Wallplate installation
1. Separate wallplate from thermostat.
2. Mount wallplate as shown below.
MERCURY NOTICE
If this product is replacing a control that contains mercury in a sealed tube, do not
place the old control in the trash. Contact your local waste management authority
for instructions regarding recycling and proper disposal.
Grasp top and bottom of wa||p|ate
and pull to remove from thermostat.
CAUTION: ELECTRICAL HAZARD
Can cause electrical shock or equipment damage. Disconnect power before
beginning installation.
Drill 3/16” holes for drywall. Drill
7/32” holes for plaster.

Power Requirements
Wiring
Connect the common side of the
transformer to “C” terminal. This
connection is mandatory.
Remove tab.
The thermostat is shipped from the fac-
tory with the coin cell installed. To keep
the battery from discharging during
shipment and storage, the thermostat is
shipped with a plastic tab inserted in the
battery holder. This tab must be removed
during installation. Simply pull the plastic
tab out of the battery tray. Make sure
that the battery tray is fully inserted into
the thermostat.
Push excess wire back into the wall opening.
Plug wall opening with non-flammable insulation.
Remove factory-installed jumper
only for two-transformer systems.

Z-Wave messages
Association
The thermostat can be associated with other devices in the system. Being associated means
that the thermostat is able to send messages directly to any other device. During the asso-
ciation process the return route is acquired from the primary controller. The thermostat then
uses this return route to access the distant node.
Enter/leave power saving mode
When requested from the Z-Wave contro||er, the thermostat adjusts its setpoint in order to
decrease the power consumption of the HVAC equipment.
In addition, using an Internet gateway enables the person to control the thermostat remotely
through the Internet.
Fan Switch
The thermostat can send the message containing the actual fan switch position.
Fan Switch change
The other devices are able to change the fan switch of the thermostat. After the message is
received, the fan switch is changed to the desired value (if this value is possible).
For the thermostat the possible values are On or Auto.
Add/ Remove
The thermostat can be inc|uded or exc|uded from the Z-Wave network. This action requires
the contro||er set in inc|usion mode. The device is inc|uded to the Z-Wave network after
sending the node information to the controller. The controller is responsible for assigning the
home ID and device ID to the included device.
Indoor temperature
The thermostat sends the indoor temperature using the Multilevel Sensor command class.
Report upon GET request
Upon request (GET command} the thermostat sends the corresponding report.
Setpoint Value
The thermostat can send the message containing the actual setpoint value based on set-
point change.
TH8320ZW1000
13 69-2486—01
Z-Wave messages
Setpoint change
Other Z-Wave devices are ab|e to modify the setpoint of the thermostat. There are two
possible ways to adjust the setpoint. The absolute value can be sent by the controller and
thermostat will change the setpoint to this value. Or the relative change of setpoint can be
sent by the controller. In this case the controller sends just the value that has to be added or
subtracted from the actual setpoint value. The thermostat will add or subtract the received
value from the actual setpoint.
System Switch
The thermostat can send the message containing the actual system switch based on system
switch change.
System switch change
Other devices (controllers) are able to change the system switch of the thermostat. After the
message is received by the thermostat, the system switch is changed to desired value (if this
value is possible).
Five possible switch modes are available for the thermostat: Heat / Cool / Off / Auto
/ Em Heat. The number of allowed system switch selection depends on the actual
configuration of the thermostat. The thermostat uses "Thermostat Mode Supported" report
command class to tell other devices the actually supported switch modes.
Thermostat Fan State
The thermostat can send the message containing the actual state of fan based on fan state
change. The Fan state can be either "Auto" or "On".
Thermostat Operating State
The thermostat can send the message containing the actua| state of the HVAC equipment
based on equipment state change.
The thermostat provides the following operating states:
º Id|e - no equipment on
º Heating - heating equipment on
º Coo|ing - coo|ing equipment on
º Fan On|y - on|y fan is on
º Pending Heat - minimum off time app|ied to protect the heat pump compressor
º Pending Coo| - minimum off time app|ied to protect the heat pump compressor
Time/Date
The thermostat can send the message containing the actual Time and Date.
Time/Date change
The time and date is able to be changed on the thermostat. After the message is received,
the time and/or date is changed to the desired value (if this value is possible).
Unsolicited Report Message
Sending the message is possible only if the thermostat is associated with any other node.
The thermostat will send the message using assigned node ID and return route.

Special functions
Auto Changeover (Setup Function 0300}. When set to Auto, the thermostat automatica||y se|ects
heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 2
degrees apart.
Adaptive Intelligent Recovery (Setup Function 0530): Allows the thermostat to “learn” how long
the furnace and air conditioner take to reach programmed temperature settings, so the tempera-
ture is reached at the scheduled time.
Compressor Protection (Setup Function 0580): Forces the compressor to wait a few minutes
before restarting, to prevent damage. During this time, the message "Wait" ñashes on the disp|ay.
The THP9045 Wiring Modu|e is designed to be used with app|icab|e thermostats in 1 Heat/1
Coo| retroñt app|ications where on|y 4 wires are avai|ab|e. The K termina| on the thermostat
can be used to operate both the fan and compressor on a single wire, and the module is de-
signed to receive the signa| from the K termina|, sp|it that signa| and reroute it to operate the
compressor, and/or fan for normal operation. See the THP9045 manual for further details.
