ISD 380–950 Series
Applications
These units have been specifically developed for air conditioning of commercial premises, e.g. offices, motels, shops and restaurants
AIR FLOW SELECTION
If the air returning to the indoor coil is regularly expected to be above
50%RH, then the coil face velocity should be limited to be
2.5 m/s or less.
High humidity levels can occur in tropical or subtropical conditions,
and/or when heavily moisture laden fresh air is introduced.
FEATURES
Refrigerant R410A
Each complete system uses refrigerant
R410A which has a zero ozone depletion
potential.
Economical
These ISD/OSA systems have two
independent refrigeration circuits to provide
the flexibility and economy of two stage
operation, i.e. utilising one or two circuits as
conditions vary, plus the advantage of
staggered starting.
Efficient
Each outdoor unit incorporates a high
efficiency scroll compressor. ISD 380 indoor
units include high efficiency EC motors.
Heat exchange coils incorporate inner
grooved (rifled) tube for better heat transfer.
Quiet
ISD 380 models: Each integral high
efficiency electronically commutated (EC)
motor can vary from zero to full speed. This
allows slow ramp up with no sudden noise
change. The motor can be controlled to
have the best air flow for the ducting and
requirements as well as used for
de-humidifying the space.
Outdoor noise is a function of how hard the unit
needs to work. When the outdoor unit is not
running at maximum capacity in mid- season
the outdoor fan speed and noise reduces.
The compressor is isolated in a built-in, insulated
compartment to minimise noise. The indoor unit
is also insulated for noise attenuation.
Performance
Use of forward curved fan enables fine
tuning of the indoor unit to match the supply
air requirements.
ISD 380KB-P models: Use of backward
curved plug fan enables fine tuning of the
indoor unit to match higher static pressure
supply air requirements.
EC motor fans have a fully integrated speed
control that enables soft starting. Fan speed
can be stepped to your own requirements
or continuously variable using a 0–10V DC
control signal.
The system includes a temperature sensing
head pressure control which enables the
system to compensate for outdoor ambient
temperatures below 20°C on cooling cycle,
and above 15°C on heating cycle.
Consideration must always be given to selecting an air flow and face
velocity that avoids water carry-over problems.
Applications using full or high proportions of fresh air should be
referred to your nearest temperzone sales office to establish the
correct selection of units.
Durable
The indoor and outdoor coil fins are epoxy
coated for extra protection in corrosive
environments, e.g. salt laden sea air. The
outdoor unit’s cabinet is constructed from
high grade galvanised steel - polyester
powder coated (grey) for all weather
protection (IP 44). External fasteners are
stainless steel. Heat exchange coils
comprise aluminium plate fins on
mechanically expanded rifled copper tube.
Coil protection guards are supplied. The
indoor unit’s cabinet is constructed from
high grade galvanised steel and also includes
a polyester powder coated drain tray.
Low Maintenance
EC motor models* - commissioning and
maintenance costs are reduced through use
of a fan that requires no pulley and belt
adjustments or changes like traditional fans.
Page 4
ISD 380–950 Series
Soft Starting
EC motor models* - EC motors are soft
starting therefore have none of the
problems associated with high in rush
current.
Control Option
EC motor models* - Fixed and stable air
flows can be achieved through use of a
differential pressure transducer and
controller (supplied by others) to
compensate for varying duct static
pressures caused by dirty filters or
modulating dampers. Commissioning is also
made easier. The system is set up for the EC
motor to be controlled variably by a 0–10
volt DC signal that can be supplied either by
a BMS system, a sophisticated controller or
temperzone’s optional TZT-100 Controller;
the optional Signal Isolator will be required in
this instance for ISD 380KBY models.
Systems’ using UC6 controller* are BMS
compatible with multi-unit control possible
– either via digital and analogue signals or via
Modbus. Refer to temperzone for protocols
available.
Insulation
Closed cell foam insulation has been used in
the indoor unit ’s cabinet to ensure no
particles are introduced into the air stream.
The insulation is foil faced and meets fire
test standards AS 1530.3 (1999) and BS 476
parts 6 & 7.
OPTIONAL EQUIPMENT
Outdoor Unit:
UC6 Service Interface tool (OSA 310–670 only)
Indoor Unit:
1. Vertical supply air configuration.
2. Filters - EU4/G4 rated.
3. temperzone TZT-100 Room T/stat, or SAT-2 (24V) Controller kit
(for non-digitals).
4. Signal isolator (Item no. 201-000-129) for using EC motors
in a 0–10V DC continuously variable speed mode on
ISD 380KBY models.
SAFETY FEATURES
1. HP and loss of refrigerant protection.
2. Anti-rapid cycle timer and internal overload for compressor
protection.
3. Circuit breaker control circuits.
4. Time-and-temperature controlled electronic de-ice switch
prevents icing up of the outdoor coil during heating cycle.
5. Frost protection on cooling cycle.
6. Sensor fault indication.
7. Compressor minimum run time to ensure oil return.
8. Crankcase heater prevents liquid refrigerant condensing in the
compressors during the 'off' cycle.
9. Phase rotation protection device.
10. 24V control circuit
Self Diagnostics
Systems that includes a controller (UC6)
have a 7 segment LED display to indicate
faults and running conditions. Many
operating status conditions (including
history) can be determined, without gauges,
simply by using the optional UC6 Service
Interface graphical display tool.
Note: OSA 870/950 use OUC4 controller.

Refer Specification tables ( p.19/20) to identif y
applicable models
COMPRESSOR
Each high efficiency scroll type compressor is hermetically sealed,
quiet running and supported on rubber mounts to minimise
vibration.
REFRIGERATION PIPING
The standard unit allows for a line length up to 60 m or more ; refer
specifications table pages 19 & 20.
Max. height separations between units are:
Outdoor unit above indoor unit: 20m
Outdoor unit below indoor unit: 20m.
Each OSA is shipped from the factory with a charge of R410A
refrigerant sufficient for a 10m line length. Liquid and suction service
valves are provided. Accurator expansion devices control the flow of
refrigerant. The matched indoor unit is shipped with a holding charge
of nitrogen. Both units have brazed pipe connections.
WIRING
The electrical supply required is:
3 phase 380 –415 V a.c. 50 Hz with neutral and earth.
The compressor crankcase heater requires a 24 hour power supply.
A control panel, located in each outdoor unit, is fully wired ready to
accept the main power supply. Each system complies with the
requirements of the Regulatory Compliance Mark (RCM) for
electrical safety (AS/NZS 60335.2.40) and EMC (AS/NZS CISPR.14).

Plug Fan Advantages
The ISD 380/570/670 KB-P models with EC motor and backward
curved plug fan design have the following advantages:
- higher static pressure performance (refer page 4)
- quieter than conventional fan (refer page 3); a large aperture
supply air spigot reduces exit velocities and therefore less noise
down ductwork. Each EC motor can vary from zero to full speed.
This allows slow ramp up with no sudden noise change.
- lower installation cost due to a large supply air spigot which
lessens the need for duct transitions.
- EC motors are soft starting therefore have none of the problems
associated with high in-rush current.
- commissioning and maintenance costs are reduced through
use of a fan that requires no pulley and belt adjustments or
changes like traditional fans.
- fixed and stable air flows can be achieved through use of a
differential pressure transducer and controller (supplied by
others) to compensate for varying duct static pressures caused
by dirty filters or modulating dampers. Commissioning is also
made easier.
Digital Version
Digital Scroll Compressor
A digital version of the some outdoor units (OSA 380) is available
that includes one fixed and one digital compressor. This provides
an enhanced variable capacity ability that enables closer control
of room temperature. Digital compressors have proven very
reliable because of their design simplicity. Electrical harmonic
noise is very low.
Extended Capability
Digitals are particularly suitable for applications requiring full or
high proportions of fresh air, VAV, close control and supply air
temperature control.
- the system is set up for the EC motor to be controlled variably by
a 0–10 volt DC signal that can be supplied either by a BMS
system, a sophisticated controller or temperzone's optional
TZT-100 Controller.
- significant power savings are possible by slowing the fan during
low occupancy or after hours (75% airflow ≈ 55% power use).
