⚡ At a Glance
- • Operating Power: Extremely efficient, operating power only 1 Watt
- • Best for: Homeowners and installers replacing actuator heads on compatible distributors
- • Not ideal for: Systems that require an integrated or non-standard external power supply
Electric actuator for automatic control of return valves on heating distributors, rated for 230 V use. Supplied with a 1,000 mm connection cable and compatible with common distributor fittings named in the description.
Hassle-free replacement – With compatibility for Heimeier/Kermi/Roth/Herb/Thermoval
Compatibility is stated for a range of common distributor makes, allowing the actuator to mate with existing adapter rings and fittings. A standard mechanical interface and mounting pattern match typical distributor valve heads.
Installers can swap actuator heads without changing valve hardware, cutting installation time and avoiding extra parts.
Low running costs – Thanks to extremely efficient 1 Watt operating power
Operating consumption is listed at approximately 1 Watt during normal operation, which minimises electrical load compared with higher-power actuators. The low draw keeps ongoing energy use to a minimum over many cycles.
Reduced electricity use lowers ongoing operating costs and suits systems where minimal power draw is preferred.
Straightforward wiring – With 1,000 mm connection cable included
A 1,000 mm connection cable is supplied ready-fitted for direct connection to the distributor wiring. The cable length provides flexibility to reach nearby thermostats or junction points without added extensions.
On-site wiring is quicker and cleaner, reducing the need to source extra cables during installation.
