The MENRED AN7.N series combines a forged H59 brass manifold with SEH20.23 mini thermal actuators for hydronic underfloor heating. Available in 2–8 circuit configurations, it provides supply-side static adjustment and return-side valve control for residential heating systems.
Supply valves allow circuit flow to be adjusted during hydraulic balancing. Return valves are operated by the included thermal actuators, allowing compatible room thermostats and wiring controls to open or close the corresponding heating circuits.

PN10 is the nominal pressure classification. The stated temperature range is a component specification; actual underfloor-heating water temperature and operating pressure must follow the system design.

A and B refer to the corresponding dimensions in the product drawing. Dimension B is not specified for AN7.N2. Confirm installation space with the complete assembly drawing, including connectors, end fittings and actuator clearance.
SEH20.23 mini thermal actuators are included in the documented AN7.N configuration. They connect to the return valves through an M30 × 1.5 interface and support manual valve operation as described in the installation instructions.
For room control, compatible thermostats send heating demand through suitable wiring controls to the actuators. One room may use more than one heating loop, so circuit count and thermostat zone count should be selected separately.
Confirm the supplied actuator voltage, normally closed or normally open operation, thermostat output and wiring-center compatibility before ordering.

Send MENRED your heating-loop count, pipe dimensions, control voltage and installation-space requirements for model and accessory selection.
Contact MENREDYes. The documented AN7.N package includes SEH20.23 mini thermal actuators. Confirm the actuator electrical configuration when ordering.
The AN7.N series is available with 2–8 heating circuits, from AN7.N2 to AN7.N8. Circuit count does not necessarily equal room-control zone count.
The supply valves provide static circuit flow adjustment for hydraulic balancing. The return valves are opened or closed by thermal actuators through compatible room controls.
No. Pipe connectors and end fittings are ordered separately. Connectors must match the pipe dimensions and manifold branch interface.
Confirm actuator voltage, normally closed or normally open operation, thermostat output, wiring-center compatibility and the required arrangement of heating circuits and control zones.
