5. Installation 5.1. Physical connection The MelCOMMS MINI has four screw holes on the base plate of the panel. These can be used to attach the unit in place. Please secure the MelCOMMS MINI before powering the unit on. 5.2. Power supply A double pole (Live and Neutral) 5A switch or circuit breaker must be provided in line with the supply to the MelCOMMS MINI power supply and be in close proximity to it. -
Page 15: Configuration
The configuration is done using the 12x DIP switches, 4x digital inputs and 4x configurable inputs (which are fixed as digital inputs). To help installers who are already familiar with the PANEL_RS product the 4x digital inputs on the MelCOMMS MINI will be used as follows:... - Page 16 DIP Switch Usage Number of units connected [1-1 | 1-2 | 1-3] Number of units running [1-4 | 1-5 | 1-6] Days between rotation [1-7 | 1-8] = 1 day = 3 days = 5 days = 7 days Temperature setpoint (ºC) [2-1 | 2-2 | 2-3] = 18ºC = 19ºC...

A communication fault between MelCOMMS MINI and one or more MelcoBEMS MINI (A1M) units. A fault code read from any MelcoBEMS MINI (A1M) unit which is not 8000 (8000 = OK). -
Page 18: Rs-485 Comms Status Led
5.6.4. RS-485 Comms Status LED Next to the DIP switches are two LEDs, one of these will constantly be ON and the other will flash to indicate successful Modbus communication with the MelcoBEMS MINI (A1M) units. If both are permanently ON then this indicates no communication with the MelcoBEMS MINI (A1M) units. -
Page 19: Control Functionality
6. Control Functionality 6.1. Automatic Mode When the switch on the front panel is set to ‘Automatic’ the MelCOMMS MINI will perform Backup & Rotate functionality. 6.1.1. Backup & Rotate A common installation scenario is a number of split systems that operate on a cyclical basis, with one unit on backup to operate in case of failure. -
Page 20: Manual Mode
6.4. Modbus Slave Test Mode MelCOMMS MINI can be put into Modbus slave test mode by powering the unit up with the 8 DIP switches 1-1 to 1-8 all in the OFF position. In this mode the MelCOMMS MINI unit will not attempt to communicate with any MelcoBEMS MINI (A1M) devices, the RS-485 port will instead be used to provide Modbus RTU Slave functionality. - Page 21 Input Status Registers (Digital Inputs) Modicon Register Name Address Details Address Digital Input 1 state 10001 Digital Input 2 state 10002 Digital Input 3 state 10003 0 = Input open circuit (no wire link present) Digital Input 4 state 10004 1 = Input closed circuit (wire link present) Input IN01 state 10005...
