Detailed description of
the objects

Project design and programming
Object: "Control value heating": 1 byte (EIS6)
The heat output is specified via this object. The object value is sent e.g. by a
room thermostat.
Telegram value
Object: "Control value cooling": 1 byte (EIS6)
The cooling capacity is specified via this object. The object value is sent e.g.
by a room thermostat.
Telegram value
Object: "Speed limitation": 1 bit (EIS1)
The fan speed can be limited to a maximum value via this object. This
prevents the fan from exceeding a specific speed e.g. at night (noise
reduction).
Telegram value
Object: "Forced operation": 1 bit (EIS1)
A fan speed and valve position can be assigned to the fan coil controller via
this object and the controller is disabled. The fan speed and valve position
can be parameterised.
Telegram value
Object: "Toggle heating/cooling": 1 bit (EIS1)
This object is visible in the operating mode "2-pipe system, heating and
cooling" i.e. the fan coil unit only has one connection for supplying hot or
cold water. Via the object, the device receives information from the building
control system about whether hot or cold water is supplied. The object
"Control value heating" or "Control value cooling" is evaluated accordingly.
The object can be inverted.
Telegram value

Inverted:
Objects: "Slave fan speed 2" to " ... 5": 1 bit (EIS1)
Via these objects, the master output controls further outputs which are used
for ventilation control. These outputs must be parameterised as slaves.
Telegram value
Object: "Slave valve": 1 bit (EIS1)
This object is visible when using a 2-pipe system i.e. there is only one valve.
The object controls a further output which in turn controls the valve. The
output must be parameterised as a "Slave". As soon as the fan is running at
speed 1 at least, the object value = "1", otherwise it is "0".
