Small linear thermal actuator designed for two-position control (open/close) in room heating and cooling systems, such as radiators, fan coil units, underfloor heating, cooling ceilings, and convectors.

• Standard mounting thread M30 x 1.5 for attachment to heating/cooling valves, radiator thermostatic valves, and valve inserts of compact radiators or distributors.
• Adapted for standard closing ranges (11.5 mm ± 0.3 mm).
• Special adapters for different types of valves available.
• Cable length - 1 m, longer cables available.

Recommended controllers: Excel 10 and Excel 12 (use with non-Honeywell controllers may adversely affect PWM operation).

FEATURES

• Installation without the need for special tools (easy fitting onto the valve using an adapter).
• Water-resistant casing allows for any mounting position.
• Cable with plug for easy installation and maintenance.
• Types with end switch for pumps and fans.
• Modes: power off open / power off closed
• Compact design allows installation in confined spaces.
• Indicator for valve position and actuator mode (NC/NO).
• Silent operation.
• Long-term reliable operation.
• Overvoltage protection (4 kV) for 230 VAC types.
