cause a water leak.
