Mounting

The SZ1017a, SZ1041, SZ1051, and SZ1053 are

designed for wall mounting using two #6 sheet metal

screws, either over a horizontally installed 2" x 4" junc-

tion box, or directly to block or drywall.

For best results, the thermostat should be mounted on

an interior wall which reflects normal room environment,

at a height of approximately five feet from the floor.

Avoid areas exposed to direct sunlight, unusual heat

or cool sources, open doors and windows, unventilated

locations and hot or cold air from diffusers.

If using a remote room sensor, it should be mounted in

the manner described above. The thermostat may then

be mounted in an area which is accessible for adjusting

its settings.

Caution: Remove power from thermostat prior to

mounting.

Wiring

The SZ1017a, SZ1041, SZ1051, and SZ1053 use

standard terminal designations for wiring. See diagram

below.

REMOTE TEMPERATURE SENSOR WIRING

Use 18 AWG shielded twisted-pair grounded at the sen-

sor mounting location. Sensor wiring runs of up to 250

feet are attainable if properly shielded wire is used and

the installation environment is free of electrical noise.

Sensor wire should be kept at least five feet away from

line voltage wiring.

The SZ1017a, SZ1041, SZ1051, and SZ1053 accept

three 2-wire remote temperature sensors. Consult the

TS Series Temperature Sensor Submittal Data sheet for

a complete listing of packaging and application styles.

When using TCS/Basys Controls three-wire sensors,

use the black and red leads and either clip or twist off

the white lead. Make sure that the dip switches are set

for the sensors you are using.

POWERING THE

SZ1017a, SZ1041, SZ1051, and

SZ1053

Superstats are powered from 24 VAC +/- 20%.

If wiring for communications, dedicated power must be

used to power the Superstat. Several “S” Series ther-

mostats may be powered from the same transformer,

provided that the transformer has sufficient power.

(Superstats require 8 VA @ 24 VAC.)

Caution: Do not connect to 120 VAC. When

multiple TCS Basys Controls devices are using

a single transformer, the polarity of the power

wiring must be maintained because all TCS

devices are half-wave rectified and have com-

mon return paths.

When the Superstat is used as a stand-alone thermostat

without communications, the unit transformer may be

used to power it. To do this, install a jumper between

the “R” and “+24” terminals. The “24-” terminal must

then be connected to the common side of the unit trans-

former.

Setup

Note: If using remote sensor(s), the calibra-

tion may need to be adjusted. See “Checkout and

Troubleshooting” section.

TEMPERATURE SENSOR SELECTION

The dipswitches in the cover (shown above) must be

set when using remote room, discharge, and/or outdoor

sensors.

Use the following guide to determine the dipswitch set-

tings for your application.

Using built-in room sensor only.

(This is the default setting.)

Using built-in room sensor with

discharge air sensor only.

Using built-in room sensor with

outdoor air sensor only.

Using built-in room sensor with

both discharge and outdoor air

sensors.

Using remote room sensor only.

Using remote room sensor with

discharge air sensor only.

Using remote room sensor with

outdoor air sensor only.

Using remote room sensor with

both discharge and outdoor air

sensors.

KEYPAD ACCESS

The dipswitches in the cover (shown above connected

with ribbon cable) must be set in order to lock the user

out of programming and/or to set the clock and sched-

ule. Use the guide below to set these dipswitches for

your application. User access may also be limited with

an access code set in programming. (The fan and sys-

tem switches are enabled or disabled in programming

only, and require no dipswitch placement.)

Keypad access to both program-

ming and clock setup. (This is the

default setting.)

No keypad access to programming

or clock setup.

Keypad access to programming

only.

Keypad access to clock setup only.

Once the dipswitches have been set and you have con-

firmed that the sensors are reading correctly (and pro-

gram and clock setup are finished, if locking out access

with dipswitches), secure the cover to the base with the

two set screws located at the top right and the left side

to prevent tampering.

Programming

The SZ1017a, SZ1041, SZ1051, and SZ1053 may be

programmed through the keypad on the face, or with a

PC.

If programming with a PC, the following must be set

through the face prior to programming:

• Address (step #2)

• Baud rate (step #3)

• Temperature scale (step #4)

For more information on programming through the PC,

consult your TCS software manual.
