THERMOSTAT LOCATION
The Z2000RT 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 Z2000RT, 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 sub-base then level and
mount the sub-base on the wall using the supplied anchors
and screws. Do not over-tighten the mounting screws as the
sub-base may warp causing improper seating of the thermostat
connecting pins to the terminal blocks. Use a properly sized
screwdriver and terminate 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 Z2000RT contains a set of dip switches numbered
1 through 8. Only dip switches 1, 2 and 3 are active.
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
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
is used to select two-position (ON position)
or fully modulating (OFF position) damper control to
best suit the specific application requirement.
