The MENRED TM20.23 is a compact electro-thermal actuator designed to control water flow through floor heating manifolds, small valves and compatible HVAC valves.
A low-power wax element driven by PTC heating converts the electrical control signal into mechanical movement. The actuator operates quietly and uses a spring-return mechanism for reliable valve control in hydronic heating and cooling systems.

In a typical zoned floor heating system, the actuator receives an electrical signal from the thermostat or wiring center and operates the corresponding manifold valve to control water flow through the heating circuit.
TM20.23 uses an M30 × 1.5 mm valve connection. Always verify the valve or manifold interface and required actuator stroke before selection.
For multi-zone hydronic floor heating, TM20.23 actuators can be integrated with room thermostats and a central wiring center to provide individual zone control.
