4.4.1 Set Present Zones
Z-Plus Touch can adjust its display so that only present zones appear. Press the
+
or
-
soft
keys until the appropriate number of zones is displayed.
4.4.2 Set Motor Time
Z-Plus Touch utilises a time proportional damper positioning algorithm. For the system to
function correctly all zone damper motors must be the same type.
Livezi offers 2 motors with different drive speeds for use with Z-Plus:
The Livezi motors require the motor drive time to be set to 16 seconds (default).
The Belimo motors require the motor drive time to be set to 45 seconds. Press the “Motor”
button until the correct motor type is displayed.
4.4.3 Maximum Capacity
Z-Plus provides an ability to adjust the peak system capacity to match perfectly the peak load.
Most residential systems are sized on the peak cooling daytime load. If the standard sizing
calculation has been used, set the Maximum Capacity to equal the area used in the capacity
calculation.
4.4.4 Configure Favourites
Z-Plus includes the ability to group zones together so they can be controlled simultaneously.
The favourites will appear at the end of the zone names and include individual time clock
programs. To group zones press the “Cfg Faves” button in the system configuration screen. At
the top of the screen the Favourites name will be displayed (default is Fav a ~ Fav d). Group
zones by pressing the button beside each zone name.
4.4.5 Calibrate Touch
Z-Plus Touch utilises a four wire touchscreen. After extended use it may be necessary to re-
calibrate the display. Calibration is completed in the factory before shipping so this process
does not form part of the system commissioning procedure. If calibration is necessary activate
the mode by pressing the “Calib Touch” button and following the steps. Make certain that you
use the stylus provided and take care to activate the centre of the “X” targets.
4.4.6 Service Timer
Z-Plus Touch incorporates a service timer that logs the run time of the indoor fan. Programmed
maintenance is required to satisfy the warranty coverage conditions and the Service Timer is
an excellent way of scheduling programmed maintenance. A custom contact number can be
added so that when a service is required the contact details are available to the home owner.
