3 Function
The unit switches the two complementary outputs OUT1 / OUT2:
With rising temperature OUT1 closes / OUT2 opens when the value SET is
reached.
With falling temperature OUT1 opens / OUT2 closes when the value RESET is
reached.

4 Installation
Before mounting and removing the unit:
► Ensure that no medium can leak at the process connection.
Horizontal mounting recommended for high medium temperatures.
► Insert the unit in a process connection and tighten firmly. Recommended
Tightening torque:
- Process connection G ¼: 35 Nm
Hnc = normally closed
- Process connection ¼" NPT: 1.5 turns past hand tight

► Turn the locking ring to the unlocked position.
► Turn both setting rings to the lowest setting.
This is important to ensure the setting accuracy.
► Rotate SET ring to desired temperature.
► Rotate RESET ring to desired temperature.
The RESET value must be lower than the SET value.
Minimum distance between SET and RESET = 3 K (= hysteresis).
► Turn the locking ring to the locked position.
