TMST-2B-ZBS Thermostat
Introduction
TMST-2B-ZBS is a battery powered ZigBee Thermostat. It is designed to be incorporated into household heating and
cooling system for home environment control. The Thermostat can be operated manually using the LCD screen and
buttons, or accessed remotely via ZigBee network. It feature Cooling, Heating, Auto modes with temperature set point and
automatic schedule for you to control your home environment easily.
The Thermostat utilizes ZigBee technology for wireless signal transmission. ZigBee is a wireless communication protocol
that is reliable and has low power consumption and high transmission efficiency. Based on the IEEE802.15.4 standard,
ZigBee allows a large amount of devices to be included in a network and coordinated for data exchange and signal
transmission
The Thermostat serves as an end device in the ZigBee network. It can be included in the ZigBee network to transmit signal
upon activation, but cannot permit any other ZigBee device to join the network through the Thermostat.

Cool, Heat and Auto Mode
Cool Mode: Thermostat will activate cooling when temperature rises above Cool setpoint to make sure
temperature does not go over the setpoint.
Heat Mode: Thermostat will activate heating when temperature drops below Heat setpoint to make sure
temperature does not go below the setpoint.
Auto Mode: Set both Heat and Cool setpoints for auto mode. Thermostat will control the temperature so that it
does not exceed the Heat and Cool setpoint range.
Press any of the UP, Down or Mode button, the Thermostat will display current mode, temperature set point 
and light up LCD backlight for 4 seconds.
Press the Mode button again during this period to set Thermostat mode between Cool, Heat and Auto. 
Press the Up or Down button to select temperature set point.
Heat setpoint range: 9°C ~ 30°C.
Cool setpoint range: 11°C ~ 32°C.
The Cool set point must be at least 2℃higher then Heat set point.
Press the Mode button The Thermostat will exit setting screen and apply the new setting after 4 seconds of 
inactivity.

Away Mode 
Away Mode is used to monitor house temperature when it is unoccupied. It should be activated manually when
user is leaving the house. Press the Away button to put Thermostat into Away mode.
To program Away Mode setting, press and hold Mode button for 3 seconds. You will first program Away Cool 
set point, press Mode button after finish setting to program Away Heat set point, the Cool set point must be at
least 2℃higher then Heat set point. Press Mode button again to program Fan setting when done.
Fan Setting 
When in Fan setting, press UP or Down button to select fan option between Always on or Auto mode. 
Always On ( icon steady on) – The fan is always turned on except under Off Mode
Auto mode ( icon flash) – The fan will be turned on according to Away, Cool and Heat mode setting.
Off Mode 
The Thermostat can be put into Off mode by pressing and holding the Away button for 3 seconds. When under Off
mode, the Thermostat stop all function and only display current time.
Time / Temperature Display / HVAC Type Setting: 
Press and hold the Mode button for 10 seconds to enter setting mode. The time on LCD display will begin to flash:
Use the Up and Down buttons to select time and Mode button to proceed to next option. Available options 
include:
1. Weekday
2. Hour
3. Minute,
4. AM/PM or 24-hour format display. (You can only change the time display format when the time is set to
between 1:01~12:59)
5. Celsius or Fahrenheit display
6. HVAC type: Type 1 = Gas/Electric, Type 2 = Heat Pump(O), Type 3 = Heat Pump(B).
Factory Default HVAC Type = 1 Gas/Electric
 HVAC Type
According to the HVAC system in the home environment, select the HVAC type in Thermostat setting.
Type 1: General Gas/Electric HVAC system
Type 2: HVAC system with Reversing Valve which operates during Cooling (Heat Pump “O”)
Type 3: HVAC system with Reversing Valve which operates during Heating (Heat Pump “B”)
 Remote Control
After the Thermostat joins a ZigBee network, you can control the Thermostat via ZigBee network coordinator or
gateway. Please refer to your ZigBee coordinator/gateway manual for more information.
The following functions are only available for setting via ZigBee coordinator and gateway:
Schedule: 
You can only program Schedule configuration via ZigBee network coordinator/gateway.
Schedule Setting: Up to 5 schedules can be programmed for every weekday with Mode, Setpoint and Start time.
Schedule Control:
Normal - The Thermostat will execute programmed schedule setting accordingly.
Hold – The Thermostat will bypass currently timed schedule and perform the next schedule when it begins
No Schedule – The Thermostat will not execute any set schedule until it is set to Normal again.
 Temperature Detection
The Thermostat has built-in temperature sensors and will display the temperature reading on the LCD display
The Thermostat will transmit temperature signals regularly according to setting. The factory default interval is 10
minutes.
When the temperature changes by +/- 2°C, the Thermostat will also transmit a signal.
You can also press the ZigBee Network Button once to transmit a temperature signal manually.
Supervision
The Thermostat will transmit a supervision signal every 10 minutes along with the temperature, current mode and set
point information to report its condition regularly.

ZigBee Network Setup
 ZigBee Device Guideline
ZigBee is a wireless communication protocol that is reliable and has low power consumption and high transmission
efficiency. Based on IEEE802.15.4 standard, ZigBee allows a large amount of devices to be included in a network
and coordinated for data exchange and signal transmission.
Due to the fundamental structure of ZigBee network, ZigBee device will actively seek and join network after powering
on. Since performing a task in connecting network may consume some power, it is required to follow the instructions to
avoid draining battery of a ZigBee device
- Ensure your ZigBee network router or coordinator is powered on before inserting battery into the ZigBee device.
- Ensure the ZigBee network router or coordinator is powered on and within range while a ZigBee device is in use.
- Do not remove a ZigBee device from the ZigBee network router or coordinator without removing the battery from a
ZigBee device.
 Joining the ZigBee Network
As a ZigBee device, the Thermostat needs to join a ZigBee network to for user to control it remotely. Please follow the
steps bellow to join the Thermostat into the ZigBee network.
1. Remove the Thermostat back cover and insert 2 AAAlkaline batteries to power up the Thermostat.
2. Press and hold the ZigBee network button for 10 seconds then release to join ZigBee network. Please make sure
the permit-join feature on the router or coordinator of your ZigBee network is enabled.
3. Wait for several seconds for the Thermostat to join ZigBee network, if the Thermostat successfully joins a network,
the ZigBee connection icon will appear on LCD display.
4. After joining the ZigBee network, the Thermostat will be registered in the security system in the network
automatically. Please check the security system control panel or CIE (Control and Indicating Equipment) to confirm
if joining and registration is successful.
5. After joining the ZigBee network, if the Thermostat loses connection to current ZigBee network, the ZigBee
connection icon will disappear after 10 minutes. Please check the ZigBee network condition and Thermostat signal
range to correct the situation.
Removing Device from ZigBee Network (Factory Reset)
To remove the Thermostat from current ZigBee network, the Thermostat must be put to Factory Reset to complete
device removal. Factory Reset function will clear the Thermostat of its stored setting information and prompt the
device to search for new ZigBee network.
Before removing device, make sure the Thermostat is within current ZigBee network signal range
1. Press and hold the function button for 10 seconds, then release the button to reset Thermostat.
2. Upon reset, the Thermostat will clear current ZigBee network setting and transmit signal to ZigBee coordinator to
remove itself from current ZigBee network. It will then actively search for available ZigBee network again and join
the network automatically.
Thermostat Mode Setting Reset
The Thermostat mode setting can be reset to factory default by following instruction below:.
1. Remove batteries to power down the Thermostat.
2. Press and hold both Up and Down buttons and insert batteries when holding down the button.
3. Release the buttons after the Thermostat is powered up. The Thermostat setting has been restored to factory
default:
Mode: Heat
Heat set point: 20℃
Cool set point: 26℃
Away mode heat set point: 10℃
Away mode cool set point: 30℃
Time: 00:00
Time display: 24-hour format
