H-Tronic TLF 1000 lämpötilakytkin -25...+70 °C 1114660

The H-Tronic TLF 1000 stands out with its wide -25 to +70 °C control range and selectable heating or cooling mode, making it suitable for both frost protection and overtemperature shutdown. The external NTC sensor on a 2 m cable allows flexible placement away from the control unit.

Highlights

• Adjustable switching hysteresis from 0.5 to 10 °C
• 3-digit LED display with 0.1 °C resolution
• SPDT relay output rated up to 10 A / 2300 W
• Sensor protection class IP67 for demanding environments

In daily use

The TLF 1000 is wall-mounted and connected via screw terminals. Two LEDs indicate the selected operating mode and relay status. With a power consumption of approximately 2 W, it remains efficient in continuous operation.
