Setting the Indoor units
4
Before starting the redundancy controller please confirm following has been carried out:
• Each system has been completely started up: pressure test, evacuation, refrigerant filling, powering up,
addressing and test run had been finished successfully. Please do not proceed before start up has been
performed and good operation verified on each system.
• Each system is equipped with a remote controller (it can be any local or centralized controller which is
suitable for that model).
1.
Please cut the jumper JP001 on each indoor unit main PCB. (See Fig. 4-1.)
This will convert T10 signals to static ones.
2.
Set the 2 (or 3) indoor units (or groups) to the desired mode and temperature. Take care that it must be
the same mode for all, in order to get the redundancy function and not make the units to work against
each other.
