Each digital outputs is a 24VDC normally open contact with max 5Amps. It is possible to connect up to 3 actuators to each Digital Output with a maximum of 10 actuators for mZone 8 and 17 actuators for mZone 12.

The maximum number of thermal actuators supported by one mZone can be expanded from 10 to 18 (mZone 8) and from 17 to 34 (mZone 12) using the staggered activation logic. This function must be programmed in the mBox unit that controls the mZone.

Do not connect more then 3 Messana two-wire (1W) thermal actuators for each digital output and do not drawn more then 5 Amps for each digital output.

DO8 mZone 8 digital output DO8 can be used either for the actuation of zone number 8 or as a power relay DO8 (PWR) to activate a circulator pump or other high voltage device. The DO8 (PWR) power relay can also be rewired as a dry contact or 24VDC contact.

ZONE THERMAL ACTUATORS (24VDC) (mZone8DO1-DO8 and mZone12DO1-DO12)

mZone 8 features eight digital outputs (DO1-DO8) and mZone 12 twelve digital outputs (DO1-DO12), dedicated to the activation of zone thermal actuators or zone valves.

ZONE BUS (SHD, 0V, 24V, D+, D-)Zone Bus is a RS485 bus used to communicate with mSense room sensors (up to 12) over Modbus RTU protocol.

SHD is dedicated to the connection of the serial communication cable shield (at one end only) and provides shielding against induced noise. If the serial cable has is a foil shield, then use the shield drain wire.

Without SHD connection, reliability of the protocol can be significantly degraded. Always connect the shield drain wire to the mZone SHD terminal and make sure the continuity is maintained on each mSense split connection by twisting together the shield drain wires of the two shielded cables.

0V and 24V terminals are used to supply 24VDC power to the mSense sensors attached on the BUS. 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 (SHD), are the mSense serial BUS. The mZone acts as a master and the mSense sensors are slaves. To achieve bi-directional communications the BUS 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 ON.

The mZone module can also be installed in the middle of the bus with two different terminated branches.

0-10VAnalog Device

AO1 MIX (available on both mZone 8 and mZone 12) is typically used to control a motorized proportional mix valve to adjust the radiant fluid temperature.

0V, 24V are the terminals to supply power to the valve actuator. Y is the 2-10V (or 0-10V) signal terminal to control the position of the proportional mixing valve.

Y can be program as a 0-10V or 2-10V analog output. AO MIX default value is 2-10V.

Messana suggests the use of the Belimo B3 series 3-Way mixing valves with 2-10V proportional control actuators: LRB24-SR-T (B307-B325 valves) and ARB24-SR-T (B329-B352 valves).

mZone12AO2 AUX (available only on mZone 12) is a general purpose analog output.

0V, Y are the 0-10V (or 2-10V) signal terminals to control analog devices (servo motors, actuators, fan-coils, etc.).

Y can be program as a 0-10V or 2-10V analog output. AO AUX default value is 0-10V..

AO1 MIX (0V, 24V, Y) and mZone12AO2 AUX0-10V or 2-10V programmable opto-insulated analog outputs for controlling motorized mixing valves, servo motors, actuators, fan-coils, and other analog devices. Can also be reprogrammed as 4-20mA.


AI NTC (SUPPLY / RETURN)Analog Inputs for temperature probes (NTC 10kΩ@25°C Beta 3435). Can also be reprogrammed for pressure sensors, flow meters, feedback signals.

AI NTC are dedicated to NTC probes to measure supply and return temperatures of the radiant fluid at the manifold at the manifold.

S SUPPLY terminals are used for supply fluid NTC temperature probe.

R RETURN terminals are used for return fluid NTC temperature probe.

The SUPPLY thermistors must be installed after the circulator pump.

Analog Inputs can be reprogrammed as PTC, 0-20mA, 4-20mA, 0-10V, 0-1V or 0-5V or digital inputs.

Do not use PT1000 temperature probes. Use only 3435 K 10 kOhms NTC thermistors.

Notes

1. Digital Outputs mZone8DO1-DO8 and mZone12DO1-DO12 are normally open 24VDC wet contacts (max 5Amps). They are used control zone valves and/or thermal actuators (24VDC). Digital Outputs mZone8DO8 and mZone12DO13-DO15 are used to control the 24VDC coils of the miniature power relays labeled mZone8DO8 (PWR) and mZone12DO13-DO15 (PWR). mZone8DO8 can only have one usage: either DO8 (24VDC) or power relay DO8 (PWR).

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 ON and OFF.

mZone 8 do not offer any digital input pre-wired on the terminal blocks on the DIN bar. Additional 11 Digital Inputs (DI1-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.

mZone 12 offers one digital input, DI1, pre-wired on the terminal blocks on the DIN bar. Additional 15 Digital Inputs (DI2-DI16) 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.

DI1 AUX (mZone 12 only)Digital Inputs (DI) are opto-insulated dry contacts. DI are used to communicate the status of external devices to the mZone module.DI can be programmed to be triggered by normally open (NO) or normally close (NC) external contacts. By default a DI is preset to work with a NO contact. In case of event, an external contact is closed and acknowledged by the DI.

N (neutral), L (line) and GND (ground/earth) are the terminals to connect a power cord (not included) to the mZone.

The fuse holder and disconnect switch can also be used as a fused switch to shut off power to the device by safely extracting the fuse holder.

Both mZone 8 and mZone 12 are supplied with a 4A fuse and one spare fuse (in the fuse holder). 1 Amp is absorbed by the mZone itself and the remaining 3 Amps are available for the power relays mZone8DO8

(PWR) and mZone12DO15 (PWR). If more then 3 Amps are required, main fuse must be upgraded accordingly.

Use ceramic fuse cartridge (8.5x31.5mm).

Notes

1. Digital Outputs mZone8DO1-DO8 and mZone12DO1-DO12 are normally open 24VDC wet contacts (max 5Amps). They are used control zone valves and/or thermal actuators (24VDC). Digital Outputs mZone8DO8 and mZone12DO13-DO15 are used to control the 24VDC coils of the miniature power relays labeled mZone8DO8 (PWR) and mZone12DO13-DO15 (PWR). mZone8DO8 can only have one usage: either DO8 (24VDC) or power relay DO8 (PWR).

2. Refer to “Relay holders and power relays” in the user manual for more details.

The DO13-DO15 of the Emerson I/O controller are 24VDC wet normally open contacts connected to the coil terminals of three relays holders to provide three contacts that can be singularly wired as dry or wet contacts.

DO13 and DO14 (DRY CONTACTS) are pre-wired as dry contacts. Use the 11 as common and 14 as normally open (or 12 as normally closed).

Double pole dry contact relay 2

If a double pole relay is required, use COM 21 as common and NO 24 as normally open (or NC 22 as normally closed) for an additional pole. The two poles (11 - 14/12 and 21 - 24/22) are electrically isolated but are activated at the same time by DO13 or DO14 powering the common coil.

DO15 (PWR) is used to power a circulator pump (or other high voltage devices) with a normally open control using 14 , as neutral (N) and 24 as hot terminal (L) (or 12 as neutral (N) and 22 as hot terminal (L), for a normally closed control).

The voltage supplied by the relay DO8 (PWR) is 110VAC or 220VAC, depending on the mZone AC power, and is protected by the same fuse of the mZone 8.

Any high voltage device connected to DO15 (PWR) will be powered by the same mZone AC power supply and will be protected by the same fuse. The mZone is supplied with a 4A fuse. 1 Amp is absorbed by the mZone itself and the remaining 3 Amps are available for the power relay DO15 (PWR). If more then 3 Amps are required, the main fuse must be upgraded accordingly. Power relay is rated 250VAC/6A (max 400VAC/10A).

The DO8 of the Emerson I/O controller is a 24 VDC wet contact that is wired in parallel as ZONE THERMAL ACTUATORS DO8 and as power relay DO8 (PWR).

The mZone 8 Digital Output DO8 can be used:

• to control the thermal actuator or zone valve of the zone number 8

or, if the number of zones to control are less then 8,

• to control the DO8 (PWR) power relay to activate a circulator pump or another high voltage devices.

DO8 (PWR) is used to power a circulator pump (or other high voltage devices) with a normally open control using 14 , as neutral (N) and 24 as hot terminal (L) (or 12 as neutral (N) and 22 as hot terminal (L), for a normally closed control).

The voltage supplied by the relay DO8 (PWR) is 110VAC or 220VAC, depending on the mZone AC power, and is protected by the same fuse of the mZone 8.

Any high voltage device connected to DO8 (PWR) will be powered by the same mZone AC power supply and will be protected by the same fuse. The mZone is supplied with a 4A fuse. 1 Amp is absorbed by the mZone itself and the remaining 3 Amps are available for the power relay. If more then 3 Amps are required, the main fuse must be upgraded accordingly. Power relay is rated 250VAC/6A (max 400VAC/10A).

If you use DO8 (PWR) to control a circulator pump, only up to seven different zones can be controlled. If more then 7 zones are need, use mZone 12.

Notes

1. The AC power wires can be derived from the mZone mains or, alternatively, from the adjacent DO15 relay holder, COM 11 (N) and COM 21 (L). In this case the controlled device will be under the same fuse of the mZone. Fuse might be upgraded based on the controlled device load.


Rewiring mZone12DO13-DO14 from dry contacts to high voltage (110/220VAC) wet contacts

mZone 12 features two auxiliary digital outputs (DO13 and DO14) for general purpose that are pre-wired a on two relays holders as dry contacts. To use these two contacts, a miniature relay is required (Finder relay model 44.52.9.024, not included).

One or both dry contacts (DO13 and/or DO14) can be wired as high voltage (110/220VAC) wet contact/s following the instructions below.


High voltage (110/220VAC) wet contacts(Additional AC power)

Connect an additional AC power circuit to the COM 11 (N) and COM 21 (L ) on the DO13/DO14 relay holder/s, as shown on the electric schematic above 1.

And additional AC power with a dedicated circuit breaker must be added.

To control a 110/220VAC 1 device use the terminals:

14 (N) and 24 (L)or

12 (N) and 22 (L)

for a normally open contact for a normally closed contact.

Notes

1. 110VAC or 208VAC or 220VAC or 230VAC (50 or 60Hz) depending on the mZone AC power.

Disconnect the neutral (N) and line (L) wires connected to the relay holder on terminals COM 11 (0VAC) and COM 21 (110/220VAC 1).

Cover the exposed neutral (N) and line (L) wires with twist-on connectors and tape over the wire nut for extra assurance.

Use the COM 11 as common and NO 14 as normally open or NC 12 as normally closed dry contact. Alternatively, or in addition, use the COM 21 as common and NO 24 as normally open or NC 22 as normally closed dry contact.

The two dry contacts ( 11 - 14 / 12 and 21 - 24 / 22 ) are electrically isolated but activated at the same time by mZone8DO8 or mZone12DO15.

To activate these contacts, insert a Finder mini relay model 44.52.9.024 (not included) in the relay holder and pull-up the holding band.

Rewiring mZone8DO8 and mZone12DO15 from 110/220VAC 1 wet contacts to dry contacts

mZone module features one digital output (DO8 for mZone 8 and DO15 for mZone 12) wired as normally open 110/220VAC 1 wet contacts dedicated to directly activate a circulator pump or other high voltage devices. The circulator pump connected to the wet contacts NO 14 (N) and NO 24 (L) will be turned on and off by the relay based on the status of its related digital output (mZone8DO8 and mZone12DO15).

In case the circulator pump or another device need to be controlled with an on/off potential-free contact or a 24VDC contact, the mZone8DO8 or mZone12DO15 digital output must be re-wired accordingly.Follow the instructions below to rewire the two wet 110/220VAC 1 contacts into dry contacts.

Before proceeding disconnect power. When completed, mark off the “PWR N | L” text on the label to avoid future errors.
