TSHK 621...643: Fan-coil room-temperature controller, How energy efficiency is improved Enables controlling of HVAC components according to needs. • Variable room temperature as setpoint based on printed temperature scale • Changeover from heating to cooling via switch or type of connection • ON/OFF toggle switch for mains voltage, plus other slide switches for operating mode and fan, de- • More constant room temperature due to thermal feedback • Suitable for wall mounting or fitting on recessed junction boxes • Setpoint adjuster with mechanical min. and max. limitation of the setting range • Two-point pulsed activation • Individual unitary temperature control in residential and business rooms for activating, for example, electric heating systems, thermal actuators, or fans or cooling units in air-conditioning systems. Technical data Power supply Shortest switching interval Approx. 19 min (E = 0.5) Time constant in still air 20 min Dead time in still air 2 min Time constant in moving air (0.2 m/s) 15 min Dead time in moving air (0.2 m/s) 1 min Ambient conditions Admissible ambient temperature 0...55 °C Housing material Fire-retardant thermoplastic (fire clas- Baseplate Black thermoplastic with bimetallic sensor and contact snap mechanism with permanent magnet Cable inlet At rear Screw terminals For electrical wires of up to 2.5 mm2 Protection class Energy class 1> 10% more voltage results In: P-band = approx. 4 K, switching period = 15 min, actual-value reduction = approx. 2> Devices with thermal feedback are pulsed by an in-built heating element. The control factor reduces as the tem- perature increases (i.e. the controller has proportional behaviour). A small temperature variation of±0.1...0.5 K occurs as a result of pulsing, depending on the time constant of the room WSAUTER Right of amendment reserved © 2015 Fr. Sauter AG

Product data sheet Overview of types Type Operating mode Heating only/cooling only; 2-pipe Mains switch ON/OFF Operating mode switch Accessories Type Pure white intermediate cover plate, suitable for various recessed junction boxes Description of operation A bi-metallic strip snap mechanism expands depending on the temperature and activates an electrical switch. The coupling with a permanent magnet means that even if the temperature changes are very slow, a clear contact is made. Intended use This product is only suitable for the purpose intended by the manufacturer, as described in the...
