Extended design operation conditions

Cooling design operation conditions: The cooling operation range has been extended to -10°C ~ 52°C by changing the outdoor fan to an Inverter type.
Heating design operation conditions: Stable heating operation even with an outside air temperature of -20°C. The heating operation range has been extended to -20°C by use of a compressor with a high-pressure vessel.

Wide temperature setting range
Wired remote control heating temperature setting range is 16 to 30°C.

Power suppression control for energy saving (Demand control) 1)

The 3-Pipe ECOi EX MF3 Series has a built-in demand function which uses the inverter characteristics. With this demand function, the power consumption can be set in three steps, and operation 2) at optimum performance is performed according to the setting and the power consumption. This function is useful to reduce the annual power consumption and to save electricity costs while maintaining comfort.

1) An outdoor Seri-Para I/O unit is required for demand input.
2) Setting is possible as 0% or in the range from 40 to 100% (in steps of 5%). At the time of shipping, setting has been done to the three steps of 0%, 70%, and 100%.

Slim 3-Pipe Control Box Kit / Multiple connection type

Heat Recovery Box to connect multiple indoor units with just one box, 4, 6 and up to 8 indoor units or groups.
The height is only 200mm. This is good advantage specially in hotel applications, where space for connecting several boxes is limited.

Individual control of multiple indoor units with solenoid valve kits.
· Any design and layout can be used in a single system.
· Cooling operation is possible up to an outdoor temperature of -10°C.

3-Pipe ECOi EX MF3 Series Superior Flexibility

Increased piping lengths and design flexibility

Adaptable to various building types and sizes. Actual piping length: 200m. Maximum piping length: 500m.

  1. Maximum height difference between outdoor unit and indoor unit: 50m * (Max 90m) 2)
  2.  Maximum height difference between indoor units: 15m (Max 30m) **
  3. Farthest pipe length (from outdoor unit to farthest indoor unit) (equivalent length): 200m
  4. Maximum total pipe length: 500m
* 40m if the outdoor unit is below the indoor unit.
** Setting change is necessary. Please contact an authorized Panasonic dealer in the case of conditions below:
50 < Height difference between OU and IU ≤ 90 or 15 < Height difference between IUs ≤ 30.

Up to 40m piping after first branch

Up to 52 units can be connected to one system. Flexible piping layout makes it easier to design systems for locations such as train stations, airports, schools and hospitals.

Excellent cost saving and smaller piping size

By using R410A with low pressure loss, pipe sizes for discharge, suction and liquid are all reduced.
This makes it possible to aim for reduced piping space, improved workability at the site, and reduction of the piping material costs.

High external static pressure on condensers

With a newly designed fan, fan guard, motor, and casing, new models can be custom-installed on-site to provide up to 80 Pa of external static pressure.
An air discharge duct prevents shortages of air circulation, allowing outdoor units to be installed on every floor of a building.
