POWERING THE SUPERSTAT
Superstats are powered from 24 VAC +/- 20%.
If wiring for communications, dedicated power must be
used to power the Superstat. Several “S” Series thermo-
stats may be powered from the same transformer, provid-
ed 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 common return paths.
When the Superstat is used as a stand-alone or wireless
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
transformer.
Wiring
The SZ1022, SZ1031, and SZ1035 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 SZ1022 accepts two 2-wire remote sensors and the
SZ1031 and the SZ1035 accept three. 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.
