Z-wave® Programming and Operation
Z-Wave controllers from various manufacturers may support the Z-Wave Thermostat General V2 Device
class used by the RCS TZ43 Thermostat. The following procedure will allow the thermostat to be added
to a Z-Wave network.
General Programming Procedure (for controllers supporting the thermostat device class):
1. Set your primary controller to Include mode, to add the thermostat as a node on your network (see
your controller’s user manual for detailed instructions).
2. Navigate to the Z-Wave Install Button screen. This screen is located in the Installer Screen. To
enter this screen, go to the main menu screen and press and hold the two inner buttons
for 3 seconds until the Installer Settings screen appears. Scroll down until the Z-Wave Install
Btn menu item is selected, press the Select button.
3. Press the YES button.
Your controller will indicate the thermostat was successfully added to its network (see your controller’s
user manual for details). Also you can check if the thermostat was successfully added to the network
by checking the ZHID (Home ID) and ZNID (Node ID) located in the Thermostat Info screen.
For other specific tasks such as adding the thermostat to Scenes or Groups, or deleting the
thermostat from an existing network, use the Z-Wave Install Button procedure.
Note: Before adding the thermostat to a Z-Wave Network, check that it does not already belong to
one by viewing the Home and Zone ID’s located in the Thermostat Info screen. An unconfigured
thermostat should show zeros for both the Home and Zone IDs. Consult your controller’s user manual
for details on removing a device from a Z-Wave network.
If your controller does not support full thermostat device class functions, it may still be able to control the
NORMAL/SAVE ENERGY mode (ie. Set Back RUN/HOLD) of the thermostat through basic ON/OFF
commands similar to those used by lighting switches. By sending the basic command ON, the thermostat
will go into the NORMAL-SETBACK HOLD mode. Sending the basic command OFF, the thermostat will
go into the SAVE ENERGY-SETBACK RUN mode.
Inclusion and Exclusion
Inclusion or exclusion is started by putting the controller into add node or remove node state and
performing the General Programming Procedure outlined above. As part of the process, the thermostat
sends a node information frame at normal power. Low power inclusion or low power exclusion is not
possible.
