DISPLAY CONNECTION TO CONTROL MULTIPLE UNITS 

 

 

The EQA649 / EQB649 or ERA649 / 

ERB649 panel provides for the control of 

several units; it is possible to connect 

up to 30 units which will be managed by 

a single remote panel; 
They must be connected in series with 

an in and out connection on the boards 

of the individual units; 
The network is an RS485 network; Use a 

2-wire shielded cable with a maximum 

length of 150 m; 
 
- Carry out a layout in order to minimize 

the length of the leads; 
- terminate the line with the supplied 

120 

Ω

 resistor;   

- do not make "star" connections;   
- the connection with the RS485 cable is 

polarized,

 

 

 

 

REMOTE ON OFF CONNECTION   

 

 
 
The EQA649 / EQB649 or ERA649 / 

ERB649 remote panel provides an ON 

OFF command with which the unit can 

be connected through a clean contact to 

a device for remote switching on / off 

the unit such as a switch or a timer   
 
The logic provides:
