Danfoss RA 2916 — self-acting thermostatic radiator sensor (control head) for Danfoss RA, RA-N and RA 2000 radiator valve bodies, OEM order code 013G2916. The RA 2916 is a gas-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 gas charge gives a fast sensor response. An air-sensing element on a 2 m capillary lets the sensor be sited away from the valve, for radiators that are concealed or in a cabinet where the air at the valve is not representative of the room. Setpoint range 5 °C - 20 °C, with a frost-protection setting and provision for maximum/minimum limiting and locking of the set-point. Mounts to the valve for Danfoss RA / RA-N bodies. Genuine Danfoss part; specification quoted from store.danfoss.com (code 013G2916). OEM P/N 013G2916, EAN 5702420054841. HS 9032.10.
