Technical Data
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.
Tight control of 0.5°C provides comfortable indoor environment with its built in sensor, which is located in
the controller and it will not be affected by the temperature of the wall on which it is mounted on.It is possible to
connect an external sensor for monitoring the temperature of different locations.
With a high impact plastic enclosure will provide durability in any commercial environment. The side panel
provides all the control buttons need to enable and create set-points for desired temperature settings and fan
settings. Changes in temperature can be monitored continuously at the shortest time interval possible.

Mounting Installations
TSTAT7 is specifically a wall mounted indoor use only thermostat that can be strategically placed
anywhere because of its size and weight. For ideal mounting preferably place in a clean and dry envi-
ronment and away from any areas that might affect the temperature reading such as a window.
There are two parts to the TSTAT7 product, one being the back plate that gets mounted onto the
desired surface and the other being the front cover.

1)Removing the TSTAT7 back plate from the front cover you must do the following steps:
a)Unfasten the screw that is located at the bottom of the back plate that holds the back plate
with the front cover.
b)Hold the back plate and gentle remove it from the front cover, allowing for the top of the
backplate to be dislodged from the plastic clippings that are located at the top.Pushing the plastic
clippings in while detaching may allow for a smoother process.

c)It should be free from connection to the terminal blocks but if not gently try to push in an upward
motion on the bottom of the front cover.
d)Now there should be two parts in your possession. You can lay the front enclosure panel down;
you will not need it until re-attaching it to the back enclosure panel once it is mounted. Place in a safe
area where neither side of the panel can be damaged. (Side note: When picking front panel back up
make sure to check that all components inside were not damaged)
2)Mounting the TSTAT7 back plate securely to desired surface:
a)Have the removed back plate in hand; knock out the center of the back plate. You can use the
butt end of the screw driver to do this. The back end once knocked out has no use anymore and can
be thrown out.
b)Insert the wires through the center of the back plate that has just been removed. If necessary,
use a wire stripper to remove about 1/4 of an inch of the plastic insulation from the ends of the wire.
c)Attach the wires to the correct screw terminals that are listed on the back plate. Below is a termi-
nal block that can aid in the connection of the wires. Also you can consult the wiring diagram to make
sure that everything is connected properly, so there are no problems after the front panel enclosure is
put on.

d)Fasten the screws that mount the back plate to the area you want to mount the thermostat
on. Make sure that the thermostat is level and flush with the wall so no wires are stuck behind be-
fore screwing into the wall. The thermostat is a light weight product but for best installation preferably
screw the back plate into a stud behind the drywall.
e)Put the TSTAT7 directly over the mounting connectors and begin to push gently. The two plas-
tic clippings located at the top of the front cover should fit together smoothly with the plastic slots on
the back plate. There might be some playing around with getting both slots to clip in nicely.

f)Now the front cover and the back plate should be firmly placed together with terminal
connections and plastic clippings in place. Re-fasten the screw that was taken out originally;securing
the back plate to the front cover.
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
or even fatal harm.

Operation
Item Description
Actual Temperature Display The thermostat displays the current temperature as sensed by the
internal temperature sensor.
Setpoint Display
Setpoint Up/Down
The current Heat or Cool setpoint is displayed. The setpoint may
be set by using the Modbus system or by pressing the Up/Down
buttons.
In Heat Mode, the Up/Down Buttons change the Heat setpoint.
In Cool Mode, they change the cooling setpoint.
In Auto, they change the last setpoint entered heating or cooling.

night(moon icon) and man in(house) or out while occupied or un-
occupied described as follows: In occupied mode,it shows the sun
and the man in.In unoccupied mode,it shows the moon and the
man out. In low occupancy, it shows the moon and the man in.
Clock Display The current time is displayed in the second half of the screen.
Day of the week Indicates the current day by showing the following terms:
Mon,Tue,Wed,Thu,Fri,Sat,Sun
2 x 8 display for Setup & Status The 2 by 8 characters display shows all the informations,status
& setup concerning sensor(s),clock and all the advanced menu
keys(fan,occupancy schedule,units,etc...)
Temperature Units Indicates Celsius(°C) or Farenheit(°F) according to your prefer-
ence
Relative Humidity The thermostat displays the current relative humidity as sensed by
the internal humidity sensor(Optional)
Heat/Cool/Fan Icons Indicates the current status according to the setpoint and the cur-
rent conditions in the room. It shows a flame when heat is on,a
snowflake when cooling and a fan when the fan is running.
Mode Buttons Used to select the Mode needed(Cool-Heat-Auto-Off)
Menu Button Enter the main menu and program all the settings.
-Sensor(internal + 4 inputs)
-Clock(date & time)
-Advanced Menu(Scheduling,time format,temperature unit,Rh,fan)
OK Button Used to enter in the main menu and select one of the command.
Override Button This will cancel the unoccupied setting and start a timer that can
be adjusted through Modbus. This button is used in case of come
back during unoccupied mode.

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 LED panel. To increase the set-point tempera-
ture 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 LED panel will display the current set-point, until the tempera-
ture in the room reaches the desired set-point (warmer/cooler) of the occupant.
