4-3-1 (7) Setup of relay connector and terminator
• After trial operation for each refrigerant system, set the relay connector and terminator resistor for all
refrigerant system which are connected from one TCS-NET relay interface.
<Procedure>
1
How to set up terminator resistor (SW30)
When all the address setups have finished in the same
refrigerant system, put the terminator resistor (SW30) in the
same central control line into one.
• Remain only SW30-2 of the header outdoor unit with the
least line address number as it is ON.
(With terminal resistor)
• Set up SW30-2 of the other header outdoor units to OFF.
(Without terminal resistor)
2
Connect the relay connector between [U1U2] and
[U3U4] of the header outdoor unit for each refrigerant
system.
