Section 12 - Sub-Systems
Superzone-CZS Sub-System
To create a Superzone Sub-System click the “Create Superzone System” button
to get to the Superzone Systems page. Click the “Add Subsystem” button.
Note:
Only certain versions of specific controllers are able to perform required sub-system functions. Refer to controller programming for the version of your controllers. Valid controllers and versions (or later) for Superzone sub-systems are:
SZ2182 - Version 1.4
SZ2166 - Version 1.2
SZ2181 - Version 1.4
SZ1025a - Version 1.4
SZ2165 - Version 1.4
SZ1018 - Version 1.4
For best sub-system operation, you should program all sub-controllers and master controller with desired parameters before setting up and programming sub-systems
Note:
QD2040-MAX is required to access the Superzone-CZS Sub-System.
• Controllers - First, scroll down to the bottom of the page to select
and configure sub-controllers before programming the subsystem Click
“Controllers” to expand the table of options.
Controller Selection - Click “Controller Selection” to expand the
table and select which controllers you wish to include in the subsystem. Only allowable controllers are selectable in this list.

Controller Detail – Click “Controller Detail” to expand the table
and select which controllers you would like to enable for voting. When the system is in voting mode, the controllers enabled
for voting will determine what action the entire system will take
depending on how many controllers are asking for heat or cool.
For example, if a majority want heating, then the system will
heat. Any controller with voting disabled is ignored when the system is in voting mode. You should also select which controllers
you would like enabled for discharge air temperature sharing. If
discharge air sharing is enabled for a controller, the discharge air
temp from the air handling unit will be shared to the controller.
This allows the zone controller to determine its heat or cool function according to the discharge air temp being supplied by the air
handling unit.
• System Parameters - Next Scroll to the top of the page to begin
programming the sub-system. Click “System Parameters” to expand
the table of options.
Sub-System Name – Enter a name that is descriptive of the use
and function of this Sub-System.
Master Controller – Select the main controller that is providing
the air handling unit control for this Superzone system from the
drop-down.
Note:
Only controls capable of acting as the Master Controller will be available
in the drop-down, including the SZ2181 and SZ2182. If you do not have
these controllers installed on the network you will be unable to create a
Superzone Sub-System.
Section 12 - Sub-Systems
Occupied Mode – Select the mode of operation for occupied
times from the drop down.
Cool Priority Mode - the system will provide cooling whenever at
least one zone is calling for cool.
Heat Priority Mode - the system will provide heat whenever at
least one zone calls for heat.
Voting Mode - the system will provide heat or cool according to
the highest number of calls from the zones.
Unoccupied Mode – Select the mode of operation for unoccupied times from the drop-down.
Note:
If Night Zone is selected, choose the controller that will take priority over
all others during unoccupied periods. If communication is lost to the
Night Zone, voting will occur.
Enable Backup Discharge Air Sensor – Check this box if you are
using a backup discharge air sensor, and then select the controller that has the backup discharge sensor connected to it from the
drop-down.

Note:
The Superzone system allows the discharge air sensor from the air handling unit to be shared over the network to other controllers on that SubSystem. In the event that the air handling unit loses communication capabilities, the system will use the backup discharge air sensor selected here.
Bypass Damper Control - Select the controller that will be used
for control of duct pressure form the drop-down.
Note:
If not using an SZ2182 AHU controller, which has built-in inputs and
outputs for pressure control, select the SZ1143b that will be used for
bypass damper control in this Sub-System.
Minimum Demand - Select the minimum number of control-
lers required to create an action. For example, if 4 controllers are
selected, then a minimum of 4 zones must be asking for heating
or cooling for the system to act.
Enable Tie Break Controller – If enabled, select a tie-breaking
controller. This controller will be the deciding factor if an equal
number of zones are calling for heat and cool. Only controllers
with voting enabled are included in this list.
Enable Priority Zone Controller – If enabled, select a Priority
Zone controller. This zone will receive priority over all others.
Once the priority zone is satisfied, normal voting will occur. Only
controllers with voting enabled are included in this list.
Majority Maximum Run Time - When multiple zones are calling
for heat and cool, this is the amount of time the majority will be
serviced. For example, if the majority is calling for heating, the
system will heat for this amount of time and will then switch to
cooling so the remaining controllers can be satisfied.
Minority Maximum Run Time - This is the amount of time given
to satisfy the minority group. Once this time expires, the system
switches back to satisfying the majority group and starts the cycle
over.
Section 12 - Sub-Systems
Enable Hot Deck/Cold Deck - Check this box if the Master
Controller is programmed for hot deck / cold deck control.
Enabling this function will only allow Master Controllers and
Secondary Master Controllers to turn on when required in unoccupied times.
Enable Secondary Boiler Master – Enable this function if the air
handling unit or zone reheat is being supplied by boilers or chillers and select the correct controller from the drop-down. SZ2165
and SZ2166 are the only allowable controllers for this function
Enable Secondary Chiller Master – Enable this function if a
separate controller is being used to control the chillers that are
supplying the air handling unit with chilled water and select the
proper controller from the drop-down. The SZ2165 and SZ2166
are the only allowable controllers for this function.
Hot Deck/Cold Deck Unoccupied Options - Allows you to configure how the system will behave during unoccupied periods if
Hot Deck/Cold Deck is enabled.
Enable Average Zone Temp High Limit – Check this box to allow
the system to turn on cooling if the average zone temp rises to
this value during unoccupied times.
Enable Average Zone Temp Low Limit – Check this box to allow
the system to turn on heating if the average zone temp falls to this
during unoccupied times.
Enable Individual Zone Temp High Limit – Check this box to
allow the system to turn on cooling if an individual zone temp
rises to this value during unoccupied times.
Enable Individual Zone Temp Low Limit – Check this box to
allow the system to turn on heating if an individual zone temp
falls to this limit during unoccupied times.
“Refresh Schedule” – Click the “Refresh Schedule” button to
activate the operational schedule of the Superzone Sub-System.
This function will check all start and stop times of controllers
within the Sub-System and operate the system based on the earliest occupied start time and latest occupied stop time.

• Demand Proportioning – The system can regulate the amount of
heat or cool provided depending on the demands from the zones.
Click “Demand Proportioning” to expand the table of options.
Enable on Heating (DO) - Selecting this option allows Ubiquity™
to regulate the amount of heating (digital outputs) depending on
the number of zones calling for heat.
Enable on Heating (AO) - Selecting this option allows Ubiquity™
to regulate the amount of heating (analog outputs) depending on
the number of zones calling for heat.
Full output at a percentage of the Systems Controls – Place a
value here to designate at what percentage of the system calling
for heat that all the heating stages will be on and/or the analog
heating outputs will be full open.
Enable on Cooling (DO) - Selecting this option allows Ubiquity™
to regulate the amount of cooling (digital outputs) depending on
the number of zones calling for cool.
Enable on Cooling (AO) - Selecting this option allows Ubiquity™
to regulate the amount of cooling (analog outputs) depending on
the number of zones calling for cool.
Full output at a percentage of the Systems Controls – Place a
value here to designate at what percentage of the system calling
