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
