Danfoss Thermot electrothermal (thermal-wax) valve actuator, OEM order code 088H3230. The Thermot converts a switching signal from a room thermostat or controller into valve movement on hydronic floor-heating manifolds and radiator/zone valves — no auxiliary air or hydraulics. Normally closed (NC) — the valve is closed when de-energised and opens when the actuator is powered. Supply voltage 230 V AC (50/60 Hz), power consumption 2 W. M 30 x 1.5 connection. 0.6 m connecting cable. Enclosure rating IP41. Net weight 0.112 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3230). OEM P/N 088H3230.

Electrothermal actuator for Danfoss M 30 x 1.5 valve/manifold connections. Signalled by a 230 V AC room-thermostat/controller output — match the supply voltage (230 V AC) and valve function (normally closed (NC)) to the control system. Confirm the valve connection (M 30 x 1.5) against the manifold or valve body before ordering.
