Grenton ACC-014-R-12 Thermoelectric Actuator (NC, 24V, M30x1.5)

The Grenton ACC-014-R-12 thermoelectric actuator is a normally closed (NC) device designed for zone and thermostatic valves in underfloor heating manifolds. The model features a 24 V AC/DC power supply, an M30 x 1.5 connection thread, and a First Open function to facilitate system startup.

The Grenton ACC-014-R-12 normally closed (NC) thermoelectric actuator is used to control fluid flow in heating systems. The device is dedicated for use with zone or thermostatic valves in underfloor heating manifolds. It requires a rated voltage of 24 V AC/DC to operate, and its power consumption in the open state is 2 W. The product is equipped with a practical First Open function, which allows fluid to flow without electrical power supply during the system installation and startup phase.

Key features

• Dedicated for zone valves and underfloor heating manifolds
• First Open function facilitating heating system startup without power supply
• Default voltage-free state: normally closed (NC)
• Vertical, top-down installation
