No, your first assumption was correct. You plug your heat pad into the thermostat, the thermostat plugs into the wall. You adjust the temp on the thermostat and it regulates the power output to the heat pad... The probe from the thermostat reports the current temp back to the Tstat so it knows if it needs to output more or less and adjusts accordingly.
