Making control simple and powerful
Controlled by mBox
mZone connects to mBox (via
Ethernet or serial bus RS485).
mBox is the brain of any Messana
climate control platform. It is
based on a Linux embedded
system and it operates advanced
radiant cooling logics.
WAGO CAGE-CLAMP®
WAGO terminal blocks with
CAGE CLAMP® connection
technology. It makes connections
to the mZone safe, quick and
easy. It requires a small screw
driver to open the clamp and the
wire (strained or solid conductor)
is inserted in the clamp.
Connect with mSense
mZone controls up to 8
(mZone 8) or 12 (mZone 12)
different zones. Each zone
is monitored with the new
Messana mSense room comfort
sensor that measures operative
temperature, relative humidity,
and indoor air quality.
Graphic display (optional)
mZone can be equipped with
a graphic display to show I/O
status and allow the operator
to troubleshoot the system and
perform basic tests on thermal
actuator, pumps, mix valve,
actuators etc.
Powered by Emerson
mZone modules are powered
by a dedicated Emerson
programmable I/O controller.
Emerson is the world’s leading
provider of HVAC control
solutions for residential, and
commercial applications.
Opto-insulated I/Os
Opto-isolators provide a safe
interface to protect internal
circuits from excessive or
transient voltage spikes that
could potentially damage the
device.
PID temperature control
mZone can control one or two
mix/pump stations. With a
PID (Proportional Integrative
Derivative) control logic, it
modulates the fluid temperature
to optimize comfort and energy.
Programmable analog I/Os
Programmable I/Os allow to
integrate with different types
of hvac devices. Analog inputs
are configurable as NTC, PTC,
0-20mA, 4-20mA, 0-10V, 0-5V,
0-1V, or DI. Analog outputs can
be set as 0-10V or 4-20mA.
PID
Staggered activation
Messana has developed an
optimization algorithm that
stagger the opening of thermal
actuators to minimize the
maximum current rush. This
technology allows to increase
the number thermal actuators
(up to 34 with mZone 12).
