NECS-ME
HFC R410A
2.6 Control unit with LCD display (standard)
The new “W3000 Base” control unit is installed on all NECS-ME
0152..0612 units.
The new “W3000SE Compact” control unit is installed on all
NECS-ME 0604..1604 units.
Main functions
: QuickMind, local and remote FWS supervi-
sion, dual set point management, etc, confi rm Climaveneta’s
commitment to continually developing its electronics technol-
ogy.
The heat pumps, moreover, are fi tted with the original Cli-
maveneta defrosting control system called “Autotuning Defrost”
which considerably reduces defrosting times, thus improving
the energy performance of the unit. Interfaces with BMS sys-
tems: METASYS®, MODBUS®, LONWORKS®, SIEMENS®,
TREND®.
Black Box
logs data relative to 200 alarm events which can be
printed with a personal computer.
QuickMind
is a special control unit which monitors the main
operating parameters, predicts system behaviour and antici-
pates unit settings in order to constantly optimise performance;
it allows both return and delivery water temperatures to be
chosen as adjustment parameters. It can reduce outlet tem-
perature fl uctuations even with a small amount of water in
the system. When, for dual-compressor chillers featuring a
maximum of 12 start-ups per hour and using a traditional ad-
justment system, the minimum recommended water content
is 5.5 l/kW. QuickMind ensures the same chiller operates cor-
rectly even with a water content of just 2.5 l/kW and considera-
bly reduces outlet temperature fl uctuations. The above graph
shows that outlet temperature fl uctuations with QuickMind are
limited to 4.3 °C as opposed to 7.54°C if the traditional adjust-
ment system were used, without even ensuring an acceptable
minimum compressor start time.
