Operation Mode
and Control
Method
12) AUTO operation
An auto operation sets the water temperature TSC_F depending on the outside air temperature TO.
1) How to operate
• Pressing the remote controller [ZONE1, 2] button and then the [AUTO] button starts AUTO operation for heating.
• 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 60 °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.
<ZONE1>
• An operation starts at the set temperature of straight -line approximation for the following: water temperature A °C
with the outside temperatureT0 °C, B °C with T1 °C, C °C with T2 °C, D °C with T3 °C, and E °C with 20 °C.
<ZONE2>
• Set temperature of the ZONE2 can be selected from two methods (FC_A2). One is a percentage of ZONE1, the other
is a fixed value.
FC_A2 = "0" : Percentage method that is set by FC_31.
FC_A2 = "1" : Fixed value method that is set by FC_A3, A4 and A5.
However, it is automatically controlled the set temperature of ZONE1 to be the ZONE2 or more.

ZONE 2
80 % (FC_31) of ZONE1
FC_A2=0 Percentage method
Auto-Curve in ZONE2 shows 80% (FC) of that of ZONE1,
the water temperature setting does not fall below 20 °C.
The ZONE2 set temperature A' °C with the outside
temperature T0 °C, B' °C with T1 °C, E' °C with 20 °C.
