All the features of the UniPoint RF plus:

  • From 1 to 4 hard wired wall controllers strategically placed through the house. (No more having to go downstairs in the middle of the night to turn off the system with a controller in the master bedroom AND the kitchen
  • Up to 8 zones with the ability (via an expansion module) to go to 16 zones (for large or two story buildings)
  • The ability to group zones together for convenient usage (if you have a big family room with, maybe, three outlets, they can be programmed to open to different levels to give varied flow around the space BUT still all open or close at the same time (programming zones into a group gives you better control and more convenient operating
  • A programmed service reminder. Your installer can programme in a forward service reminder for uo to 108 days away so you are reminded to get the filters cleaned, routine maintenance BEFORE the system getsa choked with everyday dirt and starts using more power/ working less efficiently
NOTE: Air Conditioning Systems are not 'set and forget' systems, they require similar regular servicing to a car or any other large machinery to continue operating at peak efficiency

System Balancing

The installer may spend hours climbing in and out of the roof to adjust airflow to each room to make sure all rooms get adequate flow. Unfortunately, in many cases this may be difficult to achieve in the alloted time

Example: Often yhe room that is at the end of the longest duct run gets little or no air because of improper balancing.UniPoint RF & MaxiPoint V2.0 solves the difficult job of zone/ system balancing

With the unique Zone balancing ability of UniPoint RF and MaxiPoint V2.0 this difficult task becomes smiple and easy, guaranteeing a good result every time.The installer uses the wall mounted (MaxiPoint), or the handheld (UniPoint RF) controller to adjust the dampers in the roof WHILE HE's IN THE ROOM checking the airflow. No more climbing in and out of the roof. He just stands in the room to check airflow is satisfactory as he adjusts all the dampers from the control. Fast and easy for him, a far better result for the client.
Note: the volume of available air is dependant on the size of the Air Conditioning Unit and also on satisfactory ducting design

The UniPoint RF System makes any ducted system more efficient by allowing air flow to rooms being used and stopping wasteful flow to unoccupied.

Imagine you are sitting in the lounge after dinner and the kids have gone to bed. It's been a hot day and everyone will need maximum cooling to get a good night's rest. You use your Zonemaster UniPoint control to shut off all zones except the bedrooms. Restricting the airflow to the areas you need increases the available cool air and doesn't waste power on cooling unoccupied rooms.

Maximum cooling for a comfortable night
 

  • Manual and programmable on/off time control
    So you can programme it to turn on and off at set times but still manually override.

  • LCD indicator for zone status/ parameter display
    Gives you easily visible indicators of system activity

  • Real time clock with battery backup

  • 5-1-1 Zone on/off program (5 Weekdays Sat/ Sun)
    One programme to set up for weekdays and seperate ones for Saturday and Sundays allow for different work and leisure needs

  • Personalised zone labelingLets you call each zone its proper name (e.g Kitchen,Boardroom, Sue's Bedroom, Games Room, Bill's Office)

  • Easy Installation (24 volt plug)
    Low voltage installation don't require a qualified electrician which is a big saving.

  • Safety Protection
    • Srops damage to the duct system
    • Auto spill/ bypas - the designated spill zone is open if all zones switched off (to prevent duct blow off)
    • Temperature override - opens all dampers if air supply temperature is lower than low limit or exceeds highlimit
    • After power loss all zones automatically return to previous on or off state when power restored.

BENEFITS:

  • Managing airflow so that the (cool or warm) air is only directed where you need it creates energy savings and greater comfort.
  • The programmable timer means that the zones can be set to open and shut at specific times for maximum efficiency.

Plus the following additional features:

  • No messy wall installation problems (ideal for older houses with hard plaster walls
  • Variable frequency (so it doesn;t interfere with the neighbours unit)
  • RF remoce control handset so you can keep it by your chair od bedsite
  • Backlit LCD screen for easy reference (on the handset for zone status and parameter displayM
  • Turbo zone for quick cooling on one designated room or space (so you can cool a roomdown quickly if needed
    -ideal for a bathroom or games room that might have an unexpected influx of people)
  • Remote Balancing is unique to Zonemaster Products
Principles of Zone Management for Efficient Ducted Air Conditioning Use

A Basic Ducted Air Conditioning Unit is installed with duct and outlets to all spaces requiring heating or cooling. The temperature will be regulated by the single temperature gauge in one spot in the building. Usually the Kitchen or Hall there is no regulation as to how much air will go into each room.
This doesn't take into account variables such as:

  1. Rooms with a lot of glass may be hotter than rooms with small windows
  2. Rooms getting afternoon sun will be hotter than rooms on the shady side of the house.
  3. In large houses, outlets a long way from the Air Conditioning Unit may not receive a sufficient amount of air flow

Any house, office or other space consisting of various rooms can, for the sake of Air Conditioning Efficiency, be divided into sections (or zones) and the air flow to each controlled by a motorised damper(s) that will, in turn, better manage temperature level.

These Zones could include:

  1. Day & Night Zones
  2. Separate Usage Zones (Kitchen & Lounge/Kitchen & Bedrooms/Kitchen & Dining /Games)
  3. Specific Work usage (offices/Boardrooms)

The air conditioned space can then be selectively regulated via the dampers so that only the spaces in use have airflow. For Example:

  1. When there is little need to heat or cool bedrooms that are not in use during the day
  2. An office boardroom doesn't need continuous airflow when it may only be used once a week.

By confining air flow to the spaces being occupied the A/C unit is allowed to work more efficiently and, because the whole volume of air is going into a smaller area, desired temperatures are reached quicker and maintained more easily.

Managed Air Flow

The air flow to each zone is managed via a Motorized Damper which can be turned on or off by the Electronic Managemnent system. The Motorized Damper can be a simple in line version, or the more sophisticated Polyaire Diffusion Fitting which expertly manages the airflow to 4 outlets from a central point close to the Air Conditioning unit for optimum airflow to all outlets.

The latest design complete air management fitting from polyaire.
Fully externally insulated, no joins to leak and designed to take motorized or manual dampers to tune your system for optimum efficiency, this fitting also uses a specially designed Zip Tie connector system to virtually eliminiate duct join leakage and provide the best possible seal against air loss.
the Zip Tie connector system won't loosen with time and ensures that all the airflow goes into your rooms, not into the ceiling

Installing A Zone Management System to manage the Airflow from your Ducted Air Conditioning Unit can:

  1. Reduce your energy cost

    2. Zoning permits you to reduce energy costs by not heating or cooling an area of the home or office that is vacant. Shutting unused zones off sends all available capacity of the heating or cooling system to areas that are occupied, enabling then to reach set temperature more economically
  2. Contribute to more rapid temperature recovery

    3. By shutting down less important zones an particular hot or cold days will bring more important zones closer to sedires temperature more quickly
  3. Help you save money by allowing for the use of a smaller Air Conditioning Unit

    4. If a large house is calculated to need a 20 Kilowatt (For Example) Unit to effectively heat & cool the entire structure but further examination shows that, at any given time, only two thirds of the rooms/ space are in use, then with well designed zoning it is possible fot the house to be satisfactorily serviced by a much smaller unit, providing a major up-front cost saving and ongoing power saving through ther life of the unit.
    How well each zone can be regulated depends on the sophistication of the Damper Control System being used.

    NOTE -Many Ducted Air Conditioning Systems now come with basic Zone Management Systems included but few, if any, feature the sophisticated electronics of the Zonemaster UniPoint RF & MaxiPoint V2. These two systems can actually regulate the amount that each damper opens so that the whole system can be 'balanced' by your installer to ensure sufficient flow to every zone all the time. These systems work independently from the Air Conditioning Unit
