DISASSEMBLY
Insert a small coin (dime) in the release
slot located on the bottom of the
thermostat. Gently twist the coin to
release the thermostat from the
subbase. Avoid twisting the case, as this
may stress the LCD and cause it to
crack or bend the terminal pin
connectors.
TERMINAL DESIGNATIONS
The Z-2000-T has dedicated screw
terminals located on the subbase to
facilitate ease of wiring to the actuator
board mounted on all Z-2000™ and
Zone One™ dampers. When wiring the
Z-2000-T to the actuator board, use
standard 18-8 thermostat (verify with
local codes if plenum rated wire is
required).

THERMOSTAT LOCATION
The Z-2000-T should be installed in a
location that represents the ambient
space temperature. Do not install the
thermostat in an area where drafts are
present, near the floor, behind doors or
on an external wall. Avoid placing the
thermostat in areas where the air
movement is limited, affected by direct
sunlight or other areas not typical of the
temperature in the space.
MOUNTING THE SUBBASE
When mounting the Z-2000-T, be aware
that drafts may travel down wall cavities
and enter the back of the thermostat
through the control wire hole in the wall.
It is important to seal the hole to prevent
any drafts that might affect the internal
temperature sensor.
Pull the control wires through the large
opening in the thermostat subbase then
level and mount the subbase on the wall
using the supplied anchors and screws.
Do not over-tighten the mounting
screws as the subbase may warp
causing improper seating of the
thermostat connecting pins to the
terminal blocks.
Use a properly sized screwdriver and
land each wire to its dedicated terminal.
Do not over-tighten the terminal
screws.
Check to see that all wires are landed
correctly and dressed properly to
prevent any shorts.
SWITCH FUNCTIONS
The Z-2000-T contains a set of dip
switches numbered 1 through 8. Only
dip switches 1, 2 and 3 are active.
Switch 1 - Switch 1 is used to lock the
thermostat after setup is completed.
When the thermostat is locked (ON
position) a padlock icon will show on the
LCD. When locked, only setpoint
changes and status functions can be
accessed by the user. Do not set
Switch 1 in the ON position until all
setup functions are completed.
Switch 2 - Switch 2 is used to display
the space temperature, duct
temperature and setpoint in Celsius (ON
position) or Fahrenheit (OFF position).
Select Celsius or Fahrenheit before
proceeding to the thermostat setup
menu.
Switch 3 - Switch 3 is used to select
two-position (ON position) or fully
modulating (OFF position) damper
control to best suit the specific
application requirement.

SETTING A ZONE NUMBER
Press the SETUP key again and the
LCD will display the word ZONE. The
factory default is 00. This number can
be used to identify each Z-2000-T
thermostat wired to a Z-2000™ zone
control panel or when used in multiple
stand-alone applications. Use the UP
and DOWN keys to assign a ZONE
number from 00 to 99. (Figure 6)
SETTING THE HEATING LIMIT
Press the SETUP key again and the
LCD will display the heating limit. The
factory default is 76° F. Press the UP
and DOWN keys to change the heating
limit setting. It is strongly recommended
that the limit not be set above the
factory default setting. (Figure 7)
SETTING THE COOLING LIMIT
Press the SETUP key again and the
LCD will display the cooling limit. The
factory default is 68° F. Press the UP
and DOWN keys to change the cooling
limit setting. It is strongly recommended
that the limit not be set below the factory

factory default is 90 seconds which is
the time it takes the actuator to drive the
damper blade fully open or fully closed.
This is a critical step in the Z-2000-T
setup since the thermostat can be used
with a variety of 24 Volt actuators. If you
are unsure of the actuator speed, place
the actuator in the fully closed position
and then apply 24 Volts to common and
normally open. The time it takes to drive
the damper blade fully open equals the
actuator speed setting. (Figure 9)

Systems at 1-888-652-9663 or
[email protected]. (Figure 10)
TEMPERATURE CALIBRATION
OFFSET
Press the SETUP key again and the
LCD will display the temperature
calibration offset. The factory default
setting is 0. Typically, it is not necessary
to adjust the temperature calibration
offset as the Z-2000-T has been factory
calibrated. If calibration is necessary, a
high quality electronic digital
thermometer must be used. Place the
thermometer sensor probe next to the
thermostat sensor and allow five
minutes before comparing the
temperature readings. Use the UP and
DOWN keys to adjust the temperature
calibration. The range is +/- 9° F.
