The Zio Lite is configured using the same SBusWallModule wiresheet block as the Zio and Zio Plus, which
is located in the BuiltIn folder in the HoneywellSpyderTool palette. The configuration wizard has been
modified to include the new TR40/42 Zio Lite models.
Because the Zio Lite functionality is a subset of the Zio, it is fairly easy to set up.
Add the SBusWallModule block to the wire sheet, right click on the block, and select Configure
Properties to enter the configuration wizard.
Change the name in Block Name if desired, and then choose the TR40/42 you plan to configure (Fig.1).
If you choose a TR40 type, you will have just the general settings tab to set up (Fig 2).
Choose the wall module address. This address must match the bus address on the wall module, which is
configured using the dip switches on the back of the device.
Enter the F/C wiresheet units (required on TR4X models) and any offset to the sensor values if desired.
Click Finish, and you are done with configuration.
For TR42 models (Fig 3), you can also select International to reduce the amount of English in the tenant
view if you plan to have many non-English speakers using the device. You can also choose to make
Language an editable option for the tenant by checking the box.
Contractor set up at the wall module remains in English with either selection.
Unlike the Zio, the Zio Lite has just two fixed categories (Sensors and Setpoint), and just a few
parameters for the supported sensors and the temperature setpoint. It is not possible to create new
categories or parameters.
For ROOMTEMP, select the number of decimals you wish to show and then check the Viewable by
Tenant box if you want the tenant to see this value in the MORE screen on the thermostat. Enter a
default offset value if desired. Repeat these steps for HUMIDITY .
If you choose not to View any values, then there will be no access to the MORE screen. "MORE" will not
show up in the display, and that softkey will be inactive. See "About the MORE screen" further down.
The F/C units shown in the display for measured room temperature will be the units chosen for the
Tempstpt (Temperature Setpoint).
About the MORE screen in Zio Lite
The MORE screen in Zio Lite is accessed by one of the soft keys on the wall module. Normally, the
tenant will have access to the room temperature and the setpoint, but if you have a model with
humidity or CO2, you can also allow the tenant to view these by either pressing the MORE softkey. If
both softkeys are being used(Override and Fan are both active), then pressing the up and down arrow
keys simultaneously will always access the MORE screen.
View or Hiding values in the MORE screen can be done by checking or not checking the "Viewable by
Tenant" check box in the tool.
Values possible for viewing in the MORE screen are: Room Temperature, CO2, Humidity, Temperature
Setpoint (editable), Device Name, Language (editable), and degree F/C (editable).
If you choose not to View any of these values, then there will be no access to MORE. "MORE" will not
show up in the display, and that softkey will be inactive.
The temperature setpoint can be displayed numerically or graphically on the Zio Mini, as shown.

If Numerical is chosen, a number will be shown in the display. This could be either an absolute value,
say 70, 72, etc., or a relative offset value, say +/-5.
If Graphical is chosen, a graduated line graph will appear on the display with COOLER to the left and
WARMER to the right. Pressing up or down will cause the cursor to move left and right. The graph will
be set up so that it is scaled linearly to the low and high limits you enter, with the low limit value being
the far left position, and the high limit value being the far right position. It will do this whether you set
up your limits for an offset or a center setpoint value. The graph is divided into exactly 20 segments.
These segments do not correspond to a fixed temperature amount, since the graph can be scaled
differently. The output will be in either 1.0 or 0.5 degree increments, even in the offset mode,
depending on what you choose in this tab.
The setpoint in a controller can be set for either an offset setpoint (when the value is below 10) or a
center setpoint (when the value is above 10). Set your low limit and your high limit in this tab so that
your output will be an offset (say -5 to +5) or a center setpoint (say 55-85F, or 15-25C), as desired. Do
not exceed high and low limits of +/-9 for an offset value.
NOTE: It is not possible to change between relative "offset" setpoint and center setpoint from the wall
module. This change must be made at the tool and downloaded. You can still choose between
graphical or numerical setpoint at the wall module.
You can show the offset setpoint either graphically or numerically, and you can show the center setpoint
either graphically or numerically. It is most common to set either a numerical center setpoint or a
graphical offset setpoint, but the other two choices will function as well.
Choose the Display Unit. This unit applies to both the setpoint and the room temperature at the wall
module display.
Choose the Wiresheet Unit. This is the unit you are using in the wiresheet logic. This is a new
requirement for the TR40/42 family, and is not required for the TR7X family.
Only one value can show up in the home screen at a time. You have a number of choices. Temp or
Temp Setpoint are probably the most common choices, but you can also choose other values listed. If
you choose not to check the View by Tenant box for any of these items, they will still show up on your
home screen if you choose one of them in this Home Screen Options tab, including the scrolling
function. You just won’t have them showing up in the MORE screen.
If you choose Device Name, the Block Name you chose in the General Settings tab will show up in the
Home Screen, handy if you don’t want tenants to view anything at all on the home screen, and also
provides a way to identify which wall module is attached to which piece of equipment (VAV1, RTU2,
etc).
If Scrolling Screen is chosen, the Zio Lite will continously scroll through all of the following values if they
are marked as Viewable/Editable by Tenant: Temp, Temp setpoint, Humidity, CO2 and Device name.
Selecting "Enable Occupancy Override" will allow the user to override to a bypass time into the occupied
mode. You can choose to "Use Network Bypass Time Only", or use a timed override which is selectable
in the drop down menu. There is no option to override into unoccupied mode on the TR42. The TR42
will always show the effective occupancy on the display.
Override time will only be supported from 1,2,3,4,5,6,7,8,12,16,20,24 time intervals.
Click this tab if fan access is needed. Choose the fan type and default state of the fan. This set up is
identical to the TR7X.
If a password to the installer menu is desired, check the Password tab and choose a four digit password.
If no password is needed, skip this tab.
Warning: There is no backdoor to accessing this password, so write it down and keep in a safe place,
especially in stand alone applications. The password can only be accessed via this configuration tool.
Click finish and you are done. As with the Zio, you can save your wall module configuration to a library.
Listed below are the fields that will be available as NCIs on Spyder. You can readily access these in the
points folder for use in px pages, etc. All of these settings are also configurable directly in the wall
module in the contractor setup menu, accessed by pressing both upper keys for five seconds.

**Caution: If an invalid network value is sent to any of these fields, unintended behavior may result.
Be sure you are sending valid network values. See Table 2 for information on ordinal values.
For each field an entry will be present in the send table of Spyder to send that value to TR4x whenever
Spyder receives a new value over Lon/Bacnet network.
The following values will be sent from TR4x to Spyder for use in Spyder Logic and for calibration. You
can also calibrate sensors directly at the wall module.

*(X) - Sylk Device Address
How many Sylk Wall Modules are supported?
Sylk Device Capacity is determined by Sylk memory (Proxy), Sylk power consumption and Sylk
bandwidth. All of these are now dynamically determined in the Spyder Resource Usage view in the workbench, example shown in fig 10.
The bandwidth for sylk devices can change depending on the number of messages being sent per
minute (so it is highly dependent on number of parameters set up for TR71 and TR75). Once all links to slots
on the device block are made, go to the Resource Usage view and check to make sure you are less than
the 100% on Proxy, Power, and Bandwidth.
A Sylk Capacity Tool is available on the Buildings Forum that will allow you to enter different
combinations of sylk devices (Zios, sensors, SylkIO, Zeliz actuators) to see if they exceed limits or not.
The TR42 allows many of the same configurations in the tool to be made at the device as well.
Configuration changes made at the device are automatically uploaded to the Spyder and preserved.
Remember to upload the Spyder application to the tool before making changes in the tool if you want to
preserve configuration changes made at the wall module.
From the HOME Screen, enter the Configuration menu by pressing the two upper softkeys
simultaneously for 5 seconds. Then enter the password if one has been set up.
The wall module allows the installing contractor to configure the following items:

Be sure you are sending valid network values.
Simply scroll through each selection with the up/down keys, click EDIT to make the changes desired.
Click DONE to accept changes to each configuration, and click HOME to exit the configuration menu.
When the wall module is initially powered up by connection to Sylk, the default configuration upon
power up is determined by the tool and downloaded to the Zio Lite from the Spyder.
While at the Main Screen, pressing up or down will allow the user to adjust the occupied temperature
setpoint. If the system is in unoccupied, user must press OVERRIDE to switch to OCCUPIED.
Pressing the OVERRIDE button (if it is enabled) will allow the occupant to override into the occupied
mode for a comfortable temperature. The duration of this override is determined by the installer.
Pressing the FAN button (if it is enabled) will allow the occupant to adjust the fan speed.
Pressing the MORE button (if enabled) and them pressing the up/down keys will provide the occupant
with additional information, including (if enabled) the ability to switch the units between °F and °C. If
both the Fan and the Override softkeys are enabled, then the MORE menu can be accessed by pressing
the up and down arrow keys simultaneously. If either Fan or Override keys are not enabled, one of
these softkeys will appear as the MORE softkey.
