scenario, the setpoint value shown or written in register 4/5 will always be
the same as the current setpoint value of the indoor unit.
o Notice that, the use of the “external temperature reference” (register 22/23)
(e.g., writing a value different from -32768 / 0x8000 in it) has the following
relevant consequences:
▪ The mechanism of “Virtual Temperature” is applied. The temperature
setpoint’s value shown by the Remote Controller or other Control
System from Daikin connected to the indoor unit may show a different
value from the value shown in register 4/5.
▪ The User is not be able to change the setpoint using any Remote
Controller from Daikin, as setpoint of the indoor unit becomes
exclusively controlled by the “Virtual Temperature” mechanism.
• AC Real temperature setpoint (R)
(register 23 – In Protocol address / register 24 – in PLC address):
As it has been detailed on the previous point, the real temperature setpoint in the
indoor unit and the temperature setpoint requested from INMBSDAI001I000 might
differ (when a value in register 22/23 – “external temperature reference” is
entered). This register always informs about the current temperature setpoint which
is being used by the indoor unit – it is also includes the temperature setpoint that
will be shown by an additional remote controller from Daikin connected to the indoor
unit, if it is present on the system.
Moreover, notice that temperature’s values of all these three registers are expressed
according to the temperature’s format configured through its onboard DIP-Switches
(See 4.3). The following formats are possible:
• Celsius value: Value in Modbus register is the temperature value in Celsius (i.e.
a value “22” in the Modbus register must be interpreted as 22ºC).
• Decicelsius value: Value in Modbus register is the temperature value in
decicelsius (i.e. a value “220” in the Modbus register must be interpreted as
22.0ºC).
• Fahrenheit value: Value in Modbus register is the temperature value in
Fahrenheit (i.e. a value “72” in the Modbus register must be interpreted as 72ºF
(~22ºC).
