ATTENTION:
In case that ambient temperature of chilled/warm water circulation system is lower than that of
the Unit installation place, Thermostat for ambient temperature shall be introduced in the place
with the lowest temperature and shall be connected to pump operation order circuit in parallel.
Saving energy priority
mode, silence priority
mode (night shift), only

2. Automatic release of antifreeze control
This operation is released only when ambient temperature is over 4°C.
4.15. Saving energy priority mode, silence priority mode (night shift),
only cooling
It is possible to select 3 types of fan control depending on the installation place or use
applications
1. Standard mode
Fan control (revolution number control)
−
suitable to ambient temperature.
Good balance from the view of saving
−
energy and silence.
2. Saving energy priority mode
Fan control (revolution number control)
−
tries to keep discharge pressure as low as
possible at night or during midterm period.
Saving energy has the priority to silence.
−
3. Silence priority mode (night shift)
Smaller revolution number for silence
−
purpose at night or during midterm period.
Little fan noise mode.
