and Control
Method 12) AUTO operation
An auto operation sets the water temperature TSC_F depending on the outside air temperature TO by following the table below.
1) How to operate
• Pressing the remote controller [ZONE1, 2] button and then the [AUTO] button starts AUTO operation for heating. An
operation starts at the set temperature of straight -line approximation for the following: water temperature 40°C with
the outside temperature -20°C (FC), 35°C with -10 °C (T1)(FC), 30°C with 0°C (FC), 25°C with 10°C (T3), and 20°C
with 20°C (TC).
• For 2-temperature control, although Auto-Curve in ZONE2 shows 80% of that of ZONE1 (FC), the water temperature
setting does not fall below 20°C.
• During an AUTO operation, pressing again the [AUTO] button returns to the usual manual set heating operation.
• The remote controller displays "A" as the temperature during an AUTO operation.
(When 2-temperature control is enabled, the remote controller displays "A".)
• Long-pressing the [AUTO] button during an AUTO operation activates the Auto-Curve FC change mode, enabling
the set Auto-Curve water temperature to be shifted by ±5K range (FC_27). When using the auto curve shift function
please note the maximum and minimum water temperature at 55°C and 20°C respectively.
• Even if the temperature setting is changed during an AUTO operation, the operation continues.
• An AUTO operation works with a heating operation only, not with a cooling or a hot water supply operation.

13) Night time low-noise operation
A night time low-noise operation reduces operation frequency and the number of outdoor fan rotations for a certain period
during night time as noise control for urban operation.
Maximum operation frequency 40.2 Hz (Hot water supply/ Heating/ Cooling)
Maximum fan tap
460 rpm (803H-E)
500 rpm (1103H-E, 1403H-E)
(1103H8(R)-E, 1403H8(R)-E, 1603H8(R)-E)
The night time low-noise operation is enabled/ disabled by changing the remote controller FC_09.
<How to set> - Refer to “11. Night time Low-noise Setting” on page 139.
1) Press the TEMP.
and TEST button at the same time for 4 seconds or longer. (Shifted to the night time low-
noise setting mode)
The Code No. field displays "09", and the DATA "0000",
, and being displayed blink.
2) Press TIME to set enable "1" or disable "0".
Pressing SET change DATA and display to be lit and the setting is confirmed.
(When "1" as enable is set, the night time low-noise setting is enabled, the control starts at the set start time.)
3) Press TEST to exit the night time low-noise time setting mode. The and goes out, returning to its
original status.
