Direct and user parameters
The digital controller provides direct and user parameters. The direct parameters are important for the everyday usage of the unit, e.g. to
adjust the temperature setpoint or to consult actual operational information. The user parameters on the contrary provide advanced features
such as adjusting time delays or disabling the buzzer. Each parameter is defined by a code and a value. For example, the parameter used to
select local or remote on/off control has code h7 and value 1 or 0.
User interface EUWAC5-10FZ
The digital controller consists of a numeric display, four labelled keys which you can press an four LEDs providing extra user information.
Digital controller
Keys provided on the controller.
Each key, except for the lower left key, combines two functions:
m / k,o / i and b / c. The function
carried out when the user presses one of these keys depends on
the status of the controller and the unit at that specific moment.
m
Key, to enter the scroll list of user parameters, to confirm
a parameter modification and to return to normal
operation.
k
Key, to de-activate the buzzer in the case of an alarm.
o
Key, to scroll through the list of direct or user parameters
or to raise a setting.
n
Key, to enter the scroll list of direct parameters or to
switch between a parameter’s code and its value.
b
Key, to start the unit in cooling mode or to switch the
unit off when cooling mode is active.
c
Key, to scroll through the list of direct or user parameters
or to lower a setting.

LEDs provided on the controller:
The controller provides five LEDs one of which, the left l
LED, is not used.
l
LED, indicates the status of the compressor.
The LED does not light up when the compressor is not
active, blinks when the compressor cannot start up
although extra load is requested (e.g. timer active) and
lights up permanently when the compressor is active.
b
LED, indicates that cooling mode is active.
s
LED, indicates that the value on the numeric display
should be multiplied by 100.
Note:
– Temperature readout tolerance: ±1°C.
– Legibility of the numeric display may decrease in direct sunlight.
