Module User Guide

The RTZW-02 USNAP module is a plug in

module that adds Z-Wave® functionality to a

CT-Series Thermostat [CT= Communicating

Thermostat].

A CT-Series Thermostat with an RTZW-

02 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-02 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,

PG 2

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-02 USNAP module is designed to be inserted into the right side

USNAP slot in any CT-Series Thermostat. (Follow the instructions that come

with your CT-Series Thermostat and install it to your HVAC system before

installing the RTZW-02 USNAP module.)

Note: Some

models of the

CT-Series are

capable of

operating in

battery only

mode (i.e. without

C-wire from

HVAC system),

yet some other models of the CT-Series (like the CT-80) are only capable of working

in your HVAC system with the C-wire present.

The RTZW-02 USNAP 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 model CT-Thermostat you have, and

how your CT-Thermostat is powered will determine which functionality the

RTZW-02 module will have when added to a Z-Wave® network.

Getting Started

Examine your CT-Thermostat and identify an empty USNAP slot (refer to your

CT-Thermostat instruction manual for details).

1) Power OFF the thermostat by removing batteries and disconnecting the C

wire.

2) Insert the RTZW-02 module into the CT-Thermostat Radio Slot [ right side] with the

label on the RTZW-02 facing the wall behind the thermostat. The RTZW-02 module

should slide in and engage with no visible protrusion from the thermostat.

3) Power up the thermostat by re-installing the batteries and re-connecting the

C wire.

4) Press the reset button on your CT (see thermostat documentation) and reset

the CT by pressing the reset button for 1 second.

PG 3

PG 4

During reset you should see the “radio tower” icon appear on your CT along

with the slot number “2” indicating that the CT Thermostat is initializing the RTZW-02

USNAP module. When this ﬁnishes (about 15 seconds), your CT Thermostat

will be ready to join and be controlled by a Z-Wave® network.

Join or Un-Join Network

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/Touch the Mate Button. This will bring you to the network joining

screen.

Mate button: On touch screen units the MATE button is on the MENU

screen. On basic LCD thermostat’s the mate button is under the top

cover at the right side.

3) If you only have 1 USNAP 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 an

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.

4) 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 icon LINK will appear under the radio tower.

Similarly, when you are trying to leave a network, the icon 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 Z-Wave® 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

c) Read the current temperature

PG 6PG 6

d) Set/Read the indicator

e) Set/Read the Fan mode

f) Set/Read the clock (on certain CT models only)

g) Set/Read the user display area (on certain CT models only)

Battery Power

When your thermostat is running on battery power, the Z-Wave® radio will

turn off to help conserve battery life. The RTZW-02 Z-Wave® radio module

supports Z-Wave® beaming, which allows other devices in the network to wake

up the RTZW-02 and accept commands, and then go back to sleep.

C-Wire Power

When your thermostat is running on C-Wire power, the Z-Wave® radio will stay

on and actively help in routing messages within the Z-Wave® network.

Simple Mode/Normal Mode

The CT-Thermostat offers two modes of operation, Normal Mode and Simple mode.

NOTE: the SAVE ENERGY ffunction is disabled with Z-Wave operation.

Normal mode is intended for use as a stand alone programmable thermostat.

In Normal mode the user can program the thermostat to change temperatures

at various points throughout the day. Simple mode is intended for use with

a larger control system - like an alarm system or home automation system.

Simple mode is meant to run a single temperature constantly. This temperature

can be set locally on the thermostat, or remotely using a Z-Wave® USNAP

module. To enter simple mode: Press and hold the PROG button for 12

seconds. To leave simple mode, press and hold the PROG button for 12

Advanced Z-Wave® Information

The RTZW-02 supports compliant mapping of the Z-Wave® BASIC_

COMMAND_CLASS to the CT thermostat “Energy Saving” and “Comfort

Mode” as follows:

Basic Set (Value = 0x00) = Set Energy Saving Mode

Basic Set (Value = 0x01-0x63 & 0xFF) = Set Comfort Mode

Energy Savings applies a 4

F setback to the existing set point temperature to

comply with EPA recommendations for energy savings.

Power Requirements

Your thermostat ZWave module has been designed to work on either battery power

or power from your furnace. If your HVAC system has a power wire (also known as

a “C” or “COMMON” wire) and the thermostat is connected to the “C” wire, power

will come from the furnace unless there is no power available and then power will

come from the batteries. So, if you do not have a “C” wire, ask your HVAC techni-

cian to install one the next time you have your furnace upgraded or serviced. This

will allow you to achieve optimal performance and convenience.

Remember to replace the three (3) AA batteries in your thermostat with new alkaline

batteries whenever the low battery indicator comes on. If you leave your house for

two weeks or more, it is essential for you to replace the batteries. If your thermo-

stat is not powered by your HVAC system and has to rely entirely on batteries,

the HVAC system will stop working when the batteries die.
