Introduction
Congratulations on choosing the SuperSTAT™ modulating thermostat! The SuperSTAT series of controllers are feature
rich, multifunction devices providing extensive controls across a wide range of HVAC applications.
This manual applies to Model SZ1041. It includes all the information necessary to install and wire your SuperSTAT. It
includes a breakdown of the input and output wiring for each model and each type of connection.
After installing your SuperSTAT, refer to the SZ1041 SuperSTAT Conguration Guide for instructions on conguring the
device, the communications network and other devices connected to this controller.
If you have any questions regarding your SuperSTAT, do not hesitate to contact TCS Technical Support at 800.288.9383,
ext. 2. Our Technical Support Department hours are Monday – Friday, 7:00 a.m. to 7:00 p.m. (CST).
Opening the SuperSTAT
The SuperSTAT consists of a base containing wiring terminal blocks and relays, and a front cover containing the keypad
and all other circuitry.
Mounting the SuperSTAT
Mount the base of your SuperSTAT on a vertical wall using two #6 sheet metal screws, either over a horizontally mounted
2" x 4" junction box or a 4" x 4" junction box, or directly to the wall. For best results, select an interior wall that represents
a normal room environment, at a height of about 48" from the oor. Mount the unit in a location which is accessible for
adjusting settings.
For best temperature measurement accuracy, avoid areas that are exposed to direct sunlight, unusual heating or cooling
sources, open doors and windows, unventilated locations, and hot or cold air from diffusers. If you are using a remote
room sensor, mount it in the same manner.
Powering the SuperSTAT
The SuperSTAT is powered from 24 VAC +15%/–5% and draws up to 10VA. If wiring for communications, you must use
dedicated power (transformer) to the unit. Several TCS controllers may be powered from the same transformer, provided
the transformer has sufcient power and you maintain proper polarity. While the SuperSTAT may be powered from the
HVAC unit controller, using a dedicated power source will avoid any potential ground loop issues between equipment
transformers.
When the SuperSTAT is used as a stand-alone thermostat without communications, the equipment transformer may be
used to power it. To do this, install a jumper between the “R” (Packaged Unit Terminations) and “+24” (Power) terminals.
The “–24” (Power) terminal must then be connected to the common side of the equipment transformer.

SuperSTAT Wiring Connections
The input/output terminals on the SuperSTAT utilize de-pluggable terminal blocks, with two, three, or four poles. Refer to
the diagram of the base below, which indicates which terminations are active.
NOTE: For ease of installation, you can remove the cover from the base by unplugging the ribbon connector. Plug the
connector back into its socket before final assembly.

RS-485 Port
For communication wiring, use 22AWG three-wire twisted, stranded shielded copper wire. Must run separately.

Optional: When used as a standalone thermostat with no communications, you can power the unit via the HVAC
unit's transformer. To do this, install a jumper connecting the "R" and "+24" terminals. The "–24" terminal must then be
connected to the common side of the unit transformer.

Power
Connect the power source using 18AWG two-wire twisted, stranded copper wire.
NOTE: Do not connect to 120VAC. When multiple TCS/Basys Controls devices are using a single transformer, be sure to
maintain the polarity of the power wiring. All TCS devices are half-wave rectified and have common return paths.

Analog Outputs
Connect 4 – 20mA, analog output devices using 18 – 22AWG two-wire twisted, stranded shielded or unshielded wire.
Connected actuators, motors, or drives must be powered separately from the SuperSTAT. If you desire a voltage output,
use an included 500Ω resistor.

Temperature Inputs
Connect 1000Ω PtRTD temperature sensor inputs (range of –40ºF to 160ºF) using 18AWG two-wire twisted, stranded
shielded wire, maximum 250 ft. length. Sensors can be used for remote zone temperature, return air temperature,
discharge air temperature, or outside air temperature. Sensor wires should be kept at least ve feet from live voltage
wiring.
NOTE: When using remote sensors, the unit may need to be calibrated See the SZ1041 SuperSTAT Conguration Guide
for more information.
