1. Quick start guide Step 1: Mount the Procon MelcoREMOTE and power supply on suitable DIN rail and complete the wiring between the two. Connect the 230VAC power supply but do not switch ON. Step 2: Connect the GPRS antenna or Ethernet cable, depending on the desired server connection method.
- Contact may result in electric shock, fire or smoke • Do not reconstruct or change the settings of the protection devices - If the protection device is shorted or operated forcibly, or parts other than those specified by Mitsubishi Electric are used, fire or explosion may result •...
Internet, allowing users to monitor and control A/C and other devices from anywhere in the world by simply logging onto a webpage or by using a smartphone app. Procon MelcoREMOTE connects to the Internet and communicates with a central server, uploading stored data logs and downloading configuration data.
4. Mounting The MelcoREMOTE and power supply should be mounted on DIN rail in a panel of suitable size, leaving enough space around the unit for cable conduit and additional equipment. 4.1. Power supply dimensions 93mm 56mm 76mm 4.2. MelcoREMOTE dimensions...
4.3. Mounting flanges Appropriate wall fixings must be used 4.4. Installation Location When installing MelcoREMOTE: Avoid locations in direct sunlight Avoid locations exposed to steam or oil vapour Avoid locations where combustible gas may leak, settle or be generated Avoid installation near machines emitting high-frequency waves...
To maintain the appropriate EMC classification for the intended environment the Ferrite Core supplied with the MelcoREMOTE must be installed onto the antenna cable with 2 loops (Image below), and be located at the boundary of the panel the MelcoREMOTE is installed within.
If communication via Ethernet is required then in order to maintain the appropriate EMC classification for the intended environment a cable ferrite (Wurth 74271221S) must be Installed onto the CAT 5/6 cable with 1 loop (Image below), and be located as close as possible to the MelcoREMOTE Ethernet socket. Page 14 of 52...
A double pole (Live and Neutral) 5A switch or circuit breaker must be provided in line with the supply to the MelcoREMOTE power supply and be in close proximity to it. It must be clearly marked as the disconnecting device for the MelcoREMOTE.
8. Connecting I/O Caution: Only use shielded cables for connecting sensors to MelcoREMOTE, to reduce the possibility of interference with radio communications services. Using shielded cables ensures that you maintain the appropriate EMC classification for the intended environment. All shields must be tied to an appropriate Earth point within the installation panel.
To connect a 4-20mA sensor that requires “loop” power: Isolate the MelcoREMOTE supply. Connect the positive (+) terminal on the sensor to the RS-485 Port 1+ or RS-485 Port 2+ terminal on the MelcoREMOTE. Connect the negative (-) terminal on the sensor to the required positive (+) configurable input terminal on MelcoREMOTE (e.g.
Return Air Temperature can be monitored. 9.1. Connection using crossover cable If a single centralised controller is to be connected to the MelcoREMOTE then a direct connection between the two can be made using a crossover cable.
The default IP address for MelcoREMOTE is 192.168.1.2 and subnet mask 255.255.255.0. When connecting Ethernet devices together each one needs to have a unique IP address. 9.3.1. PIN Codes The following PIN codes must be entered to enable communication between the central controller and MelcoREMOTE. Controller Type PIN Code required...
Connecting Modbus Devices MelcoREMOTE can act as a Modbus Master device and be configured to communicate with external Modbus Slave devices, to expand its I/O. The following types of Modbus Slave device can be connected to MelcoREMOTE : Devices supporting the Modbus RTU protocol via RS-485 (e.g. MelcoBEMS MINI (A1M)) Devices supporting the Modbus TCP protocol via Ethernet 10.1.
(See the Technical specification section for more information). If an external power source is used to power the device, ensure that MelcoREMOTE and the device have a shared ground connection (the RS-485 - terminal can be used for this).
11.1. GPRS An active GPRS enabled SIM card needs to be fitted inside the MelcoREMOTE unit to provide a server connection via GPRS. In addition the supplied GPRS antenna must be fitted and screwed firmly into the unit. 11.1.1. Fitting/Replacing a SIM Card Under certain circumstances it may be necessary to fit or change the SIM card in the MelcoREMOTE unit.
Replace the lid of the unit by pressing down until it has clicked into place. It may be necessary to change the MelcoREMOTE network setting after the new SIM is fitted. See the Configuration and Commissioning chapter for more information on how to do this.
Ethernet can be used to connect to the server as an alternative to GPRS. MelcoREMOTE has a 10BASE-T Ethernet controller built in to allow the unit to connect to the server via a corporate Ethernet network, using standard Cat5/Cat6 cable.
Upon applying power the MelcoREMOTE will beep twice and the LCD backlight will illuminate. After a few seconds the MelcoREMOTE firmware version will be briefly shown before the Status Screen. MelcoREMOTE will immediately attempt to connect and synchronise with the server via GPRS or Ethernet.
When using GPRS the current GSM signal strength will be shown in addition to server connection information, when using Ethernet the IP address of the MelcoREMOTE will be shown, when set to be an I/O module the Modbus RTU Slave ID and Baud Rate will be shown.
When set to GPRS or Ethernet the text in the centre of the screen describes the current connection state. This text will change whilst the MelcoREMOTE establishes a server connection. The sequence of events MelcoREMOTE would typically take to synchronise with the server (using GPRS) are:...
The I/O Status and Configuration screens can be protected by means of an optional 4-digit Commissioning Password. When shipped from the factory MelcoREMOTE does not have this password enabled and all screens are freely accessible. After commissioning this password can be enabled and changed to prevent unauthorised access to MelcoREMOTE configuration and output overrides.
12.6. Configuration screen From the Status screen the Configuration screen can be accessed. The Configuration screen allows the connection settings to be modified. The Up and Down buttons can be used to change the value currently shown, the Select button can be used to move onto the next highlighted field, if applicable (e.g.
SIM will be supplied activated and roaming from Ex-Works Date, this will be the beginning of the 60 month SIM Contract. See Server Connection chapter for more details on using SIM cards in MelcoREMOTE SIM network selection screen 12.6.2. I/O Types When set to standalone I/O module mode (Connection Type set to None (slave)) the configurable input types can be changed via the Configuration Screen.
12.7. I/O Status screen The I/O Status screen shows live values for all MelcoREMOTE I/Os (for Variable type I/Os only the ones being logged are shown). When the I/O Status screen is first entered it shows the name and live value for input IN01. The value will update every second.
External device I/Os are only viewable on the screen if those external devices have been pre-configured. If MelcoREMOTE fails to read a register from an external device its value will show READ ERROR, or if MelcoREMOTE fails to write to a register value WRITE ERROR will be shown.
The output will remain in the overridden state until either the Back, Up or Down buttons are pressed. At this point the output will resume its previous state from before the Toggle button was pressed the first time for that output. Any control logic set up to control the output will resume.

Modbus Slave Register tables All MelcoREMOTE I/Os are exposed as both Modbus Input (analogue input) registers and Modbus Holding (analogue output) registers. The register numbers are the same for both register types. Each I/O value is exposed as a 32-bit value, so two Modbus registers are used for each I/O value. The lower of the two register numbers holds the most significant 16-bits of the I/O value.
