figure 35 o If set to “no” the object will not be shown.
o If set to “yes” the Control_ Setpoint Temp +/- object and a new parameter will appear.. DPT type for +/- Setp Temp object
This parameter lets choose between the datapoints 0-Up / 1-Down [DPT_1.008] and 1- Decrease / 1-Increase [DPT1.007] for the Control Setpoint Temp +/- object. Carrier XCT-7 Variable Refrigerant Flow Controls - figure
37 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. o If set to “no” the object will not be shown.
o 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.”)

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 system is: 24ºC (“Ambient Ref. Temp”)
In this example, the final setpoint temperature that 40VCBK17/27/37FQEEwill 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 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).

This parameter shows/hides the Control Control Mode and Status Control Mode communication objects which lets you change the indoor unit control: No Central, LIFO (Last Input First Output), Central Controller and Lock Central Controller. Carrier XCT-7 Variable Refrigerant Flow Controls - figure
40

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. Carrier XCT-7 Variable Refrigerant Flow Controls - figure
41

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 Carrier XCT-7 Variable Refrigerant Flow
Controls - figure 42 In this section you will be able to set the AC addressing for each AC unit present in the installation.

Modbus GW address of ACxx refers to the addres of the Communication Addapters.
