## Summary description

Thermostatic head ARCO 880040 is a radiator valve actuator designed for automatic room temperature control. It mounts on compatible thermostatic radiator valves to adjust flow through the radiator based on its setpoint. Suitable for residential and commercial heating systems, it provides simple manual setpoint adjustment and integrates with standard valve bodies for zonal temperature regulation.

## Long description

Thermostatic head ARCO 880040 is a radiator valve actuator designed to provide automatic room temperature control by adjusting the flow through compatible thermostatic radiator valves. The unit mounts directly on standard valve bodies and enables manual setpoint selection to maintain the required ambient temperature. Intended for use in residential and light commercial heating systems, the actuator supports zonal regulation and straightforward integration with existing radiator valves.
Advantages
The ARCO 880040 provides precise proportional control of radiator flow based on the selected setpoint, helping to maintain stable room temperatures. Its mechanical adjustment knob offers simple and intuitive manual operation without the need for additional controllers. The actuator is compact and compatible with common thermostatic valve fittings, which facilitates replacement or upgrade of existing radiator valves. Reliable operation and low maintenance needs make it suitable for continuous use in everyday heating applications.
Suitable for
 Single-room temperature control in apartments and homes
 Zonal heating control in commercial offices and small public buildings
 Replacement of manual or worn thermostatic heads on compatible radiator valves
 Integration into hydronic heating systems requiring per-radiator regulation
Key specifications
 Function: Manual thermostatic radiator valve actuator for automatic temperature regulation
 Mounting: Fits standard thermostatic valve bodies (mechanical mounting interface)
 Control: Mechanical setpoint adjustment for proportional flow control
 Use environment: Designed for residential and light commercial heating systems
 Construction: Compact design suitable for limited space installations
How to use
Mount the thermostatic head onto a compatible radiator valve following the valve manufacturer’s mounting instructions, ensuring a secure mechanical connection. Set the desired room temperature by turning the adjustment knob to the required position; the actuator will modulate the valve to regulate hot water flow accordingly. Periodically check the actuator mounting and the valve for proper operation, and adjust the setpoint as needed to account for seasonal temperature changes.
Usage recommendations
Install the ARCO thermostatic head on valves that match the actuator’s mechanical interface and within the recommended ambient temperature range for the heating system. Avoid covering the head with curtains or furniture to ensure accurate room temperature sensing. For best zonal control, use one actuator per radiator and balance the system hydraulically if multiple radiators are fitted with thermostatic heads.
