9 Configuration
9.1 Facility setting
Use this function for cooling at low outdoor temperature. This
function is designed for facilities such as equipment of computer
rooms. NEVER use in a residence or office where people occupy the
space.
9.1.1 To set the facility mode
When cutting jumper J6 on the PCB, the operation range will expand
to –15°C. The facility mode will stop if the outdoor temperature drops
below –20°C and resume when the temperature rises again.
