TR-04040 Duct temperature controller two-step 0...+40 °C

Duct temperature controller two-step 0...+40 °C

Temperature range 0...+40 °C and 0..+40 °C, hysteresis 1 K and 1 K, change-over contacts 10 (1.5) A, 24...250 V AC, IP65, dimensions 72.5 x 70 x 108 mm


The TR... is a series of mechanical thermostats for water, hot water, gases, and room air.  

  • HVAC systems – heat exchange stations, DHW preparation, safety elements at heating circuits, room temperature controls, industrial cooling, etc.

The measuring element actuates changeover contacts. Contacts 2 – 3 open if the temperature is higher than the setpoint.

The devices do not need any servicing or maintenance and can be mounted in any position except those when condensate may cumulate at operating elements or cable glands. 

The temperature sensing elements, torsion element with liquid filling, are mounted into pockets which are part of delivery.
