DISPLAY Menu
Note:
This window clearly displays the state of the
plant. Two different synoptics are available
to represent the plant’s operating principle
in a more appropriate manner, which can be
selected from the Setup menu, page 4. Enable
display circuit 1/2
Note:
IThe primary circuit is represented in this synop-
tic in blue and the secondary in red, separated by
a hydraulic disconnecting device in black
SIW: return water temperature to the primary. It
is read by the Multichiller
SUW, SUW2, SUW3: delivery temperatures to
the secondary circuit. Up to 3 branches of the
secondary circuit can be managed for secon-
daries with variable chiller. They are read by the
Multichiller.
FL, FL2 FL3: used to enable reading of the res-
pective probes for delivery to the secondary, if
the flow meter contact is open it is not taken into
consideration when adjusting the temperature
of the respective probe. They are read by the
Multichiller.
SUW chiller 1-9: the temperature of the water
exiting the chiller is stated at the side of the icon
of every chiller present and is read via serial. In
the case of machines from the following series
NRA, NRC, NLW and NBW it is the only chiller
water evaporator exit probe; in the case of RV,
NSB, NW, WSB machines it is the Master card
evaporator exit probe B5.
Chiller state 1-9: an icon is visualised that is also a
touch screen key for each chiller from 1 to 9 with
the following meaning:
Chiller not present
Flashing = chiller ON
Fixed = chiller standby
Chiller with circuit in alarm
Chiller with all circuits in alarm
Chiller with which it is not possible
to communicate
By pressing the icon key of each chiller,
access the visualisation menu of the details
of the relative chiller. This page appears for
a few seconds during loading of the data if
the chiller is present. If the chiller is not pre-
sent (the icon of a blue square is pressed)
this page remains indefinitively.
