Tstat7 Thermostat
Description
Excellent thermostat with high accuracy temperature sensor and PI algorithm provide a comfort-
able 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 ts conventional HVAC projects.BACnet MS/TP and Modbus

Wiring Diagram
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 satised; irregularities can occur with the system.
With this easy to install and manage product, building developers/manag-
ers can deliver a system that exceeds expectations. Comfort control is made
possible at a cost savings like no other.

Tstat7 Thermostat
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, ow 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 ve 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 t for your next
installation.
Operational Functions
The buttons both the up arrow and down arrow al-
low 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 de-
gree 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 reach-
es the desired set-point (warmer/cooler) of the occupant.
1) Adjustable set-points
2) 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

or decrease the hour. Press menu key, it will switch to the minute list.
The LCD panel displays a wide variety of functions that Tstat7 thermostat can do to create a com-
fort 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.
b. Now you are in the normal state, when the menu key is pressed, the unit will switch between
schedule, clock and advanced screens. To change the unit’s ID press menu and keep pressing menu
until ‘advanced’ is displayed on the screen. Press ‘ok’ and it will display ‘sensor internal’. Repeatedly
press menu until you reach ‘net ID’. To change the net ID press the up and down arrows to increase
or decrease the value from 1 to 254. Upon choosing a desired value, leave the unit for six seconds
and the value will be stored.
