■
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.
