I cannot say exactly which HVAC or thermostat wires you connect this to.
The wire does not need power, or it can have 12-24 AC/DC or 120, 208, 240, 277 volt AC.
You can simply cut a control wire, and insert ST01 as shown.
Timer red wire is capped.
If you connect timer red and blue wires, then timer programming is reversed...
THIS means what?
ST01 is programmable, or dusk-dawn timer.
Choose up to 6 on-off programs, or choose dusk-dawn. (either-or, not both)
Dusk-dawn means timer is ON at night.
Connect red-blue wires, then timer is ON during day.
Use ST01 without any voltage, or with any voltage
