Start-Up Benefits; Automatic Start-Up Test - Hitachi UTOPIA R32 Series Technical Catalogue

2 Features and benefits
Start-up benefits
No need for remote control relay wiring in UTOPIA Prime
In the case of UTOPIA Prime systems comprising several
indoor units (up to 4 indoor units), indoor units can be
controlled from a single remote controller, without the need
to link them up with dedicated remote control relay wiring.
A: Service cable.
B: Dedicated cable for remote control relay, not required
when units are set to simultaneous operation.
The indoor units must be H-LINK II-compatible models.

2.6 Start-up benefits

2.6.1 Automatic start-up test

The installation is started up automatically, therefore considerably reducing the time required for the process.
There are the following types of start-up:
• Test run and identification of the units forming the system.
• Test run from the remote control.
• Test run from the outdoor unit.

Test run and identification of the system units
The test run can be carried out from either the rotating DIP switches on the outdoor unit or from the remote control for the
indoor unit.
The seven-segment indicator on the outdoor unit provides all of the
information required to check the system is operating properly.
The units forming part of the system are identified separately for the
outdoor and indoor units:
• Outdoor units: the remote control can be use to allocate the
series to which the operational outdoor units belong (e.g. single or
multiple series).
• Indoor units: using the rotating DIP switch on each unit.

Test run from the remote control
Three operations for the test run are possible from the remote control:
1 Auto-diagnostic: quick check of the operating conditions of the
indoor units and outdoor unit.
2 Data memory query: in the event of an alarm, the remote control
saves all the operating parameters of the unit at that particular
time and the screen displays the corresponding fault code. The air
conditioning system diagnostic is simple and effective.
3 Optional function setting: the remote control is able to make
settings on up to 29 possible options, such as the four-degree
offset in heating mode or the increase in fan speed. It is possible
to set several indoor units at the same time and to modify the unit
configuration once installation is complete.

Test run from the outdoor unit
The seven-segment indicator on the outdoor unit displays parameters relating to its working order.
Any incident arising during start-up or normal operation can be diagnosed from the indicator.
