In case of Input voltage ,
● Input voltage (equally divided upper and lower setting temperature limits)
(factory default)
・ Performed in the input range of 0 to 10 V DC (lower setting
temperature limit to upper setting temperature limit).
・ Relationship between setting temperature and voltage is as the diagram below.
・
Upper and lower temperature setting limits may vary according to the indoor units and
operation mode.
Refer to the relationship between setting temperature and voltage, described in (example)
3-1 "Operation mode of a typical model [lower limit to upper limit]".
・ Set the Set temperature input switch S4 to "0 to 10 V" (factory default)

● Select the temperature setting control method from the following 3 types.
・ Input voltage (equally divided upper and lower setting temperature limits)
・ Input voltage (fixed voltage)
・ Input resistance
・ Performed in the input range of 0 to 10 V DC.
・ The effective range of the setting temperature is 2.2 V to 10 V (11 °C to 50 °C).
Remote controller cannot be used for temperature in this range.
・ When the input exceeds the upper or lower setting temperature limits, it is set to the upper or
lower limits.
For example, in case of air-conditioning (cool) [18 °C to 30 °C], if the voltage is below 3.5 V,
the temperature is set to 18 °C, and if over 6.2 V, to 30 °C.
・
To set the temperature using remote controller, set the input voltage below 1.9 V.

・ Temperature setting (1 °C step) is performed in the range of 0 to 140 Ω .
・ Relationship between setting temperature and resistance is as the diagram below.
・ Upper and lower temperature setting may vary according to the indoor units and operation mode.
Refer to the relationship between setting temperature and resistance, described in (example) 3-1
"Operation mode of a typical model [lower limit to upper limit]".
・ Set the Set temperature input switch S4 to "0 to 140 Ω ".
