1 messana box submittal Job Designer Contact mbox is a powerful control unit specifically designed for hydronic radiant cooling and heating systems with different terminals: ceiling panels, radiant floors, hydronic fan coils as well as air handlers and third-party VRV systems. It is assembled with industrial grade components for commercial and residential high-end applications. The unit regulates the building s energy usage by activating energy sources (Heat pumps, chillers and boilers) and circulator pumps, modulating the radiant fluid flow through 3-way mixing valves and controlling the zone terminals with modules. It features an unique technology to efficiently control the Domestic Hot Water (DHW). mbox is based on a x86 architecture (Intel Atom E3800) with inus O (Debian). It acts as the logical main unit, web server, gateway and communication module. mbox fully integrates with the Messana web and mobile app (io and Android) providing a unique climate control platform (mcontrol) developed with more then 20 years of experience in radiant cooling and heating technology. Features Industrial PC x86-based platform (Intel Atom E3800) with inux O (Debian); programmable I/O module (Modbus or BACet) designed in collaboration with Emerson; Ethernet connection to zoning modules, room and Ethernet switches; R485 master and slave serial connections for, comfort sensors, Air Treatment Units and other Modbus RTU devices; remote Internet access with the Messana App and web interface; additional Graphic Display (optional). ize and weight 1 size W1: 14 inches (357 mm) W2: 12 inches (305 mm) D: 3 1/2 inches (90 mm) H: 16 inches (410 mm) D weight 14.5 lb (6.5 kg) W1 W2 H Casing Mounting type Fixed mounting brackets Protection grade EMA 13 (IP65) Color and finish Arctic white metal enclosure Environmental requirements Operating ambient temperature 36 to 110 F (2 to 45 C) Relative humidity (indoor use only) <90%, non condensing Optional Graphic Display CD with 240x96 px ovember

These two signals, along with a shield HD (often referred to as GD) for reference, are the serial BU. The mbox act as a master and the other Modbus units are slaves. To achieve bi-directional communications the BU is shared between transmitting and receiving. Polarity between the D+ and D- signals must be respected. HD (from the ZOE BU) terminal must be connected to the shield of the serial bus cable (for foil shielded cable, use the shield drain wire) to provide shielding against induced noise. The shield must be connected at one end only. Without the HD connection, reliability of the protocol can be significantly degraded. Always connect the shield drain wire to HD only on the mbox side. Do not connect the shield on any other Modbus device to GD (or HD).

5 Inputs / Outputs contacts ZOE BU (D+, D-, HD,, ) Zone Bus is a R485 bus used to communicate with room sensors (up to 12) over Modbus RTU protocol. In typical installations the sensors are installed directly on the module. HD terminal must be connected to the shield of the serial bus cable (for foil shielded cable, use the shield drain wire) to provide shielding against induced noise. The shield must be connected at one end only. ZOE BU HD D+ D Without HD connection, reliability of the protocol can be significantly degraded. Always connect the shield drain wire to the mbox HD terminal and make sure the continuity is maintained on each split connection by twisting together the shield drain wires of the two shielded cables. and terminals are used to supply DC power to the sensors attached on the BU. Up to 12 sensors can be installed with max 300ft of wire (22AWG). D+ and D- are the signal bus terminals. These two signals, along with the shield (HD), are the serial BU. The mbox act as a master and the sensors are slaves. To achieve bi-directional communications the BU is shared between transmitting and receiving. Polarity between the signals D+ and D-, must be respected. The last sensor on the bus must be terminated by setting the dip-switch ID#9 to O. The mbox module can also be installed in the middle of the bus with two different terminated branches. max 300ft n 12 max 300ft m < n max 300ft n 12 ID 1 ID n Termination O ID m Termination O ID 2 ID 1 mbox ID m+1 ID m+2 ID n Termination O AO1 MIX (,, Y), AO2 MIX (,, Y), AO3 AUX, AO4 AUX 0-1 or 2-1 programmable opto-insulated analog outputs for controlling motorized mixing valves, servo motors, actuators, fan-coils, and other analog devices.

AO1 MIX AO2 MIX AO3 AUX AO4 AUX Y Y Y Y, are the terminals to supply power to the valve actuator. Y is the 2-1 (or 0-1) terminal to control the position of the valve. Y can be programmed as a 0-1 or 2-1 analog output. AO MIX default value is 2-1. BK RD WH OG Belimo actuator models RB24-R-T ARB24-R-T 0-1 Analog Messana suggests the use of the Belimo B3 series 3-Way mixing valves with 2-1 proportional control actuators: RB24-R-T (B307-B325 valves) and ARB24-R-T (B329-B352 valves). AO3 AUX and AO4 AUX are two general purpose analog outputs., Y are the 0-1 (or 2-1) signal terminals to control analog devices (servo motors, actuators, fan-coils, etc.).

AI TC AI TC AUX UPPY RETUR AI3 AI4 AI5 AI6 UPPY terminals are used for supply fluid TC temperature probes. R RETUR terminals are used for return fluid TC temperature probes. The UPPY thermistors must be installed after the circulator pump. AI TC AUX (AI3, AI4, AI5 and AI6) are general purpose additional analog inputs preprogrammed as TC to measure other temperatures (buffer tanks, energy sources supply, DHW tank, etc.). R T T T AI terminals are used for TC temperature probes. Analog Inputs can be reprogrammed as PTC, 0-20mA, 4-20mA, 0-1, 0-1V or 0-5V or digital inputs. Do not use PT1000 temperature probes. Use only 3435 K 10 kohms TC thermistors. DI1 AUX Digital Inputs (DI) are opto-insulated dry contacts. DI are used to communicate the status of external devices to the mbox module. DI can be programmed to be triggered by normally open (O) or normally close (C) external contacts. By default a DI is preset to work with a O contact. In case of event, an external contact is closed and acknowledged by the DI. DI AUX DI1 is a dry contact digital input for external devices (alarm system, fire alarm, window sensor, presence sensor, etc.). It can also be used with an external switch to select the system mode between heating and cooling or to force the device O and OFF. DI1 mbox offers one digital input, DI1, pre-wired on the terminal blocks on the DI bar. Additional 10 Digital Inputs (DI2-DI11) are available directly on the embedded Emerson I/O controller and need to be wired directly on the push-in connectors located on the controller.

It is a combination of both radiant ceiling and radiant floor with 2 fan-coils in integration, one in the living room (Modbus #1) and one in the master bedroom (A 0-1). The system features 11 zones (with both radiant cooling and heating) controlled with one 12 dedicated to the 1st floor (6 zones, 3 to 8) and on 8 (4 zones, 15 to 21) for the 2nd floor. There is also one T/H sensor (#2) attached to an installed in the guest room and one (#1) installed in the mechanical room only for monitoring temperature and humidity (no zoning). A Heat Pump is the primary source to provide heating and cooling with a second stage chiller for cooling and a second stage gas fired boiler for heating. The boiler is also dedicated to the Domestic Hot Water system that features a recirculation system. Two Air Treatment Units (one per floor) with HRV are dedicated to control the air quality (IAQ) including the humidity.
