TBH300 Zigbee Energy Management Thermostat
The TBH300 is a Zigbee wireless digital thermostat with built in energy management algorithm
Features
Multi-System Compatibility
The TBH300 is compatible with most HVAC systems including 24VAC Standard gas/electric and Heat Pump System.
Powered Operation
The thermostat is powered via 24VAC power using both the C wire (24VAC common wire – typically blue) and the R wire.
Wireless Communications
The thermostat operates in a Zigbee wireless network for energy management system integration.

Setup Instructions
Follow the steps below to remove your existing thermostat and prepare for thermostats installation by identifying all wires via the procedure below.
Turn off power to the HVAC system. Usually at the HVAC system or the circuit breaker panel.
Remove cover of old thermostat to expose the wiring terminals.
Take a picture of the wiring terminals! This will help with troubleshooting later if needed.
Mark the wires attached to the terminals with the wiring labels included.
Use the terminal labels and not the wiring color to mark the wires.
Remove the old thermostat base.
Mount the thermostat base to the wall using the wall anchors and screws provided. Level as needed.
Proceed to the installation steps for your system type.
Connect the wires according to the HVAC system type as shown.
R vs RC and RH Connections:Single Transformer HVAC Systems. Typical modern central HVAC installations have a integrated heating and cooling system with a single 24VAC transformer. For these systems, there is only one 24VAC “R” wire and it can connect to either the RC or RH terminal on the thermostat. The thermostat is supplied with an RC-RH jumper installed. Do not remove the jumper for common transformer HVAC systems.
If you have additional wires for 2 stage systems (W2, Y2), proceed to Conventional 2nd Stage Installation. Otherwise, proceed to Finish Wiring.
Connect the wires according to the HVAC system type as below.

If you have additional wires for 2 stage systems (W2, Y2), proceed to Heat Pump 2nd Stage Installation.Otherwise, proceed to Finish Wiring.
Complete the wiring process by following the instructions below
Check that the wires are screwed into the terminal blocks firmly.
Gently pull on the wires to confirm the connection.
Push all the excess wiring back into the wall.
Mount the thermostat.
Proceed to Powering the Thermostat.
Install the thermostat on to the base.
Turn on power to the HVAC system/thermostat.
Proceed to the configuration step for your system type.
Configure the Fan type for your conventional system.
Gas: fan is controlled by the furnace: Congrates !! Setup Completed. Electric: fan on with heat cal and follw below steps
Go to the Menu screen by pressing and holding the FAN button for 5 seconds Press the down arrow to select the SYSTEM menu and press Select.
Set the following: SYSTEM TYPE: Set to STANDARD FAN TYPE: Set to ELECTRIC for electric heat (fan on with heat call)
If you have additional wires for 2 stage systems (W2, Y2), proceed to 2nd Stage System Setup; otherwise enroll the thermostat in your network.
Selected to configure 2nd heat/cool stage For Two Stage Heat/Cool Systems:
Go to ADVANCED SYSTEMS SETTINGS menu.From the Setup menu screen, press and hold the Fan and Down arrow buttons for 5 seconds. Use the Down arrow button to select the following:
2ND STAGE HEAT ENABLE: Enable second stage heating output If a single stage heating system, leave this set to N
If a 2 stage heating system, set to Y to enable. 2ND STAGE COOL ENABLE: Enable second stage cooling output
If a single stage cooling system, leave this set to N. If a two stage cooling system, set to Y to enable.
Configure as Heat Pump System
Go to the Menu screen by pressing and holding the FAN button for 5 seconds Press the down arrow to select the SYSTEM menu and press Select.
Set the following:
SYSTEM TYPE: Set to HEAT PUMP
CHANGE OVER: For changeover with cooling systems (Orange wire): set to WITH COOL (most common and default setting)
For changeover with heating systems (Brown wire): set to WITH HEAT
You must configure the thermostat’s changeover valve setting to work correctly with your HVAC system. Check your system information to be sure and note the color of original thermostat wire and the terminal it was connected to. No matter what the old stat connection was (O or B), connect the wire to the thermostats W2/O terminal.
If you have additional wires for 2 stage systems (W2, Y2), proceed to 2nd Stage System Setup; otherwise enroll the thermostat in your network.
Selected to configure 2nd heat/cool stage.
For Two Stage Heat/Cool Systems:
Go to ADVANCED SYSTEMS SETTINGS menu.From the Setup menu screen, press and hold the Fan and Down arrow buttons for 5 seconds. Use the Down arrow button to select the following:
2ND STAGE HEAT ENABLE: Enable second stage heating output If a single stage heating system, leave this set to N
If a 2 stage heating system, set to Y to enable. 2ND STAGE COOL ENABLE: Enable second stage cooling output
If a single stage cooling system, leave this set to N. If a two stage cooling system, set to Y to enable.
Follow the following steps to add the thermostat to a Zigbee network.
Follow the instructions provided with your system for enrolling the thermostat.
Press and hold the FAN button on the Thermostat until the screen changes to the Menu screen.
Press SELECT to enter the Setup Menu option.
Press the UP button until Start Zigbee Pairing is shown in the Status Display line.
When instructed by your system installation to add the thermostat to the network press the SELECT button to pair. Wait until SUCCESS or FAILED is shown on the status display.
Press DONE on the Thermostat to exit the Zigbee Pairing screen.
Press DONE on the Thermostat again to exit the Menu screen.
