(Lower limit) 16ºC 17ºC … 31ºC 32ºC (Upper limit)
Up / Increase
Down / Decrease

4.4.2 Ambient Ref. Temp. is provided from KNX

This parameter shows/hides the Control_ Ambient Temperature communication object which lets you use an ambient temperature reference provided by a KNX device.

• If set to “no” the object will not be shown.

• If set to “yes” the Control Ambient Temperature object will appear. Meant to be enabled when you want the temperature provided by a KNX sensor to be the reference ambient temperature for the air conditioner. Then, the following formula applies for the calculation of real Control Setpoint Temperature sent ot the AC unit:
  “AC Setp. Temp” = “Ambient ref. Temp” – (“KNX Amb. Temp.” – “KNX Setp Temp.”) Temp”)

  • AC Setp. Temp: AC indoor unit setpoint temperature
  • Ambient Ref. Temp: AC indoor unit return temperature
  • KNX Amb. Temp.: Ambient temperature provided from KNX
  • KNX Setp. Temp: Setpoint temperature provided from KNX
    As an example, consider the following situation:
    User wants: 19ºC (“KNX Setp. Temp.”)
    User sensor (a KNX sensor) reads: 21ºC (“KNX Amb Temp.”)
    Ambient temp. read by Haier system is: 24ºC (“Ambient Ref. Temp”)
    In this example, the final setpoint temperature that INKNXHAI0–C000will send out to the indoor unit (shown in “Setp. Temp.”) will become 24ºC – (21ºC – 19ºC) = 22ºC. This is the setpoint that will actually be requested to Haier unit.
    This formula will be applied as soon as the Control Setpoint Temperature and Control Ambient Temperature objects are written at least once from the KNX installation. After that, they are kept always consistent.
    Note that this formula will always drive the AC indoor unit demand in the right direction, regardless of the operation mode (Heat, Cool or Auto).

• If set to “no” the objects will not be shown.
• If set to “yes” the Control and Status Control Mode objects for No Central, LIFO (Last Input First Output), Central Controller, Lock Central Controller will appear.

4.5.1 Initial state of Control Mode

This parameter sets the initial value for the Control Mode: No Central, LIFO (Last Input First Output), Central Controller, Lock Central Controller or Do not initialize.

Figure 4.24 Parameter detail

• If set to “Apply same initial state to all Indoor Units” , the parameter option selected will apply to all indoor units.
• If set to “Initial state for each Indoor Unit might differ” , you will be able to set this parameter for each Indoor Unit individually.

4.6 Addressing of Indoor Units
