Danfoss RAX-K 6080 — self-acting thermostatic radiator sensor (control head) for radiator valve bodies with an M30 x 1.5 mm thermostat connection, OEM order code 013G6080. The RAX-K 6080 is a liquid-charged operator that modulates the radiator valve in proportion to room air temperature, holding a set room temperature without any external power or wiring; the liquid charge gives stable, hysteresis-controlled operation. The temperature-sensing element is built into the setpoint dial, sensing the air immediately around the valve. Setpoint range 8 °C - 28 °C, with a frost-protection setting and provision for maximum/minimum limiting and locking of the set-point. Mounts to the valve for M30 x 1.5 mm valves bodies.
