ZIO CONFIGURATION SCOPE
This document serves as a technical users guide for an
installer who is configuring a Stryker VAV controller via a
TR71 or TR75 wall module. Parameters are grouped into
logical categories rather than on large list. To access the
“Contractor” mode for configuration, press the Up, Down and
middle keys simultaneously. During this time the model
number and firmware revision of the TR71/75 will be displayed
and then you will be prompted to enter a password (default
0000) to enter the Contractor mode. You can then navigate to
the desired category of parameters and then begin
configuring and viewing information from the device. Each
screen below has a brief explanation of the data, and in cases
where the data can be changed, the corresponding network
variable is shown in brackets. For example, the “MAX FLOW”
parameter that is found in the “BALANCE” category is
manipulating the MaxMeasFlowAct section of the
nciBalanceSetPts structured nci and is noted as
[nciBalanceSetPts, MaxMeasFlowAct]. Values within the
Contractor mode are only viewable in English (U.S.) units of
measure. Temperatures however CAN be shown on the home
screen as C or F.

TENANT VIEW MORE
NOTE: To add or remove items from the Tenant View
More sequence use Contractor Mode by holding
the up, down and center buttons for 5 seconds.
During this time the display will show the model,
firmware version and Sylk bus address of the
TR71/75. Select “SetViewMore” to add or remove
items by choosing “YES” or “NO” with the up/
down buttons.
Center Setpoint Temperature
NOTES:
1. The center setpoint can be disabled using Con-
tractor View: WM_CONFG, CNTR_SP, FALS or
true.
2. If CNTR_SP = FALS, the set point can be
changed, however the value is ignored.
3. The range can be controlled by WM_CONFG:
CNTSP_HI, & CNTSP_LO
4. To remove the CNTR_SP from the View More
screen use Contractor Mode: SetViewMore, SET-
POINT = NO
