When a
“1”
value is sent to the
Control_
communication object,
Heat mode
will be enabled in the indoor unit, and the
Status_
object will return this
value.
•
When a
“0”
value is sent to the
Control_
communication object,
Cool mode
will be enabled in the indoor unit, and the
Status_
object will return this
value.
4.2.3 Enable PID-Compat. Scaling Mode Objects
This parameter shows/hides the
Control_ Mode Cool & On
and
Control_ Mode Heat & On
communication objects.
o
If set to
“no”
the objects will not be shown.
o
If set to
“yes”
the
Control_ Mode Cool & On
and
Control_ Mode Heat & On
objects will
appear.
•
These objects provide compatibility with those KNX thermostats that control
the demand of heating or cooling by using scaling (percentage) objects. In
these thermostats, the percentage demand is meant to be applied on a fluid
valve of the heating / cooling system.
•
ME-AC-KNX-1i device does not provide individual control on the internal parts
of the indoor unit (as can be its compressor, refrigerant valves, etc). Rather,
it provides the same level of control as a (user) remote controller.
•
Objects “Control_ Mode Cool & On” and “Control_ Mode Heat & On” intend to
bring compatibility between thermostats oriented to the control of custom
heating / cooling systems and ready-made AC indoor units, by applying the
following logic:
•
Whenever a non-
zero value (>0%) is received at “Control_ Mode Cool
& On”, indoor unit will switch On in C
OOL mode.
•
Whenever a non-
zero value (>0%) is received at “Control_ Mode Heat
& On”, indoor unit will switch On in HEAT mode.
•
Lastest updated object will define the operating mode
•
Indoor unit will switch off only when both objects become zero (0%)
–
or w
hen an OFF is requested at object “0. On/Off [DPT_1.
001 -
1bit]”
Important:
These objects function is only to send On/Off and Cool/Heat to the indoor
unit. The PID (Inverter system) is calculated by the indoor unit itself. Please consider
introducing an appropriate PID configuration to the external KNX thermostat to not
interfere the indoor unit PID.
