LK Room thermostat type S2 EXT

Description

Room thermostat type S2 EXT, 24V suitable for controlling underfloor heating with touch display. Only suitable for heating. For stand alone use or for connection to a Stuhl SAM 8.1 / 2 terminal strip. Comes standard with external sensor

This 24V room thermostat is an electric room thermostat with a triac output, specially produced for underfloor heating systems.
The room thermostat is used in conjunction with Normally Closed (NC) electrothermal actuators. To achieve maximum energy efficiency, the thermostat uses self-modulating technology by sending a signal to the actuator. The self-modulating technology adjusts the output signal / output of the underfloor heating to the set temperature. As soon as the ambient temperature approaches the set temperature, the heating output is gradually decreased to prevent overheating. The room thermostat is also used in public environments, where the temperature settings are locked by pressing a button combination.

Specific advantages:
• Self-modulating technology via signal waves for maximum energy efficiency.
• Modern design with polished glass-like surface and touch-screen operation.
• Intended for mounting directly on the wall or on an electrical installation box.
• The thermostat settings can be locked by performing a button combination.
• Simple function check via LED
