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.
