Introduction
Thank you for choosing temperzone for your heating, cooling or air conditioning
system zone control management. You have chosen a product built to exceptional
standards and that offers that latest’s technology in energy management and comfort
control.
Please take the time to read these instructions and familiarise yourself with the
features and functions found in this product.
What Is Zoning?
Climate system zone control allows the user managed distribution of conditioned air
(warmed or cooled) to specific arrears of the home or office to permit the increase of
comfort levels or/or the reduction of energy costs.
Just as your home or office has a number of light switches to control which rooms are
lit, your zone control system permits you to control which rooms are heated or cooled
and in most circumstances, what temperature is maintained in these rooms (or zones).
When using a zone control system, it is important that realistic demands are made on
the system such as keeping all the zones desired temperatures to within 5 to 8c of
other zone temperatures or of the TZT-100 thermostat set temperature.
Advantages of Zoning
Reduced energy Costs
Zoning permits you to reduce your energy costs by not heating or cooling an
area of your home or office that is vacant. Shutting unused zones sends all
available capacity of your heating or cooling system to zones that are
occupied, enabling them to reach set temperature faster - saving energy.
Rapid temperature recovery
By shutting down less important zones on particularly hot or cold days will
bring more important zones to set temperature more quickly. Turn off the
unoccupied bedrooms during day to ensure the living area temperature is
effortlessly and efficiently maintained.
More even temperature Control
The EASY ZONE TOUCH will enable you to turn zones off manually when they
become too warm or cool, so turn off upstairs when the temperature is
warm enough while leaving downstairs to continue to heat.
Page 5
The EASY ZONE TOUCH can automatically shut some zones down when a
zone preset temperature has been reached if configured by your installer.
Smaller Heating or cooling system required.
As zoning is such an energy efficient method of climate control, it is often
recommended that a smaller than normally required heating and cooling
system be used. This saves money as a lower capitol investment and in
ongoing energy bills.
Disadvantages of Zone control
Many heating and cooling systems must maintain a minimum volume of air
through the system for them to work effectively. As zones are closed the
volume of air through the heating and cooling system may be reduced and if
too many zones are simultaneously closed while the heating or cooling
system is running, the heating and cooling system may shut down to protect
itself.
The EASY ZONE TOUCH will attempt to prevent this by automatically opening
all zones if it detects stress on the heating and cooling system.
Further, shutting too many zones down will increase air velocity through the
open zones which now may become noisy. Using the TZT-100 thermostat
permits you to control fan speeds permitting you to manually select a lower
fan speed to eliminate or reduce this problem.
Your installer will have set a limit on the number of zones you are permitted
to have closed at any time. Further, “spill” or bi-pass zones may be installed
and open / close automatically based on the number of zones you have
selected as open or closed.
Operation
The Easy Zone touch is a advanced touch screen device capable of actively controlling
up to 6 temperature controlled zones.
Without applying great pressure and using your finger tip or fingernail you are able to
operate the system and turn zones on or off and set zone temperatures as required.
The EASY ZONE TOUCH will respond to all valid “touch” commands with a confirming
“beep” and the new status will be displayed on the LCD. Any illegal requests will be
greeted with multiple beeps and a message on the bottom of the screen informing you
of the correct problem.

Screen layout
Zone Name
There is provision for a 10
Character name to be
associated with each zone to
help you identify that zone.
Your installer will have set
the zone names as part of the installation process. You can also adjust the zone name
in the “More” window and selecting “Names”.
Function
Your EASY ZONE TOUCH will be setup by your installer to either simply open or close
the zone(s) or to report the zone temperature to the TZT-100 thermostat. Aditionally
the EASY ZONE TOUCH can automatically open and close the zones based on zone,
actual temperature and the zone desired temperatures.
Zone Status indication
Tapping the zone button will permit you to cycle between the available modes as set
by your installer.
Zone Off
This is showing that the “Rumpus” zone is OFF. No
conditioned air will be sent to this zone.
Zone ON
This is showing that the “Rumpus” zone is ON. This zone is
receiving conditioned air from your heating and cooling
system.
Zone Sensing
This is showing that the “Rumpus” zone is ON, and the
temperature in this zone is being monitored by your
heating and cooling system which will then control the
system accordingly.
Zone Active
This is showing that the “Rumpus” zone heating and
cooling desired temperatures are being actively
maintained by the EASY ZONE TOUCH.
Zone Spill
If set by the installer, Zone one (the top left zone) may
automatically open or closed based on the number of
other zones that are in use. If this zone is automatically
opened the word “SPILL” will be shown
Page 7
Pressing and holding the zone button will enable Active Zone temperature adjustments
if enabled. Pressing and holding again will permit you to adjust the Active Zone set
point values.
System messages
Various messages will be shown in this section of the screen to alert, inform or assist
the user in the use of the EASY ZONE TOUCH control panel. See appendix 2 (Page 10)

Press this button to enter a sub menu that permits you to adjust screen brightness,
contrast or perform other rarely used functions
Screen Calibration
If the touch screen accuracy is poor, you are able to calibrate the screen. Press the
“More” and then select calibrate. Follow the on screen prompts and touch the three
crosses as accurately as possible when prompted.
Note: It is recommended that when calibrating the screen that you use the cap of a
ball point pen or other blunt pointy device for greater accuracy.
This normally only needs be done once.
Turning a Zone on or off
Tap the zone name to toggle the zone between On or OFF modes. If enabled by the
installer, tapping this button again will also permit you to select “Sensing” mode where
the zones temperature will be used by the TZT-100 thermostat to control the heating
and cooling system to control that zones temperature. As each tap of the button is
detected a Beep will be heard and the status of the zones will change.
Again, if enabled by the installer you can press and hold the zone button to permit
Active zone temperature control where the EASY ZONE TOUCH will limit the zone
temperature independently of the main thermostat.
To turn Active mode off simply tap that zone button again.
Setting the Zone Active Temperature (if function enabled)
The Easy Zone has the ability to monitor the zone temperature and, if enabled by the
installer automatically open or close the zone based on the current zone temperature,
the current room temperature and the current status of the heating and cooling
system. So, if the zone is a little warm and the heating system starts, the EASY ZONE
TOUCH will automatically close the zone to prevent the zone from further overheating.
If the cooling starts the EASY ZONE TOUCH will open the zone to permit the zone to
Page 8
cool to the cooling set temperature if necessary. The heating set temperature should
always remain lower than the cooling set temperature.
To adjust the zone temperatures
Press and hold the
zone button for 2
seconds, the LCD will
change to show the
zone temperature
adjustment screen as
shown right.
Zone name
This is the unique name given to the zone where to help identify it.
Zone temperature
The current zone temperature as measured in the zone by the zone wall temperature
sensor.
Cooling
When the cooling system is running the EASY ZONE TOUCH will close the zone damper
when the room temperature is at or below this value. Touch the temperature to select
it for adjustment with the temperature set button. It will highlight to show it has been
selected. (Cooling is selected in the above example).
Heating
When the heating system is running the EASY ZONE TOUCH will close the zone damper
when the room temperature is at or above this value. Touch the temperature to select
it for adjustment with the temperature set button. It will highlight to show it has been
selected. (Cooling is selected in the above example).
Zone Status
This shows whether this zone is receiving conditioned air based on the room & set
temperatures and the mode of the air conditioning system. In the above example the
zone has been automatically selected to off by the EASY ZONE TOUCH, as the current
room temperature is between the desired heating and cooling set temperatures.
Temperature Set Buttons
Select the heating or cooling desired temperature and then adjust with these buttons.
Back
Select back to save changes and return to the previous menu, or wait 30 seconds and
the easy Zone Touch will automatically return to the previous menu.

EASY ZONE TOUCH Safety Systems
As the EASY ZONE TOUCH does not directly control the heating and cooling system,
(turn the heating & cooling system on or off directly) it simply reports the zone
temperatures to the TZT-100 thermostat. The TZT-100 thermostat then controls the
heating and cooling system based on the “sensing” zone temperatures and
thermostats set point. This zone control strategy offers the most flexible control and
impacts least on the heating and cooling system electronics.
A number of innovative passive and active protection strategies have been
incorporated into the EASY ZONE TOUCH design to protect the heating and cooling
system. Therefore, depending on the requirements of your installation you may find
that the EASY ZONE TOUCH makes some demands of you as setup by the installer.
Some restrictions may include some or all of the following
Not being permitted to close all zones simultaneously.
Not being able to open all zones simultaneously.
Keeping at least one zone as a “Sensing” zone at all times.
Limiting the maximum number of “Active” zones.
System messages on the status bar will guide you in using the EASY ZONE TOUCH. For
example, if you want to close the bedroom zone and you not permitted, simply open
another zone first and then try closing the bedroom zone. This ensures that a sufficient
number of zones are open at all times to maintain the necessary air flow through the
heating and cooling system for safe operation.
Performing a Reset
The EASY ZONE TOUCH is a microprocessor based device
and in rare circumstances or as a consequence of power
surges or the like the EASY ZONE TOUCH may become
erratic or unresponsive and need to be reset. Simply press
the reset button with a thin blunt object such as a ball point pen or a straightened
paper clip to perform this function. No user or installer settings will lost when a reset is
performed.
