ZTS-100 Z-Thermostat
Introduction
Welcome to the Z-Wave world of home automation, your ZTS-100 Z-Thermostat (Figure 1) is a
comfort control master that allow to control your room temperature with programmable time
schedule WAKE, AWAY, HOME and SLEEP event which can maximize energy conservation and
comfort while minimizing the effort required to maintain the appropriate temperature in your home
whether you are at home or away.
Also, it is allow to control / check your room temperature by the smart phone or PC while you are at
office, home anywhere or around the world which can go through the Z-Wave gateway control.
ZTS-100 also supports batteries operation that can provide flexibility if there is out of 24VAC power
line.

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 Delete 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.
Z-Wave Network
A collection of Z-Wave devices 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 used to set up your devices and network. Only
the Primary Controller can be used to include or delete devices
from a network. It is recommended that you mark the primary
controller for each network for ease in modifying your network.
Secondary Controller
A controller containing network information about other devices
within the network and is used for controlling devices. Secondary
controllers are created from the Primary Controller and cannot
include or delete devices to the network.
Inclusion Controller
A controller containing network information about other devices
within the network and is used for controlling devices. Inclusion
controllers are created from the Primary Controller in a SIS enabled
Z-Wave network. Inclusion Controller has the ability to add and
remove devices from the network.
Scene
A collection of Z-Wave devices configured to turn to a specific
level, setting, mode, or perform an operation. Scenes are usually
activated by a controller, timed event, or specific conditions.

Physical Installation and Wiring
LCAUTION
−Read the enclosed instructions carefully before installing your new Z-Thermostat. 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.
−Turn off ZTS-100 and the electronic devices (e.g. heater, cooler) which will be connected and
the electric source before installation and maintenance. It is highly recommended that the
installation procedure is processed by trained personnel.
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-100 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.
Installation Location:
The Thermostat is restricted to be used in indoor only. It should be mounted on an inner wall about
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.
Wiring:
zBe sure the operation mode is OFF and Fan selection is Fan Auto
zWire the proper cables at the terminal block according to the circuit diagram
zAfterward, push all cables back into the wall
zDo not use metal conduit or of cable provided with a metal sheath
zRecommends adding fuse or protective device in the line circuit

Important!
The ZTS-100 can be powered by alkaline batteries AA x 4pcs or 24Vac.
Connect the “24VAC Common” (typically the Blue wire/terminal) and “24VAC Return” (typically
the Red wire/terminal) from the HVAC system to the ZTS-100 HVAC System terminal block “C”
and “RH” or “RC” terminals (the RH and RC terminals are default tied together).
Common or Split Transformer Systems:
Most HVAC systems have a common heating and cooling transformer. A wire is connected to tie the
RH and RC inputs together for this configuration. If you have a system with separate heating and
cooling transformers, you will need to disconnect the RH and RC wire.
When wiring split systems, wire the heating systems “24VAC Return” (red wire) to the ZTS-100
“RH” terminal, and wire the cooling systems “24VAC Return” to the ZTS-100 “RC” terminal. Also
wire the cooling systems “24VAC Common” to the ZTS-100 “C” terminals.
Note: Do not split RC/RH for Heat Pump systems!

3. Check the polarity of the batteries and the "+/-" marks inside the battery compartment
4. Connect 24Vac common at C terminal if using 24Vac power
5. Place the cables at the hole near the terminal block
6. Insert 2 pieces of wall anchors into the holes of the wall
7. Fasten the thermostat with 2 pieces of long screws through the 2 mounting holes (Figure 6)
8. Install the top housing by hooking the bottom (Figure 6)
