aution
s
!
We highly recommend that this installation procedure is performed by a trained HVAC
technician.
Read the enclosed instructions carefully before installing your new ZTS-500US. Pay close
attention to all warnings and notes and carefully follow the installation steps in the order
they are presented to save time and minimize the risk of damaging the thermostat or the
system it controls.
Before disconnecting wires from the existing thermostat, label the wires with the terminal
markings from the old thermostat and record them. Take a picture of the old wiring as it will
be very helpful with troubleshooting in case you need to reinstall the old unit.
Turn off electronic devices (e.g. heater, cooler) which will be connected and the electric
source before installation and maintenance.
Do not use metal conduits or cables provided with a metal sheath.
Adding fuses or protective device in the line circuit is recommended.
Battery safety!
Use new batteries of the recommended type and size only.
Never mix used and new batteries together.
To avoid chemical leaks, remove batteries from the ZTS-500US if you do not intend to use the
unit for an extended period of time.
Dispose of used batteries properly; do not burn or bury them.
Read following scenarios carefully before you start as it matters to the battery life under Z-Wave
operation:
Installation Location
This thermostat is restricted to indoor use only. It should be mounted on an inner wall about 5ft
(1.5m) above the floor at a position where it is readily affected by changes of the general room
temperature with freely circulating air. Avoid mounting above or near hot surfaces or equipment
(e.g. TV, heater, refrigerator). Avoid mounting where it will be exposed to direct sunshine, drafts,
or in a laundry room or other enclosed space. Do not expose this unit to dripping or splashing
liquids.

Explanations of Set point, Swing, Differential and Dead band
HEAT mode: Thermostat controls the temperature according to the following diagram
Example: If Heat Set point = 70°F, Swing = 1°F, Differential = 2°F, then
=> 1st stage heater turns on when room temp is 69°F and off at 71°F.
=> 2nd stage heater turns on when room temp is 67°F and off at 70°F.
COOL mode: Thermostat controls the temperature according to the following diagram
Example: If Cool Set point = 80°F, Swing = 1°F, Differential = 2°F, then
=> 1st stage cooler turns on when room temp is 81°F and off at 79°F.
=> 2nd stage cooler turns on when room temp is 83°F and off at 80°F.
AUTO mode: Thermostat controls the temperature according to the following diagram.
Press + / - buttons to adjust the appropriate set point. It will adjust the set point that is
closer to the current room temperature.
If the current temperature is close to heat set point, then it will change the heat set point value.
If the current temperature is close to cool set point, then it will change the cool set point value.
If the difference between the two is equal, then it will change the heat set point value by default.
There is a dead band 4°F/2°C (by default) between heat set point and cool set point. If user select
heat set point is 73°F, then the minimum of cool set point will be limited to 77°F.

Glossary
Device or Node
Devices and nodes are all terms to describe an individual Z-Wave
device. These are all interchangeable when setting up your Z-Wave
network.
Inclusion Add a Z-Wave device to the network.
Exclusion Remove a Z-Wave device from the network.
Remove To take a device out of a group, scene, or association group while
that device still exists in the same Z-Wave network.
Network Wide Inclusion
(NWI)
Network Wide Inclusion (NWI) enables both end-user friendly, Plug
and Play like Z-Wave network installation as well as professional
installation scenario where the inclusion process, in terms of time,
will be reduced significantly. NWI is a feature supported by a new
frame type named Explorer which enables the Z-Wave protocol to
implement Adaptive Source Routing.
Z-Wave Network
A collection of Z-Wave devices is controlled by primary and
secondary controllers operating on the same system. A Z-Wave
network has its own unique ID code so that controllers not in the
network cannot control the system.
Primary Controller
The first controller is used to set up your devices and network.
Only the Primary Controller can be used to include or remove
devices from a network. It is recommended that you mark the
primary controller for each network for ease in modifying your
network.
FLiRS Mode
FLiRS
is
abbreviation
for
“
Frequently Listening Rou
ting Slave
”
.
FLiRS mode is targeted for battery operated applications and will
enter sleep mode frequently in order to conserve battery
consumption. The response to Z-Wave command is not as quick as
Always Listening Device. Normally there is 1-2 seconds latency.
Always Listening Mode
Always Listening mode is targeted for AC power operated
applications and it can act as a repeater, which will re-transmit the
RF signal to ensure that the signal is received by its intended
destination by routing the signal around obstacle and radio dead
spots. The response to Z-Wave command is immediate.
Association
Association is used to organize nodes in different groups allowing
the device to identify the nodes by a group identifier. The groups
can also be copied to other devices.
23
Z-Wave Setup and Operations
You may check Glossary for the definition of FLiRS mode and Always Listening Mode before select
the Z-Wave operation mode.
Select FLiRS or Always Listening Mode
ZTS-500US can be powered by 4 x AA batteries, and/or 24Vac C wire. Before inclusion procedure,
user needs to check the operation mode or the power source of ZTS-500US.
- FLiRS mode (Batt) is targeted for battery operated applications and will enter sleep mode
frequently in order to save battery life. ZTS-500US can’t act as a repeater in this mode. The
response to Z-Wave commands is not as quick as devices on Always Listening mode. Normally
there is 1-2 seconds latency on response, you should avoid sending commands to the
ZTS-500US too frequently.
If it is powered by batteries, ZTS-500US will self-configure to FLiRS mode after inclusion into a
network.
- Always Listening mode (24V) is targeted for AC power operated applications and it can act as a
repeater which will re-transmit the RF signal to ensure that the signal is received by its intended
destination by routing the signal around obstacle and radio dead spots. The response to Z-Wave
command is immediate.
If it is powered by 24Vac or 24Vac plus batteries, ZTS-500US will self-configure to Always
Listening Mode.
Important:
a) Regardless of FLiRS mode or Always Listening mode, the setup and operations are the same.
Local control can also be used while it is included into a Z-Wave network.
b) After inclusion procedure, changing between FLiRS and Always Listening mode is not allowed.
To switch modes, you must perform an exclusion procedure first.
c) If you are using battery power as the main power source or as a back-up while AC power is
down and the ZTS-500US is in Z-Wave Always Listening mode, the battery will drain very fast
(battery will only survive 3-5 days).
d) If the user performs a Reset to Factory Default Settings or Z-Wave Exclusion operation, the
ZTS-500US will retain the last selected HVAC system type.

1. It is recommended to perform the Remove/Exclude procedure before performing an
Add/Include procedure. This will ensure the ZTS-500US is not in any other Z-Wave network
which will disrupt the inclusion process.
2. If the inclusion process fails, try exclusion and/or resetting the ZTS-500US to factory default and
try inclusion again.
3. If the user navigates the menu from Brightness to the right side, the Z-Wave menu will be
skipped if the ZTS-500US is already included into the network and it will loop back to the
Standby screen by pressing the > key.

Frequently Asked Questions
Q Why won’t my ZTS-500US work with the Z-Wave devices purchased in another country?
A Due to differing regulations in different countries, Z-Wave products from different regions are
set to different frequencies. Before purchasing new devices, be sure to check if the devices are
compatible in your region.
Q Do I need an electrician to install a ZTS-500US in my home?
A It is strongly recommended that a qualified technician install this product.
Q How do I know which product is compatible with my ZTS-500US?
A The ZTS-500US is compatible with any Z-Wave controller or gateway that has the control
capability for “Thermostat” devices. All Z-Wave products are also labelled with the Z-Wave logos
shown below.
Q Can I use 2 or more ZTS-500US in my house? If so, what is the max. units?
A Yes, you can use multiple ZTS-500USs in a single home. The maximum number of units depends
on the capabilities of the gateways and controllers. For example, different gateways can support
up to 8, 16, or 32 ZTS-500US on a given network.
Q What is the recommended battery type for the ZTS-500US and what is estimated batteries
service life?
A Alkaline batteries are recommended for the ZTS-500US.
Batteries service life is very dependent on the amount of usage per day. With normal use,
approximate battery service life is 1 year while operated in FLiRS mode.
If you are using battery power as the main power source or as a back-up while AC power is down
and the ZTS-500US is in Z-Wave Always Listening mode, the battery will drain very fast (battery
will only survive 3-5 days).

Wireless Information
This device has an open-air line-of-sight transmission distance of 132 feet (40m) which complies
with the Z-Wave standards. Performance can vary depending on the amount of objects in between
Z-Wave devices such as walls and furniture. Every Z-Wave device set up in your network will act as a
signal repeater allowing devices to talk to each other and find alternate routes in the case of a
reception dead spot.
Radio frequency limitations:
1. Each wall or object (i.e.: refrigerator, bookshelf, large TV, etc) can reduce the maximum range
of 65 feet (20m) by up to 20 to 30%.
2. Plasterboard and wooden walls block less of the radio signal then concrete, brick or tile walls
which will have more of an effect on signal strength.
3. Wall mounted Z-Wave devices will also suffer a loss of range if they are housed in metal
junction boxes which could also reduce the range by up to 20 to 30%.
Maintenance
Do not expose your unit to dust, strong sunlight, humidity, high temperatures or mechanical shocks.
1. Do not use old and new batteries together as old batteries tend to leak.
2. Do not use corrosive or abrasive cleansers on your unit.
3. Keep the unit dust free by wiping it with a soft, dry cloth.
4. Do not disassemble the unit, it contains no user-serviceable parts.
