Thermal actuator for heating, ventilation, and air conditioning systems

The EMOtec thermal actuator, First-Open with position indicator (NC), can be installed in temperature and/or time related 2-point control systems. The first-open function keeps the actuator open until the individual room control is commissioned.

Key features

Normally closed version with First-Open function

Compact sizes especially suited to manifold cabinets

Simple functional testing by means of position indicator

Trouble-free because it is silent and needs no maintenance
