Description
Simple switch point setting by means of two setting rings allowing optimum reading
Setting of the switch points without system temperature being applied
Two switching outputs with fixed hysteresis
Particularly good response dynamics and very short power-on delay time
Mechanical locking prevents inadvertent switch point manipulation
