For ideal mounting preferably place in a clean and dry environment 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. -3- Tstat Series 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. -4- Tstat Series 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 terminal 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. 1, 3, 4, 6 Analog/Digital Inputs Temp Sensors Filter Switch Occupancy Sensor Fan Status Freeze Protection Power Meters BTU Meters 7, 9 Analog/Digital Outputs Modulating Valves Modulating Dampers 2, 5, 8, 10, 12 Ground Connections 11 Power 12-24V AC/DC 13 Common 14, 15, 16, 17, 18 Outputs 24VAC 19, 20 Network Communications -5- Tstat Series 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 before 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 plastic 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. -6- Tstat Series 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. Wiring/Equipment 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. -7- Tstat Series Operational Functions -8- Tstat Series Operation Item Description Actual Temperature Display The thermostat displays the current temperature as sensed by the internal temperature sensor. The current Heat or Cool setpoint is displayed. The setpoint may Setpoint Display be set by using the Modbus system or by pressing the Up/Down buttons. Setpoint Up/Down 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. Day/Night Settings Indicates the occupancy status during the day(sun icon) or night(moon icon) and man in(house) or out while occupied or unOccupancy Settings 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...)
