Radio Thermostat Z-Wave U-Snap Module
RTZW-01 User's Manual CTxx series
The RTZW-01 U-Snap module is a plug in module that adds ZWave functionality to a
CTxx series thermostat.
A CTxx series thermostat with an RTZW-01 module is compatible with a broad range
of Z-Wave® certified devices from other manufacturers and can be controlled
wirelessly with Z-Wave controllers supporting the Thermostat General V2 Device
Class. Please consult the user manual and your controller supplier for more details.
The RTZW-01 provides two-way communication as part of a Z-Wave® network.
When it receives commands from Controller device, it sends back confirmation that
the command was received and implemented. Each module in a Z-Wave network
communicates with every other module, acting as a “repeater” and routing your
commands to their destination by the most reliable pathway. When Z-Wave devices
regardless of manufacturer) are installed throughout the house, signals are
automatically routed around obstacles or dead spots, strengthening the network as
more devices are added.
The Basics:
The RTZW-01 U-snap module is designed to be inserted into an empty U-snap
receptacle in any CTxx series thermostat. (Follow the instructions that come with
your CTxx series thermostat and install it to your HVAC system before installing the
RTZW-01 U-snap module.)
Note: Some models of the CTxx series are capable of operating in battery only mode
(i.e. without C-wire from HVAC system), yet some other models of the CTxx series
(like the CT-80) are only capable of working in your HVAC system with the C-wire
present.
The RTZW-01 U-Snap module is designed to work with either constant present power
in the thermostat (ie C-wire), or it can run only on batteries when no C-wire is
present. Depending on which module CTxx you have, and how your CTxx
thermostat is powered will determine which functionality the RTZW-01 module will
have when added to a Z-wave network.
Getting Started:
Examine your CTxx thermostat and identify an empty U-Snap receptacle. (refer to
your CTxx instruction manual for details).
Insert the RTZW-01 module into the CTxx receptacle with the label on the RTZW-01
facing the wall behind the CTxx thermostat.
The RTZW-01 module should slide in and engage with no visible protrusion from the
CTxx thermostat.
Once the module is seated, locate the reset button on your CTxx (see thermostat
documentation) and reset the CTxx by pressing the reset button for 1 second.
During reset you should see a “radio tower” icon appear on your CTxx along with
some beeps indicating that the CTxx thermostat is initializing the RTZW-01 U-Snap
module. When the beeping finishes (about 10 seconds), your CTxx thermostat will
be ready to join and be controlled by a Z-wave network.
Network Inclusion/Exclusion:
1.Set your primary controller to INCLUDE mode, to add the thermostat as a node on
your network (see your specific controller’s User Manual for detailed instructions.)
2. Press and release the MENU button on the thermostat.
3, Press the Mate Button - This will bring you to the network joining screen .
4. If you only have 1 U-SNAP module inserted in the thermostat you will see a r1 or
r2 to indicate that the radio is in slot 1 or slot 2. If you have multiple radios you
can select which radio you want to join the network by selecting either r1 or r2
from the top left hand corner of the screen. When you have selected a radio, the
large r1 or r2 will appear in the center of the screen.
5. When the radio is selected and the large r1 or r2 is on the center of the screen,
press the mate button, this will initiate the mating process. When a device has
joined a network the word «LINK» will appear under the radio tower. Similarly,
when you are trying to leave a network, the word «LINK» will disappear when the
node has successfully left the network.
Your controller will indicate the thermostat was successfully added to its network
(see your specific controller’s User Manual for details.)
For other controller specific tasks such as adding the thermostat to Scenes or
Groups, or deleting the thermostat as a node, use the mate button to activate the ZWave® signal.
Operation:
See your specific controller’s User Manual for detailed instructions on operating your
thermostat. If your controller supports full thermostat device class functions then the
following remote features are available:
a) Up and Down Temperature Control.
b) Change between HEAT and COOL modes.
