Busch-Jaeger Room Temperature Controller Object Range 6109/08 (2CKA006134A0312)

The Busch-Jaeger Room Temperature Controller 6109/08 brings precise mechanical bimetal control to flush-mounted heating applications. Unlike digital thermostats that rely on electronics and power, this unit uses a robust bimetal sensor for dependable switching without standby consumption. It is built for the Busch-Jaeger switch range and includes an ON/OFF switch plus a control lamp for heating operation, giving you clear status at a glance.

Highlights

• Mechanical bimetal control for heating systems
• Flush-mounted design for standard switch ranges
• Thermal feedback and ON/OFF switch
• Control lamp indicates heating operation
• Alpine white central plate

In daily use

Set the desired temperature between +5 °C and +30 °C with the rotary knob. The internal bimetal sensor reacts to room temperature changes with a switching differential of approximately 0.5 K, ensuring comfortable regulation. The integrated ON/OFF switch allows you to switch off the heating function when not needed, while the control lamp provides visual confirmation of active heating.
