Programmable zone controller
mZone is a fully programmable zone controller available in two different sizes: 8 and 12 zones.
It is integrated with the Messana climate control platform developed with more then 20 years of experience in
radiant cooling and heating technology. It connects with mBox via Ethernet or, alternatively, via serial bus (RS485
slave) and it interfaces with the Messana web and mobile App.
mZone is powered with a dedicated Emerson programmable I/O module based on a high performance 32-bit ARM9
(200 MHz) microprocessor.
mZone integrates a 24Vdc switching power supply (120-230 Vac with 85W output power for mZone 8 and 120W for
mZone 12) and does not require an external transformer to drive thermal actuators. With a proprietary staggered
activation technology it can drive up to 34 thermal actuators (with mZone 12)
The mZone module connects up to twelve mSense room sensors (mZone 12) or up to eight mSense (mZone 8) in
daisy-chain via serial bus (RS485 master zone bus).
mZone modules are typically installed next to the manifolds to control the flow or the radiant fluid by activating the
thermal actuators installed on the manifold loops or the zone valves.
mZone can also control a local mixing and pumping station with a PID close control loop.
Based on the current supply fluid temperature, mZone adjusts the position of a proportional 3-way mixing valve
and modulate the fluid temperature. Compared to a traditional On/Off control, this technology allows to deliver just
enough heat (or cool, by heat extraction) to avoid temperature swings and oscillations.
With the PID control logic the radiant system always achieves optimized performance in terms of energy efficiency
and comfort maintaining an accurate and uniform indoor temperature.
mZone is designed for 2-pipe as well as for 4-pipe distribution systems for simultaneous heating and cooling
demand. Can also control heating and cooling seasonal changeover (manually or following a schedule) or
automatic changeover based on the internal load and external conditions (adaptive-comfort).
It works also with hybrid radiant/forced-air cooling and heating systems. Can activate fan-coils when supplemental
convective integration is necessary.
One of the features that distinguishes the mZone controller, compared to similar products available on the market,
is the vast range of both analog and digital input/outputs ports to connect with external devices. Most of the I/Os
are fully configurable and are opto-insulated.
As an optional, mZone can be equipped with a graphic display that allows reading of all the parameters (supply
and return temperature, flow and pressure, zone status, zone temperature and humidity) and to perform manual
installation test (pump and zone activations, force zone on or off, mixing valve setup).
