Refer to figure 5.
Selecting usage of remote user interface
The following setting has to be made on the controller of the unit.
Refer to the the chapter “Entering the list of user parameters” in the
operation manual of the chiller on how to use the digital controller.
User parameter h8 in combination with the remote user interface
allows the user to use the remote user interface.
■ When user parameter h8 is set to 0 (= No), no remote user
interface is used.
■ When user parameter h8 is set to 1 (= Yes), the remote user
interface is used.
To select working with or working without the remote user interface,
proceed as follows:
1 Enter the list of user parameters.
Parameter code :d appears on the display.
2 Select parameter code h8 using the A and/or Z key.
3 Press the R key to switch to the parameter value.
4 Select the appropriate setting using the A and/or Z key.
5 Press the R key to return to the list of parameter codes.

6 To adjust or to consult other user parameters before saving the
modifications, select another user parameter using the A and/
or Z key and then repeat from instruction 3 onwards.
7 To save the modifications, press the E key. To cancel the
modifications wait approximately 40 seconds.
In the first case, the controller saves the changes, leaves the list
of user parameters and returns to normal operation, displaying
the inlet water temperature.
In the second case, the display starts flashing. Approximately
40 seconds later, the controller leaves the list of user
parameters without saving the modifications. The inlet water
temperature reappears on the display.
