Wiring
The SZ1061 and SZ1062 use standard terminal desig-
nations for wiring. See diagram below.
REMOTE SENSOR WIRING
The SZ1061 accepts one 1000 ohm two-wire platinum
sensor and the SZ1062 accepts two. Use TS1009,
TS1002 with TQ Series Immersion wells or TS1005 for
water temperature sensing.
When using TCS/Basys Controls three-wire sensors,
use the black and red leads, and either clip or twist off
the white lead. The wiring length should not exceed
250 ft.
POWERING THE SZ1061 &SZ1062
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, pro-
vided 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 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 transform-
er.
