4.1 - Touch screen display
SmartVu
is a 4.3-inch (standard) or 7-inch (optional) colour
TM
touch screen with quick display of alarms, current unit operating
status, etc. It allows for web connectivity and custom language
support (control parameters displayed in the language selected
by the user).
■ If the touch screen is not used for a while, the screen backlight
will be turned off. The control system is always active and
the operating mode remains unchanged. Press anywhere on
the screen and the Home screen will be displayed.
■ It is recommended to use a stylus for the navigation via
the touch screen (not provided with the controller).
4.2 - Home screen (synoptic view)

Please note that the picture of the chiller is for illustration only and
it may differ from the actual look of the chiller that is available on
field. The image displayed on the home screen represents the
whole series of 61XWHZE chillers.
The home screen allows you to monitor basic information about
the operation of the chiller and its working conditions.

Description
Setpoint: This parameter is used to display the currently
selected setpoint. Press the icon to modify the setpoint
(possible only when logged in!, see section 5.7).
Unit capacity: The gauge shows current unit capacity.
Pump status: Press the icon to go to pump parameters.
The pump image is animated when the pump is "on".
Leaving Water Temperature: This parameter shows
current leaving water temperature.
Entering Water Temperature: This parameter shows
current entering water temperature.
4.3 - Circuit view
To access the circuit view, please press the Circuit view button
(see section 4.6).
The circuit view is available from:

Description
(1) Compressor is used to squeeze the compressor
refrigerant gas and turn it into high pressure gas. The image
is animated when at least one compressor is running in the
circuit.
(2) Condenser is a heat exchanger used to cool down the
vapour and condense the gas into a liquid.
(3) EXV is used to control the flow of refrigerant into the
evaporator. The circuit view displays the current position of
the electronic expansion valve.
Valve position is given in %, where 0% means closed
position and 100% means open position.
(4)
Evaporator absorbs heat from the air and it does the
opposite of the condenser, i.e. the evaporator converts
the liquid into gas.
Circuit capacity: The gauge shows current circuit capacity.
Leaving Water Temperature: This parameter shows
current leaving water temperature.
Entering Water Temperature: This parameter shows
current entering water temperature.
4.4 - Information message box
The information displayed in the status bar at the bottom of
the screen includes relevant messages related to actions taken
by the user.
