STC-1000 Thermostat
Quick Start Guide
(Version 21.08.02GEN)
STC-1000 thermostat offers two relays to wire one
refrigerator and one heater; it will auto-switch between
the heating and cooling mode; that’s why it was taken as
“All-Purpose Temperature Controller.”
1. Wiring Diagram
This unit does not output AC electricity; hence you have
to wire all live and null wires to each port; you may use
the jumper wire conveniently.

3. Set the Aimed Temp Range
The aimed temperature range was defined
from “F1 - F2” (if lower than this, trigger heating)
to “F1 + f2” (if higher than this, trigger cooling),
hence you need to set both “F1” and “F2”.
