ISU SERIES – UNDERCEILING OR CONSOLE SPLIT SYSTEM AIR CONDITIONERS
GENERAL
ISU – Indoor Unit.
OSA ✳RK – Outdoor unit, reverse cycle.
Quiet
The carefully designed fans ensure the ISU
units' emit minimal noise, while maintaining
the efficiency of the unit.
Application
Typically installed in office areas, shops,
restaurants, night clubs and other commercial
and public spaces where unobtrusive air
conditioning is required.
The Outdoor Unit is also very quiet with
a compressor/motor within a hermetically
sealed casing which in turn is mounted in an
acoustically insulated compartment.
Underceiling units are ideal for rooms with
limited or no ceiling space. Sloping ceilings
are not a problem as the units can still be
suspended level.
Circulates
The air discharge louvre is motorised to
distribute conditioned air high and low into
the room. If preferred, however, the motor
can be switched off and the louvre can be set
at a fixed angle. Left and right air distribution
is manually set to suit.
ISU/OSA systems are available for reverse
cycle (heat piump) applications.
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. Design
The slimline low profile styling allows the
Indoor Unit to be suspended unobtrusively
under the ceiling, where it does not
use valuable office wall or floor space.
Alternatively, if it is more convenient the unit
can be mounted vertically as a console, e.g. under a window.
Accessible
The filter is easily accessible for periodic
cleaning via the indoor unit's hinge down/
removable return air filter panel.
Durable Outdoor Unit
The Outdoor Unit is built to withstand the
rigours of the weather, year in and year out.
The cabinet is made from the high quality
galvanised steel, finished with tough ovencured polyester powder coating and fixed
with stainless steel fasteners. The outdoor
coil fins are epoxy coated for extra protection
in corrosive environments, e.g. salt laden
sea air.
Refrigerant R410A
Each complete system uses refrigerant
R410A which is deemed to have zero ozone
depletion potential.
Efficient
These reverse cycle (heat pump) systems
are very efficient. For every 1 kW of power
consumed approx. 3 kW of heating is
created. The outdoor unit incorporates a high
efficiency scroll compressor. Heat exchange
coils incorporate inner grooved (rifled) tube
for better heat transfer.
Self Diagnostics
The Outdoor Unit's Controller (OUC) has a
display of LEDs to indicate faults and running conditions. A general fault indicator is
included for interface to external systems.
OPTIONAL ACCESSORIES
Outdoor Unit:
1. Fault indicating auxillary relay board.
2. Wall mounting brackets.
Technical Backup
Manufacturer's representation assures
quality technical backup, quick and efficient
parts and service.
The manufacturer operates a quality
management system that conforms to AS/NZS ISO 9001:2000.
SAT-2 CONTROLLER
The Outdoor Unit is designed to be
freestanding, or wall mounted with the
optional wall mounting brackets.
Features
• Cool / Dry / Fan modes.
• Heat / Auto modes
• Auto / High / Medium / Low fan speed
selection.
• Temperature setting range from 16°C
– 30°C.
• LED to indicate status of the unit
[Power On/Off].
• Room temperature display.
• Real time clock.
• 7 day timer – two start and/or stops per day
• On demand countdown run timer, up to 9 hours.
User Friendly
ISU unit's are supplied with a SAT-2
Controller. This thermostat has been
designed to maintain a high level of comfort
for room occupants. Emphasis has been
placed on providing controls that are
easy to use — despite the sophisticated
microprocessor system that runs it. Use of
the Auto and Timer function settings allows
you to 'set it and forget it'.
• Auto-Restart or No Restart after power
failure.
• Continuous or Intermittent selection of
fan run-on in dead zone.
• Backlit screen for ease of reading; changes
colour for each mode.
• Soft touch tab keys
• Battery backup (Lithium).
• Sleep function.
• Audible beep to acknowledge key entry or
wireless remote control.
• Low voltage control cable.
• Colour: white and light grey (Keypad - gold
and blue).
• Optional: Infra Red Remote controller
Remote return air sensor, Extended interface lead, Extra Wall Control plaque.
