K M32429 Connect the common side of the transformer to “C” terminal. This connection is mandatory. M32428A 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 during installation. Simply pull the plastic tab out of the battery tray. Make sure that the battery tray is fully inserted into the thermostat. Wiring Remove factory-installed jumper only for two-transformer systems.

Z-Wave enrollment The TH8320ZW is powered by Z-Wave technology so it is compatible with Z-Wave enabled devices from other manufacturers. 1. To join a Z-Wave network, set the Z-Wave controller to INCLUDE mode. 2. Select 1 to add thermostat to Z-Wave network. F 10 0 DONE M32423A 69-2486—09 10 TH8320ZW Z-Wave enrollment Wait F 10 M32422 3.

To share the thermostat Node information with additional Z-Wave devices select 1. F20 0 DONE M32421 Z-Wave messages Add/ Remove The thermostat can be included or excluded from the Z-Wave network. This action requires the controller set in inclusion mode. The device is included 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. The thermostat can also act as a repeater to forward messages to other devices in the Z-Wave network. Repeating messages allows communication of devices that are not in the direct reach of Z-wave protocol. 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 association process the return route is acquired from the primary controller. The thermostat then uses this return route to access the distant node. The association is a connection between primary and secondary devices. It is used to determine the relationship of devices in the network. Both primary and secondary controllers can set up associations. The thermostat supports one association grouping and five nodes can be associated with this grouping. Following messages are sent to associated nodes for grouping #1: · Basic · Multilevel Sensor · Thermostat Mode · Thermostat Setpoint · Thermostat Fan Mode · Thermostat Operating State · Thermostat Fan State Enter/leave Power Saving Mode When requested from the Z-Wave controller, 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. Thermostat Fan Mode Change The thermostat can send the message containing the actual fan mode position. Thermostat Fan Mode The other devices are able to change the fan mode of the thermostat. After the message is 69-2486—09 12 TH8320ZW Z-Wave messages received, the fan mode 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 change. 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. Thermostat Mode Change The thermostat can send the message containing the actual thermostat mode based on thermostat mode change. Thermostat Mode Other devices (controllers) are able to change the thermostat mode change of the thermostat. After the message is received by the thermostat, the thermostat mode change is changed to desired value (if this value is possible). Seven possible modes are available for the thermostat: Heat / Cool / Off / Auto / Energy Saving Heat / Energy Saving Cool / Em Heat. The number of allowed selections depends on the actual configuration of the thermostat. The thermostat uses "Thermostat Mode Supported" report command class to tell other devices the actually supported thermostat modes. Thermostat Operating State The thermostat can send the message containing the actual state of the HVAC equipment based on equipment state change. The thermostat provides the following operating states: • • • • • Idle - no equipment on Heating - heating equipment on Cooling - cooling equipment on Pending Heat - minimum off time applied to protect the heat pump compressor Pending Cool - minimum off time applied to protect the heat pump compressor 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. 13 69-2486—09 Installation Guide Special functions Auto Changeover (Setup Function 0300): When set to Auto, the thermostat automatically selects 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 temperature 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” is on the display.

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. 69-2486—09 14 TH8320ZW Regulatory information FCC Compliance Statement (Part 15.19) (USA only) This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1) This device may not cause harmful interference, and 2) This device must accept any interference received, including interference that may cause undesired operation. FCC Warning (Part 15.21) (USA only) Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. FCC Interference Statement (Part 15.105 (b)) (USA only) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Section 7.1.2 of RSS-GEN Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
