Bravo Tstat 7 Thermostat
Description
Excellent thermostat with high accuracy temperature sensor and PI algorithm provide a comfortable indoor environment with its built in sensor, which is located in the controller and it will not be affected by the temperature off the wall on which it is mounted on. It is possible to connect an external sensor for monitoring the temperature of different locations. This full-featured CPU based thermostat is designed for small cooling and heating air handling systems in residential and commercial facilities. The unit provides features which eclipse standard mechanical thermostats at a price that fits conventional HVAC projects.BACnet MS/TP and Modbus RTU protocols over RS485

Typical Wire Routing
For proper safety all wiring and controllers should be installed separately to avoid accidently contact with one another. Make sure to keep wiring and equipment/controllers six feet from power distribution, motors, etc. If these conditions are not satisfied; irregularities can occur with the system.
With this easy to install and manage product, building developers/managers can deliver a system that exceeds expectations. Comfort control is made possible at a cost savings like no other
Wiring Diagram
The wiring diagram above outlines the basic functions the TSTAT7 thermostat can do for you. With four analog/digital inputs you can plug in occupancy sensors, flow sensors, fan status, freeze protection, power meters and BTU meters just to name a few. There are 2 analog outputs that can be used for modulating valves and modulating dampers. It comes equipped with a RS485 network that can be connected to a controller like a boiler as illustrated above. On the other side we have five relay output capabilities which can be used for air handler units, fan coil units, heat pumps and many other different types of hydronic applications. The TSTAT7 thermostat is compatible with any desire you need and the perfect fit for your next installation.
Operational Functions
Adjustable set-points
The buttons both the up arrow and down arrow allow the consumer to increase or decrease the desired set-point they wish to have. To adjust the set-point on the room sensor can only be done when the occupied symbol is being displayed on the LCD display. To increase the set-point temperature by a degree simply hit the up arrow button. To decrease the set-point temperature by a degree simply hit the down arrow button and continue either step until desired set-point is achieved. After the set-point is increased or decreased the LCD screen will display the current set-point, until the temperature in the room reaches the desired set-point (warmer/cooler) of the occupant.
There are six buttons that operate the Tstat7:
| Buttons | Functions | |
 |
Top button (right side) | Increases setpoint |
 |
Second button from top (right side) | Decreases setpoint |
 |
FAN Mode: Middle button (right side) | Adjusts manually/automatically the fan speed to satisfy cool air temperature |
 |
Main MENU: Second button from bottom (right side) | Optimizes the settings of heating/cooling, clock, schedule, etc |
 |
Ok: First button from bottom (right side) | To save or enter a setting in the main menu |
 |
Override switch
unmarked (center of front cover) |
For new occupancy adjustments |
- Normal state
- When press mode key, it will be switched between fan mode and heat\cool. When press up and down keys, it will go into the fan mode list or heat cool list
- Now you are in the normal state, when press menu key, it will be switched between schedule, clock, advanced. When it comes to schedule, press OK, go into the day set list. Press menu key go into the occupied\unoccupied time set and press up\down arrow key, will increase or decrease the hour.

Upon choosing a desired value, leave the unit for six seconds and the value will be stored
- LCD Display Features
- The LCD panel displays a wide variety of functions that Tstat7 thermostat can do to create a comfort level like no other. Be able to automatically adjust the heat, cool, and fan modes to which ever temperature you desire; day or night. You can also program the thermostat to operate at a lower level when the room or building is unoccupied, saving energy and costs on your electric bill, what’s more, the earth will become more and more beautiful and ecological
Set net ID, Baudrate and protocol through main menu button
- Press the menu several times to display advanced and then press “OK
- Press menu again(Press multiple times until the net ID option is found, Change by up and down key)
- Press menu again(Press multiple times until the baudrate option is found, Change by up and down key)
- Press menu again (press multiple times until the protocol option is found, press up and down to select Bacnet or Modbus)
Installation Mounting
- Unfasten the screw located at the base and lift off the front panel of the enclosure.
- Wall mount: Fasten the screws on the back panel to the wall, and re-attach the front panel to the now mounted panel. Refasten the screw at the base connecting both panels.
- Standard ‘11-10’ electrical box: Fasten the screws on the back panel to the electrical box, and re-attach the front panel to the now mounted panel. Refasten the screw at the base connecting both panels.
