OmniCore Pro Multi Room Heat Pump Systems — Large Residential & Light Commercial

While a standard heat pump system consists of a single indoor and outdoor unit, an OmniCore Pro Heat Pump System provides heating or cooling in multiple rooms by connecting up to 8 indoor units to a single OmniCore outdoor unit.

Not only is tailoring the indoor units to each space possible to meet design requirements, less exterior space is needed by reducing the number of outdoor units — this is of particular benefit to large residential homes and commercial projects where installation space outdoors can be limited, rooftops subject to bearing loads and where exterior aesthetics matter.

An OmniCore Pro Multi Room System offers flexible install options, with over 70 different indoor units to choose from including high walls, floor consoles, ducted, in-ceiling and ceiling concealed units.

There are multiple outdoor units available depending on the scale of the project and future needs.

Key Features
  • Keep the exterior clutter-free with just one OmniCore outdoor unit
  • Connect 2 to 8 indoor units with the OmniCore Pro Mini-VRF (R410A)
  • The OmniCore Pro features over 70 indoor units to choose from

  • Guaranteed heating operation down to -20°C
  • Individual temperature control for each room
  • Built-in or Optional Wi-Fi Control available across all indoor units

Scope of Use

A Mitsubishi Electric OmniCore Multi Room Heat Pump System offers the flexibility to choose the perfect heat pump for each room with just one OmniCore outdoor unit. Intended to minimise the clutter of having several outdoor units outside while also offering flexible design opportunities and individual room temperature control — it's an ideal solution for larger homes, offices and other light commercial applications:

OmniCore Pro — PUMY-SP Range (R410A) of Outdoor Units:

  • PUMY-SP80 (10.0 kW Heating) Connect 2-7 indoors
  • PUMY-SP112 (14.0 kW Heating) Connect 2-8 indoors
  • PUMY-SP125 (16.0 kW Heating) Connect 2-8 indoors
  • PUMY-SP140 (16.5 kW Heating) Connect 2-8 indoors

Final outdoor unit selection will be affected by several different factors.

  • The combination of rooms and their location, as well as operating use, will determine which of the proposed models required
  • In many cases, an outdoor unit with a lower heating capacity may be adequate where not all indoor units are required to operate at full capacity simultaneously
  • If considering adding more indoor units in the future, in the interests of future-proofing, it may be best to select an outdoor unit capable of providing more heating capacity than is currently required

Optional Corrosion Protection Service to reduce the likelihood of pre-mature corrosion in coastal environments.

Limitations on Use

Every OmniCore Classic Multi Room outdoor unit has three parameters that determine the number and size of indoor units that can be connected to it:

  • 1. The number of indoor units that can be connected. Ranging from 2 to 8 indoor units dependent on outdoor unit
  • 2. The maximum individual indoor class rating that can be connected. Ranging from 15 to 100
  • 3. The maximum total class rating of all units that can be connected. Ranging from 75 to 202 dependent on unit

This product should not be used in the following situations:

  • In an area affected by heavy snowfall or blowing snow — in areas with heavy snow please install a canopy, a pedestal and/ or some baffle boards.
  • Within 3 metres from an antenna of TV set or radio. Operation of the air conditioner may interfere with radio or TV reception in areas where reception is weak. An amplifier may be required for the affected device.

Statement of Building Code Compliance

The full range of Mitsubishi Electric products have been tested and registered in accordance with MEPS (Minimum Energy Performance Standards) requirements.

It is also important to note that any heat pump outside unit installed without a compliant cover within 1.2m of a balcony rail will fall outside of these requirements.

Mitsubishi Electric highly recommend Heat Pump Covers Ltd products in these situations, and have many examples of successful OmniCore installations on multi-story apartment balcony spaces using Heat Pump Covers Ltd products.
