TEMPERATURE CONTROL SYSTEM

Temperature control system (1) for a room. Two heat exchangers (4-6), each having a control valve (20-21), supply and return ports connected to a fluid supply system (7, 8) supplying a heat carrying fluid, sensors (12-18; 23-25) detecting a physical characteristic of the heat carrying fluid at each...

Beschreibung
Zusammenfassung:	Temperature control system (1) for a room. Two heat exchangers (4-6), each having a control valve (20-21), supply and return ports connected to a fluid supply system (7, 8) supplying a heat carrying fluid, sensors (12-18; 23-25) detecting a physical characteristic of the heat carrying fluid at each heat exchanger and an additional physical characteristic, processing means comprise diagnostic means detecting a kind of a malfunction of the supply when at least one of the following conditions are fulfilled: a) a difference between an inlet temperature and an outlet temperature is smaller than a predetermined value and a difference between the room temperature and a desired room temperature is larger than a predetermined value, b) control valves are open and inlet temperature is smaller than an expected temperature, c) a difference between an inlet temperature and an average room temperature is smaller than a predetermined value.
