■ SYSTEM OUTLINE
1 Terminology
System related terms (♦ is for VRF system)
(a) VRF system ♦:
VRF (Variable Refrigerant Flow) is a large multi-split
system that eff ectively air conditions a wide variety of
spaces from large buildings to personal residences.
(b) Other system:
Multi-split or single-split type air conditioning system
other than VRF system.
(c) Heat recovery system ♦:
The indoor unit connects to the outdoor unit via an RB
unit in this system. RB units of single type and 4-sys-
tem multi type are available. When a certain RB Group
indoor units is performing cooling operation, other RB
Group indoor units can perform heating operation.
Please refer to (e) for RB Group. An indoor unit con-
nected to an outdoor unit without going through an RB
unit are for cooling only.
(d) Heat pump system:
This is standard system. In this system, the indoor units
can not perform the cooling operation and the heating
operation at the same time.
(e) RB Group [for heat recovery system] ♦:
A group of indoor units connected to a single type RB
unit or each system of a multi type RB unit. In the RB
Group, the indoor units can not perform cooling opera-
tion and heating operation at the same time.
(f)
R.C. Group (Remote Controller Group):
This forms a group by connecting indoor units by remote
controller cable. One indoor unit which is ungrouped is
an R.C. Group, too. It is the minimum unit of operation.
(g) Refrigeration system:
This is a system composed of indoor units and outdoor
units connected by the same refrigerant piping.
(h) System ♦:
This is 1 or 2 or more refrigerant systems connected by
the same transmission cable.
(i)
Central controller ♦:
A central remote controller can control multiple R.C.
Groups. There is a system controller, Touch panel con-
troller, and a central remote controller.
(j)
Standard remote controller:
A standard remote controller can control 1 R.C. Group
only. This unit corresponds to this. This unit cannot be
used together with a 3-wire remote controller. A wireless
remote controller can be used together with this unit.
(k) Custom Auto:
Set both the cooling and heating temperatures. Dur-
ing the Custom Auto mode operation, when the room
temperature exceeds the set temperature for cooling,
the cooling operation is performed, and when the room
temperature falls below the set temperature for heating,
the heating operation is performed. (It can be used only
when the setting of the indoor unit compatible with this
function is valid.)
(l)
Deadband:
The deadband is the minimum value of the diff erence
between the set temperature for cooling and the set
temperature for heating (= cooling set temperature -
heating set temperature) in Custom Auto mode. The
diff erence between the set temperature for cooling and
heating in Custom Auto mode can not be smaller than
the deadband. The deadband is set in the indoor unit. To
change this, consult an authorized service personnel.
