Product data sheet TSHK 670...672: Fan-coil room-temperature controller, heating/cooling sequence How energy efficiency is improved Enables controlling of HVAC components according to needs. Room temperature can be set as the setpoint using the printed temperature scale Gradual transition from heating to cooling through sequence characteristic Variants with master switch plus slide switch for the fan Suitable for wall mounting or fitting on recessed junction boxes Electronics unit and switching relay Setpoint adjuster with mechanical min. and max. limitation of the setting range Quasi-continuous temperature control Two-point pulsed activation Individual unitary temperature control in residential and business rooms for activating e.g. electric heating systems, thermal actuators, or fans or cooling units in air-conditioning systems. Technical data Power supply Power supply Parameters Setting range Proportional band Sequence dead zone Shortest switching interval Time constant in still air Dead time in still air Time constant in moving air (0.2 m/s) 15 min Dead time in moving air (0.2 m/s) Admissible ambient temperature Operating mode Ambient conditions Construction Housing Housing material Fire-retardant thermoplastic (fire classification UL94 HB) Black thermoplastic with NTC sensor Cable inlet Screw terminals Standards and directives Type of protection Energy class Protection class The device is pulsed electronically. When the temperature increases, the control factor is reduced to 0 on the “Heating” output and increased to E = 1 on the “Cooling” output. A small temperature variation of ±0.1...0.5 K occurs as a result of pulsing, depending on the time constant of the room Right of amendment reserved

Product data sheet Overview of types Type Mains switch ON/OFF Accessories Type Pure white intermediate cover plate, suitable for various recessed junction boxes Description of operation The room temperature is measured by an internal NTC temperature sensor and compared with the setpoint applied. Depending on the temperature deviation, an electrical switching relay is activated. When the setpoint is reached, the switch moves to the middle position “Off”. The operating points of the controller are determined by the setpoint, the dead zone and the proportional band. Intended use This product...
