Patent DE-4118860-A1 (DE)
Title: Room thermostat with thermal feedback - has negative temp. coefficient resistance in series with feedback resistance to eliminate adverse effects of negative feedback
Inventor: JAKOB RAINER DIPL ING
IPC: G05D23/30
Filed: 1991-06-07
Abstract: The room thermostat has thermal feedback for controlling the input line to a heating system.
