Control Method
11) AUTO operation
An auto operation sets the water temperature TSC_F depending on the outside 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" "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 changed in the ±5K range. (FC_27)
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.
