Connect the common side of
the transformer to “C” terminal.
This connection is mandatory.
Remove tab.
The thermostat is shipped from the factory
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 dur-
ing installation. Simply pull the plastic tab
out of the battery tray. Make sure that the
battery tray is fully inserted into the ther-
mostat.
Push excess wire back into the wall opening. Plug
wall opening with non-flammable insulation.
Remove factory-installed jumper

node information to the controller. The controller is responsible for assigning the home ID and
device ID to the included device.
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 associa-
tion 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

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, Auto and Circ.
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 setpoint

Setpoint change
OtherZ-Wavedevicesareabletomodifythesetpointofthethermostat.Theabsolutevaluecan
be sent by the controller and thermostat will change the setpoint to this value.
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 seven).
Seven possible switch modes are available for the thermostat: Heat / Cool / Off / Auto / Energy
Saving Heat / Energy Saving Cool / 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 system 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actualstateoftheHVACequipment

Time/Date change
The time and date is able to be changed on the thermostat. After the report 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.

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 temperature is
reached at the scheduled time.
Compressor Protection (Setup Function 0580): Forces the compressor to wait a few minutes before

Cool retrofit applications where only 4 wires are available. The K terminal on the thermostat can
be used to operate both the fan and compressor on a single wire, and the module is designed to
receive the signal from the K terminal, split that signal and reroute it to operate the compressor,
and/or fan for normal operation. See the THP9045 manual for further details.
