We recommend plugging the jumpers on the Multi-Heating actuator for each channel to „Heating
only“, “Cooling only” or “Heating and Cooling” depending on how you use the channels in the
Home-Manager or intelligent device. That will make sure that all channels are only controlled when
their desired operation type is active.
Information about the valve regulation of the Multi-Heating actuator:
The electrical outputs of the Multi-Heating actuator are PWM controlled (Pulse width modulation).
A PWM cycle lasts 15 minutes and the ON and OFF time is depending on the difference of Set-
and actual-temperature. For example if there is a high difference the Output will be ON for about
11 minutes and OFF for 4 minutes. If there is a low difference it is the other way round. The
maximum ON time for the output is 12 minutes and the minimum time is 1 minute (if it’s lower than
that it will not switch ON at all). For every new value of Set- and actual temperature the regulation
will be recalculated.
The connected electrical valves have a specific inertance and will not close immediately when they
are switched OFF.
USB-RF-Communication Stick
The USB-RF-Communication Stick is used to enable the Eaton wireless system to communicate
with the PC, e.g. using display software or a different control system.
The connection to other systems will be dones exclusively over USB.
The USB-RF-Communication Stick partially replaces the old Communication interface
(CKOZ-00/03). The only difference is that the old interface can also communicate by RS232.
However it does not replace the configuration interface that is used by the MRF. The configuration
of a project in the comfort mode is only possible using the Configuration interface (RS232 gateway
or USB-RF-Configuration Stick).
Making connections:
The connection to other xComfort devices is done using single datapoints.
If you draw a connection from a xComfort device to the USB-RF-Communication Stick the
datapoint window will pop up. You can enter the desired datapoint number for the assigned device.
If you connect multiple actuators to the same datapoint it will simply generate multiple entries for
this datapoint.
Create datapoint list:
Using the Popup-menu of the USB-RF-Communication Stick you can select the function “Create
datapoint list” to create a list of all connected devices for all datapoints
You either have the option to save the list in a file or transfer it directly to the external memory of
the device by RF.
