DESCRIPTION
The Multi Zone Series are ductless climate systems. They are designed
with a matching indoor unit for optimum performance and efficiency.
These climate systems are supported with accessories and documents
to serve specific functions.
FEATURES
Variable Frequency Rotary Compressor - Twin rotary inverter compressor
on all models features high efficiency operation that modulates down to 15
Hz and as high as 120 Hz for reduced vibration and quiet operation. Brush-
less DC motor uses powerful Neodymium magnets that are approximately
15-20 times stronger than ferrite magnets used in conventional AC compres-
sors. The DC Inverter Control provides continuous operation, while adjusting
capacity according to room temperature. The accurate sensing of cooling or
heating loads prevents frequent changes in capacity and ensures efficient,
economical operation.
Low Ambient Cooling Operation Down to 5 °F - This feature allows for a
space to be air-conditioned even in outdoor temperatures as low as 5 °F.
This cooling ability is important when dealing with server equipment rooms,
surveillance mechanical rooms, restaurant kitchens, fitness centers, and
more.
Condenser High Temperature Protection - The outdoor coil thermistor
continuously monitors the temperature and communicates with the micro-
processor. Depending on the temperature measured, the compressor will be
allowed to increase the frequency if needed to meet the load or is forced to
run at the current or reduced frequency. If the temperature gets excessively
high the compressor will be de-energized.
High Pressure Discharge Temperature - The compressor discharge line
thermistor continuously monitors the temperature and communicates with
the microprocessor. Depending on the temperature measured, the compres-
sor will be allowed to increase the frequency to meet the load or is forced to
run at the current or reduced frequency. If the temperature gets excessively
high, the compressor will be de-energized.
Defrost Control (Heat Pump Models) - Defrost cycle is automatically
enabled if there is a build-up of frost on the outdoor coil. Outdoor fan and
indoor blower operation is terminated during the defrost cycle. H1 is dis-
played on the indoor unit panel on the front cover during a defrost cycle.
Reversing Valve (Heat Pump Models) - 4-way interchange reversing valve
effects a rapid change in direction of refrigerant flow resulting in quick
changeover from cooling to heating and vice versa. Valve operates on sys-
tem pressure differential between outdoor unit and indoor unit.
R-410A Refrigerant - Unit is pre-charged with R410A refrigerant that uses
PVE refrigerant oil. Polyvinylether (PVE) is an innovative refrigerant oil spe-
cially formulated for hydrofluorocarbon (HFC) refrigeration systems. In addi-
tion to providing lubricating properties, it also has a number of other applied
advantages that help to increase the reliability of the refrigeration systems
where it is applied.
Refrigerant Line Connections, Service Valve - Outdoor units are
designed with easy service and maintenance in mind. Maintenance points
are located behind easy-access panels, to make installation and service a
breeze for a trained technician. Flare connection lines are located on side of
unit cabinet. Fully serviceable brass service valve prevents corrosion and
provide access to refrigerant system. Shut-off valve that can be fully shut off
while 2-way service valve (with service port) may be front seated to manage
refrigerant charge while servicing system.
Air Deflection Louvers - Horizontal louvers default to the cooling or heating
position when the unit is operating. Horizontal louvers can be set to a preset
oscillating range or fixed position from the wireless remote control. Full oscil-
lating is the default setting when button is pushed. Vertical louvers can be
manually adjusted to direct the airflow for optimal comfort.
Indoor Coil Freeze Protection - The indoor coil thermistor monitors the coil
temperature continuously. Any time the coil temperature drops below 30°F,
the compressor and the outdoor fan (30 seconds later) will be switched off
until the coil temperature rises above 43°F and the compressor has been off
for a minimum of 3 minutes.
I FEEL Function - When I FEEL is activated, the system will satisfy your
cooling or heating temperature setpoint where the remote control is located.
When I FEEL is deactivated, the system will satisfy the cooling or heating
temperature setpoint where the indoor unit is located. This feature provides
homeowners with optimum comfort whether they are near or far from the
indoor unit.
Hot Heat Pump (cold air prevention) - In heating mode, the indoor fan will
be delayed from 1 to 3 minutes to allow refrigerant to warm up and avoid
cold blow. This may occur during:
• Initial start-up of a heating cycle
• Immediately after completion of an Auto mode operation
Heating under extremely low indoor temperatures
